139-610: Common products and services for which no-frills brands exist include budget airlines , supermarkets , vacations and used vehicles . No-frills supermarkets are recognisable by their store design and business model. Examples of no-frills supermarket chains include: *Dia and Ed are all part of the Dia Group, which is in turn part of the Carrefour Group. ( Brazil , Spain ) American supermarket chain Pathmark used "No Frills" as

278-400: A budget , or discount carrier or airline , is an airline that is operated with an emphasis on minimizing operating costs. It sacrifices certain traditional airline luxuries for cheaper fares. To make up for revenue lost in decreased ticket prices, the airline may charge extra fees, such as for carry-on baggage. The term originated within the airline industry referring to airlines with

417-420: A cigarette lighter and dome light were not present. Buyers were allowed to buy only a low-cost heater and a few other trim and convenience items from a short options list; a radio was not offered as an option on this model (unlike Studebaker's more expensive models). During the 1960s and early 1970s, American automakers offered several trim levels of full-sized models (each having a different name), with

556-426: A cost of available seat mile (CASM) advantage in relation to the traditional and established, legacy airlines such as Trans World Airlines and American Airlines . Often this CASM advantage has been attributed solely to the lower labor costs of the newly hired and lower pay grade workers of new start-up carriers, such as ValuJet , Midway Airlines, and their like. However, these lower costs can also be attributed to

695-506: A house brand . In the United States, a no-frills automobile model typically has a minimum of convenience equipment, a less powerful engine and spartan trim. Frequently, these models represent the lowest-priced version of a larger selection of more lavishly equipped and trimmed models of that same car. Often, the less-expensive models are sold with a manual transmission and have a shorter options list. Early 1950s American examples include

834-491: A precipitate of aluminium hydroxide , Al(OH) 3 , forms. This is useful for clarification of water, as the precipitate nucleates on suspended particles in the water, hence removing them. Increasing the pH even further leads to the hydroxide dissolving again as aluminate , [Al(H 2 O) 2 (OH) 4 ] , is formed. Aluminium hydroxide forms both salts and aluminates and dissolves in acid and alkali, as well as on fusion with acidic and basic oxides. This behavior of Al(OH) 3

973-515: A "less classical sound". This name persisted: although the -um spelling was occasionally used in Britain, the American scientific language used -ium from the start. Most scientists throughout the world used -ium in the 19th century; and it was entrenched in several other European languages, such as French , German , and Dutch . In 1828, an American lexicographer, Noah Webster , entered only

1112-492: A Swedish chemist, Jöns Jacob Berzelius , in which the name aluminium is given to the element that would be synthesized from alum. (Another article in the same journal issue also refers to the metal whose oxide is the basis of sapphire , i.e. the same metal, as to aluminium .) A January 1811 summary of one of Davy's lectures at the Royal Society mentioned the name aluminium as a possibility. The next year, Davy published

1251-490: A chemistry textbook in which he used the spelling aluminum . Both spellings have coexisted since. Their usage is currently regional: aluminum dominates in the United States and Canada; aluminium is prevalent in the rest of the English-speaking world. In 1812, British scientist Thomas Young wrote an anonymous review of Davy's book, in which he proposed the name aluminium instead of aluminum , which he thought had

1390-854: A domestic legacy airline and one or more foreign investors. By mid-2013, these new LCCs were operating at a unit cost of around 8 yen per seat-kilometer, compared to 10–11 yen per seat-kilometer for domestic legacy airlines. However, their unit cost was still much higher than the 3 yen per seat-kilometer for AirAsia in Malaysia , due to the higher cost of landing fees and personnel in Japan. By 2017, low-cost carriers had achieved market share of 57.2% in South Asia and 52.6% in Southeast Asia. Market share remained somewhat lower in Europe at 37.9% and North America at 32.7%. For

1529-422: A flight on a full-service carrier. Most airlines charge additional taxes and fees on their tickets. Some low-cost airlines have been known to charge fees for the seemingly ridiculous, such as levying a credit card charge if credit card is the only payment method accepted. While tour and package operators have offered lower-priced, lower-frilled traveling for a large part of modern airline history, not until during

1668-541: A greater number of add-on fees. In the US market, Allegiant Air , Frontier Airlines , Spirit Airlines , and Sun Country Airlines are considered to be ULCCs. In Europe, Ryanair and Wizz Air are the most prominent ULCCs. In Asia, AirAsia and Lion Air are the most prominent ULCCs. The pricing policy of the low-cost carriers is usually very dynamic as befits their business model, with frequent discounts and tickets in promotion. Like other carriers, however, even if

1807-552: A higher age limit on unaccompanied minors than full-service carriers. Often these airlines do not offer connecting tickets, since the airline will have to pay for ground crew to transfer luggage. A customer may create a connection manually by purchasing two separate tickets, but these are considered separate contracts, and the passenger bears the risk if a delayed inbound flight causes a missed connection. When most countries had national monopolies, crews could negotiate pay raises and good pension benefits (something that costs money for

1946-778: A large-scale reduction of its fleet of Boeing 737 aircraft and operations. In March 2017, International Airlines Group established Level , a long-haul low-cost virtual airline based in Barcelona Airport and serving destinations in North and South America. Long-haul low-cost carriers are emerging on the transatlantic flights market with 545,000 seats offered over 60 city pairs in September 2017 (a 66% growth over one year), compared to 652,000 seats over 96 pairs for Leisure airlines and 8,798,000 seats over 357 pairs for mainline carriers . Former American Airlines CEO Bob Crandall thinks

2085-1109: A lower operating cost structure than their competitors. The term is often applied to any carrier with low ticket prices and limited services regardless of their operating models. Low-cost carriers should not be confused with regional airlines that operate short-haul flights without service, or with full-service airlines offering some reduced fares. Some airlines advertise themselves as low-cost while maintaining products usually associated with traditional mainline carriers’ services. These products include preferred or assigned seating , catering, differentiated premium cabins , satellite or ground-based Wi-Fi internet, and in-flight audio and video entertainment . The term ultra low-cost carrier ( ULCC ) has been used, particularly in North America and Europe to refer to carriers that do not provide these services and amenities. The low-cost carrier business model practices vary widely. Some practices are more common in certain regions, while others are generally universal. The common theme among all low-cost carriers

2224-506: A manual transmission. Most no-frills cars are sold to fleet buyers, such as taxi companies or police departments. However, these models are generally available to cost-conscious private customers whose primary concerns were price, fuel economy and basic low-cost transportation. The concept of a no-frills car in the European market was common in the 1950s with cars such as the Ford Abeille or

2363-519: A minimum set of equipment, further reducing costs of acquisition and maintenance, as well as keeping the weight of the aircraft lower and thus saving fuel. Depending on the low-cost airline seats do not recline and do not have rear pockets, to reduce cleaning and maintenance costs. Others have no window shades. Pilot conveniences, such as ACARS , may be excluded. Often, no in-flight entertainment systems are made available, though many US low-cost carriers do offer satellite television or radio in-flight. It

2502-411: A no-frills airline may charge passengers an additional fee for check-in luggage, using airport check-in desks, or even providing wheelchairs . Based on the no-frills airline model, the recent liberalisation of rail licensing in Europe has brought about a no-frills budget rail travel industry. Examples include; Another example of a type of no frills service is lodgings. In more extreme circumstances,

2641-460: A page from the mainline, major, or legacy carriers' desire to reduce costs in all ways possible in regards regional route networks by outsourcing regional operations to the lowest expense airline bidder capable of operating regional aircraft, a new generation of low-cost airlines (in name only) soon evolved in the US with varying levels of success. Among these varieties of low-cost and discount operators were noteworthy starts-ups that managed to get off

2780-541: A price-leading no-frills versions. Examples included the Chevrolet Biscayne , Ford Custom 500 , and Plymouth Fury I . While ostensibly targeted toward fleet buyers and business customers where luxury is not a concern, these cars were also available to private customers. While many of these cars were typically sold with the standard six-cylinder or basic V-8 engine with the standard three-speed manual transmission, many of these price-leading models were also available with

2919-441: A probable cause for it being soft with a low melting point and low electrical resistivity . Aluminium metal has an appearance ranging from silvery white to dull gray depending on its surface roughness . Aluminium mirrors are the most reflective of all metal mirrors for near ultraviolet and far infrared light. It is also one of the most reflective for light in the visible spectrum, nearly on par with silver in this respect, and

SECTION 20

3058-683: A process termed passivation . Because of its general resistance to corrosion, aluminium is one of the few metals that retains silvery reflectance in finely powdered form, making it an important component of silver-colored paints. Aluminium is not attacked by oxidizing acids because of its passivation. This allows aluminium to be used to store reagents such as nitric acid , concentrated sulfuric acid , and some organic acids. In hot concentrated hydrochloric acid , aluminium reacts with water with evolution of hydrogen, and in aqueous sodium hydroxide or potassium hydroxide at room temperature to form aluminates —protective passivation under these conditions

3197-525: A refractory material, and in ceramics , as well as being the starting material for the electrolytic production of aluminium. Sapphire and ruby are impure corundum contaminated with trace amounts of other metals. The two main oxide-hydroxides, AlO(OH), are boehmite and diaspore . There are three main trihydroxides: bayerite , gibbsite , and nordstrandite , which differ in their crystalline structure ( polymorphs ). Many other intermediate and related structures are also known. Most are produced from ores by

3336-523: A simple fare scheme, in which fares typically increase during peak seasons, and also as more people sign up for the holiday. This rewards early reservations, and is known as " yield management ". Examples of no-frills holiday companies are: Compared to regular fitness gyms, there has been a growing number of no frills gyms. No frills gyms are significantly different from regular gyms in the amenities offered. The ways in which these differ are: Examples of no frills gyms are easyGym, Fit4less and PureGym in

3475-463: A simpler fare scheme, such as selling only one-way tickets. Typically fares increase as the plane fills up, which rewards early reservations. In Europe (and early in Southwest's history) luggage is not transferred from one flight to another, even if both flights are with the same airline. This saves costs and is thought to encourage passengers to take direct flights. Tickets are not sold with transfers, so

3614-449: A single aircraft type, so that cabin and ground crew will only have to be trained to work on one type of aircraft. This is also beneficial from a maintenance standpoint as spare parts and mechanics will only be dedicated to one type of aircraft. These airlines tend to operate short-haul flights that suit the range of narrow-body (single aisle) planes. As of lately, however, there is also a rise in demand for long range low-cost flights and

3753-430: A single type of aircraft. Aircraft cabin interiors may be fitted out with minimum comforts, dispensing with luxuries such as seat-back video screens, reclining seats and blinds; some airlines choose to carry advertising inside the cabin to increase revenue. Should meals be served, they must be paid for in full. Some airlines also extend the definition of "frills" to include standard services and conveniences; for example,

3892-474: A stable noble gas configuration. Accordingly, the combined first three ionization energies of aluminium are far lower than the fourth ionization energy alone. Such an electron configuration is shared with the other well-characterized members of its group, boron , gallium , indium , and thallium ; it is also expected for nihonium . Aluminium can surrender its three outermost electrons in many chemical reactions (see below ). The electronegativity of aluminium

4031-815: A variety of wet processes using acid and base. Heating the hydroxides leads to formation of corundum. These materials are of central importance to the production of aluminium and are themselves extremely useful. Some mixed oxide phases are also very useful, such as spinel (MgAl 2 O 4 ), Na-β-alumina (NaAl 11 O 17 ), and tricalcium aluminate (Ca 3 Al 2 O 6 , an important mineral phase in Portland cement ). The only stable chalcogenides under normal conditions are aluminium sulfide (Al 2 S 3 ), selenide (Al 2 Se 3 ), and telluride (Al 2 Te 3 ). All three are prepared by direct reaction of their elements at about 1,000 °C (1,800 °F) and quickly hydrolyze completely in water to yield aluminium hydroxide and

4170-567: A way of purifying bauxite to yield alumina, now known as the Bayer process , in 1889. Modern production of aluminium is based on the Bayer and Hall–Héroult processes. As large-scale production caused aluminium prices to drop, the metal became widely used in jewelry, eyeglass frames, optical instruments, tableware, and foil , and other everyday items in the 1890s and early 20th century. Aluminium's ability to form hard yet light alloys with other metals provided

4309-752: A week, and Melbourne thrice weekly. On 11 March 2009, AirAsia X started its first low-cost long-haul service into Europe, to London Stansted . The daily flights are operated by two leased Airbus A340 -300s. A one-way economy-class ticket often costs £150, and the premium-class one-way often costs £350. On 12 January 2012, AirAsia announced that it would be suspending services to London on 1 April 2012. Low-cost European airline, Norwegian Air Shuttle , started long-haul low-cost operations in May 2013 under their Norwegian Long Haul arm. Norwegian initially operated flights to Bangkok and New York from Scandinavia using leased Airbus A340 aircraft, switching to new Boeing 787s in

4448-434: Is Al. Al was present in the early Solar System with abundance of 0.005% relative to Al but its half-life of 728,000 years is too short for any original nuclei to survive; Al is therefore extinct . Unlike for Al, hydrogen burning is the primary source of Al, with the nuclide emerging after a nucleus of Mg catches a free proton. However, the trace quantities of Al that do exist are the most common gamma ray emitter in

4587-407: Is paramagnetic and thus essentially unaffected by static magnetic fields. The high electrical conductivity, however, means that it is strongly affected by alternating magnetic fields through the induction of eddy currents . Aluminium combines characteristics of pre- and post-transition metals. Since it has few available electrons for metallic bonding, like its heavier group 13 congeners, it has

4726-429: Is small and highly charged ; as such, it has more polarizing power , and bonds formed by aluminium have a more covalent character. The strong affinity of aluminium for oxygen leads to the common occurrence of its oxides in nature. Aluminium is found on Earth primarily in rocks in the crust , where it is the third-most abundant element , after oxygen and silicon , rather than in the mantle , and virtually never as

4865-483: Is 1.61 (Pauling scale). A free aluminium atom has a radius of 143  pm . With the three outermost electrons removed, the radius shrinks to 39 pm for a 4-coordinated atom or 53.5 pm for a 6-coordinated atom. At standard temperature and pressure , aluminium atoms (when not affected by atoms of other elements) form a face-centered cubic crystal system bound by metallic bonding provided by atoms' outermost electrons; hence aluminium (at these conditions)

5004-399: Is a chemical element ; it has symbol   Al and atomic number  13. Aluminium has a density lower than that of other common metals , about one-third that of steel . It has a great affinity towards oxygen , forming a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver , both in its color and in its great ability to reflect light. It

5143-548: Is a metal. This crystal system is shared by many other metals, such as lead and copper ; the size of a unit cell of aluminium is comparable to that of those other metals. The system, however, is not shared by the other members of its group: boron has ionization energies too high to allow metallization, thallium has a hexagonal close-packed structure, and gallium and indium have unusual structures that are not close-packed like those of aluminium and thallium. The few electrons that are available for metallic bonding in aluminium are

5282-515: Is almost never found in the elemental state; instead it is found in oxides or silicates. Feldspars , the most common group of minerals in the Earth's crust, are aluminosilicates. Aluminium also occurs in the minerals beryl , cryolite , garnet , spinel , and turquoise . Impurities in Al 2 O 3 , such as chromium and iron , yield the gemstones ruby and sapphire , respectively. Native aluminium metal

5421-575: Is also becoming a popular approach to install LCD monitors onto the aircraft and broadcast advertisements on them, coupled with the traditional route–altitude–speed information. Some allow priority boarding for an extra fee instead of reserved seating, and some allow reserving a seat in an emergency exit row (for longer leg room) at an extra cost. Like the major carriers, many low-cost carriers develop one or more bases to maximize destination coverage and defend their market. Many do not operate traditional hubs , but rather focus cities . Airlines often offer

5560-405: Is also easily machined and cast . Aluminium is an excellent thermal and electrical conductor , having around 60% the conductivity of copper , both thermal and electrical, while having only 30% of copper's density. Aluminium is capable of superconductivity , with a superconducting critical temperature of 1.2 kelvin and a critical magnetic field of about 100 gauss (10 milliteslas ). It

5699-546: Is extremely rare and can only be found as a minor phase in low oxygen fugacity environments, such as the interiors of certain volcanoes. Native aluminium has been reported in cold seeps in the northeastern continental slope of the South China Sea . It is possible that these deposits resulted from bacterial reduction of tetrahydroxoaluminate Al(OH) 4 . Although aluminium is a common and widespread element, not all aluminium minerals are economically viable sources of

5838-536: Is greatly reduced by aqueous salts, particularly in the presence of dissimilar metals. Aluminium reacts with most nonmetals upon heating, forming compounds such as aluminium nitride (AlN), aluminium sulfide (Al 2 S 3 ), and the aluminium halides (AlX 3 ). It also forms a wide range of intermetallic compounds involving metals from every group on the periodic table. The vast majority of compounds, including all aluminium-containing minerals and all commercially significant aluminium compounds, feature aluminium in

5977-492: Is in fact more basic than that of gallium. Aluminium also bears minor similarities to the metalloid boron in the same group: AlX 3 compounds are valence isoelectronic to BX 3 compounds (they have the same valence electronic structure), and both behave as Lewis acids and readily form adducts . Additionally, one of the main motifs of boron chemistry is regular icosahedral structures, and aluminium forms an important part of many icosahedral quasicrystal alloys, including

6116-470: Is low in comparison with many other metals. All other isotopes of aluminium are radioactive . The most stable of these is Al : while it was present along with stable Al in the interstellar medium from which the Solar System formed, having been produced by stellar nucleosynthesis as well, its half-life is only 717,000 years and therefore a detectable amount has not survived since the formation of

6255-500: Is negligible. Aqua regia also dissolves aluminium. Aluminium is corroded by dissolved chlorides , such as common sodium chloride , which is why household plumbing is never made from aluminium. The oxide layer on aluminium is also destroyed by contact with mercury due to amalgamation or with salts of some electropositive metals. As such, the strongest aluminium alloys are less corrosion-resistant due to galvanic reactions with alloyed copper , and aluminium's corrosion resistance

6394-515: Is not as important. It is a polymer with the formula (AlH 3 ) n , in contrast to the corresponding boron hydride that is a dimer with the formula (BH 3 ) 2 . Aluminium's per-particle abundance in the Solar System is 3.15 ppm (parts per million). It is the twelfth most abundant of all elements and third most abundant among the elements that have odd atomic numbers, after hydrogen and nitrogen. The only stable isotope of aluminium, Al,

6533-416: Is quite soft and lacking in strength. In most applications various aluminium alloys are used instead because of their higher strength and hardness. The yield strength of pure aluminium is 7–11 MPa , while aluminium alloys have yield strengths ranging from 200 MPa to 600 MPa. Aluminium is ductile , with a percent elongation of 50-70%, and malleable allowing it to be easily drawn and extruded . It

6672-435: Is soft, nonmagnetic , and ductile . It has one stable isotope, Al, which is highly abundant, making aluminium the twelfth-most common element in the universe. The radioactivity of Al leads to it being used in radiometric dating . Chemically, aluminium is a post-transition metal in the boron group ; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state . The aluminium cation Al

6811-422: Is surrounded by six fluorine atoms in a distorted octahedral arrangement, with each fluorine atom being shared between the corners of two octahedra. Such {AlF 6 } units also exist in complex fluorides such as cryolite , Na 3 AlF 6 . AlF 3 melts at 1,290 °C (2,354 °F) and is made by reaction of aluminium oxide with hydrogen fluoride gas at 700 °C (1,300 °F). With heavier halides,

6950-547: Is termed amphoterism and is characteristic of weakly basic cations that form insoluble hydroxides and whose hydrated species can also donate their protons. One effect of this is that aluminium salts with weak acids are hydrolyzed in water to the aquated hydroxide and the corresponding nonmetal hydride: for example, aluminium sulfide yields hydrogen sulfide . However, some salts like aluminium carbonate exist in aqueous solution but are unstable as such; and only incomplete hydrolysis takes place for salts with strong acids, such as

7089-416: Is that of the preceding noble gas , whereas those of its heavier congeners gallium , indium , thallium , and nihonium also include a filled d-subshell and in some cases a filled f-subshell. Hence, the inner electrons of aluminium shield the valence electrons almost completely, unlike those of aluminium's heavier congeners. As such, aluminium is the most electropositive metal in its group, and its hydroxide

7228-433: Is the eighteenth most abundant nucleus in the universe. It is created almost entirely after fusion of carbon in massive stars that will later become Type II supernovas : this fusion creates Mg, which upon capturing free protons and neutrons, becomes aluminium. Some smaller quantities of Al are created in hydrogen burning shells of evolved stars, where Mg can capture free protons. Essentially all aluminium now in existence

7367-400: Is the reduction of cost and reduced overall fares compared to legacy carriers. Traditional airlines have also reduced their cost using several of these practices. Most low-cost carriers operate aircraft configured with a single passenger class, and some low-cost carriers choose to operate more than one type and configure their aircraft with more than one passenger class, but most operate just

7506-420: Is well known for using fuel hedging programs to reduce its overall fuel costs. Check-in at the gate of luggage requires fees, as it requires addition to the weight calculation and last-minute baggage handling. Online check-in is becoming common, again in the interest of avoiding personnel costs. Where permissible, some airlines have a disinclination to handle Special Service passengers, for instance by placing

7645-456: Is why Ryanair flies to Gatwick Airport , Luton Airport , and Stansted Airport in the London area and how easyJet is able to fly to Paris-Charles de Gaulle , and Amsterdam Airport Schiphol . In London's case however, low-cost carriers would not be able to use Heathrow as the airport is running at near capacity, so there is no room to build a base. The airlines tend to offload, service and re-load

7784-871: The Austrian chain Diskont . A few Nintendo gaming systems have model revisions that strip out non-essential features, such as the Wii 's Wii Mini , the Game Boy Advance 's Game Boy Micro and the Nintendo Switch 's Switch Lite . Other examples of no-frills companies include: cinemas ( easyCinema ), bus companies ( easyBus , Magic Bus (Stagecoach) , Eastern ), food ranges ( Tesco Value, Walmart / Asda SmartPrice), mobile phone companies (easyMobile, Telmore), and marketing (low-cost marketing). Budget airline A low-cost carrier ( LCC ) or low-cost airline , also called

One of the more famous no-frills cars was the Studebaker Scotsman , which was on sale from 1957 to 1959. These cars came with a low-grade cloth-trimmed front seat and contained only a driver's side sun visor, minimal soundproofing, no door armrests and painted trim (in lieu of chrome trim); even routine convenience items, such as

8062-496: The Citroën ID Normale . The Dacia Logan is an example of a recent no-frills car in Europe. Another example is Fiat Albea . In Argentina and Brazil, the no-frills category takes a considerable share of the new car market. Examples of cost cuts in base versions include: In some markets, often in the developing world, very aggressive forms of no-frills cars may be available. For example, the supermini and city cars sold in

8201-826: The European Commission , the LCCs market share (44.8%) exceeded legacy carriers (42.4%) in 2012: between 2002 and 2017, LCC share of international seat capacity rose from 23% to 57% in the UK, from 10% to 55% in Italy and from 9% to 56% in Spain but have still room for growth in domestic seat-capacity In France with 19% and in Germany with 25% in 2017, compared with 66% in the UK, 48% in Spain and 47% in Italy. By early 2019, there were more than 100 LCCs operating 6,000 aircraft, doubled from 2,900 aircraft at

8340-455: The Friedel–Crafts reactions . Aluminium trichloride has major industrial uses involving this reaction, such as in the manufacture of anthraquinones and styrene ; it is also often used as the precursor for many other aluminium compounds and as a reagent for converting nonmetal fluorides into the corresponding chlorides (a transhalogenation reaction ). Aluminium forms one stable oxide with

8479-466: The London Metal Exchange , the oldest industrial metal exchange in the world, in 1978. The output continued to grow: the annual production of aluminium exceeded 50,000,000 metric tons in 2013. The real price for aluminium declined from $ 14,000 per metric ton in 1900 to $ 2,340 in 1948 (in 1998 United States dollars). Extraction and processing costs were lowered over technological progress and

A no-frills airline will typically cut overhead by flying from more remote airports (with lower access charges) and by using

8757-825: The UK and Canada for £89. In August 2006, Zoom announced a UK subsidiary to offer low-cost long-haul flights to the United States and India, but suspended its operations from 28 August 2008 due to high fuel prices inducing financial problems. In 2005, Emirates ' Tim Clark viewed long-haul low-cost as inevitable, flights could be operated on 760 seats all-economy Airbus A380s , or 870 for an hypothetical A380 stretch. Since 2005, Australia's Jetstar Airways operates international flights, starting with Christchurch , New Zealand. In late 2006, others followed from Sydney , Melbourne and Brisbane , to popular tourist destinations within 10 hours like Honolulu , Japan, Vietnam , Thailand and Malaysia . With new aircraft deliveries, it hopes to fly to

8896-467: The aluminum spelling in his American Dictionary of the English Language . In the 1830s, the -um spelling gained usage in the United States; by the 1860s, it had become the more common spelling there outside science. In 1892, Hall used the -um spelling in his advertising handbill for his new electrolytic method of producing the metal, despite his constant use of the -ium spelling in all

9035-423: The chemical formula Al 2 O 3 , commonly called alumina . It can be found in nature in the mineral corundum , α-alumina; there is also a γ-alumina phase. Its crystalline form, corundum, is very hard ( Mohs hardness 9), has a high melting point of 2,045 °C (3,713 °F), has very low volatility, is chemically inert, and a good electrical insulator, it is often used in abrasives (such as toothpaste), as

9174-634: The free metal . It is obtained industrially by mining bauxite , a sedimentary rock rich in aluminium minerals. The discovery of aluminium was announced in 1825 by Danish physicist Hans Christian Ørsted . The first industrial production of aluminium was initiated by French chemist Henri Étienne Sainte-Claire Deville in 1856. Aluminium became much more available to the public with the Hall–Héroult process developed independently by French engineer Paul Héroult and American engineer Charles Martin Hall in 1886, and

9313-542: The interstellar gas ; if the original Al were still present, gamma ray maps of the Milky Way would be brighter. Overall, the Earth is about 1.59% aluminium by mass (seventh in abundance by mass). Aluminium occurs in greater proportion in the Earth's crust than in the universe at large. This is because aluminium easily forms the oxide and becomes bound into rocks and stays in the Earth's crust , while less reactive metals sink to

9452-465: The 5th century BCE. The ancients are known to have used alum as a dyeing mordant and for city defense. After the Crusades , alum, an indispensable good in the European fabric industry, was a subject of international commerce; it was imported to Europe from the eastern Mediterranean until the mid-15th century. The nature of alum remained unknown. Around 1530, Swiss physician Paracelsus suggested alum

9591-472: The Al–Zn–Mg class. Aluminium has a high chemical affinity to oxygen, which renders it suitable for use as a reducing agent in the thermite reaction. A fine powder of aluminium reacts explosively on contact with liquid oxygen ; under normal conditions, however, aluminium forms a thin oxide layer (~5 nm at room temperature) that protects the metal from further corrosion by oxygen, water, or dilute acid,

9730-468: The Irish Aviation Authority. As supply increases, this sort of differentiation by brand is an important criteria for the future success of low-cost carriers, since many experts believe price competition alone is not enough, given the number of carriers. As the number of low-cost carriers has grown, these airlines have begun to compete with one another in addition to the traditional carriers. In

9869-604: The Middle East and 12% within Africa. A long-haul low-cost operation would be harder to differentiate from a conventional airline as there are few cost savings possibilities, while the seat costs would have to be lower than the competition. Long-haul aircraft scheduling is often determined by time zone constraints, like leaving the US East Coast in the evening and arriving in Europe

10008-674: The UK, Basic-Fit in Benelux and France, and McFit in Germany. In the Netherlands and other European countries, a no frills filling station refers to unattended filling stations consisting solely of self-service pumps that only support pay at the pump . They do not include any other facilities on-site, and service is provided via a phone line. If there is a problem, drivers are to call a hotline using an on-site telephone for assistance. Notable chains includes Dutch chains Tango , Q8 Easy , TinQ , Firezone , Esso Express & Shell Express , and

10147-399: The US, airlines have responded by introducing variations to the model. In Europe, the emphasis has remained on reducing costs and no-frills service. A secondary term ultra low-cost carrier ( ULCC ) has been used to differentiate some low-cost airlines whose model deviates further from that of a standard low-cost carrier, with ultra low-cost carriers having minimal inclusions in the fare and

10286-418: The United States dollar, and alumina prices. The BRIC countries' combined share in primary production and primary consumption grew substantially in the first decade of the 21st century. China is accumulating an especially large share of the world's production thanks to an abundance of resources, cheap energy, and governmental stimuli; it also increased its consumption share from 2% in 1972 to 40% in 2010. In

10425-510: The United States, Western Europe, and Japan, most aluminium was consumed in transportation, engineering, construction, and packaging. In 2021, prices for industrial metals such as aluminium have soared to near-record levels as energy shortages in China drive up costs for electricity. The names aluminium and aluminum are derived from the word alumine , an obsolete term for alumina , the primary naturally occurring oxide of aluminium . Alumine

10564-440: The advertised base prices are very low, charges and taxes are typically not mentioned. With some airlines, some flights are advertised as free (plus applicable taxes, fees and charges). Depending on the airline, perhaps as many (or as few) as ten percent of the seats on any flight are offered at the lowest price and are the first to sell. The prices steadily rise thereafter to a point where they can be comparable or more expensive than

10703-673: The aircraft (turnaround) in shorter time periods and do not wait for late passengers, allowing maximum utilization of aircraft. Low-cost carriers generate ancillary revenue from a variety of activities, such as à la carte features and commission-based products. Some airlines may charge a fee for a pillow or blanket or for carry-on baggage. In Europe, it is common for each and every convenience and service to have an additional charge. Low-cost carriers intend to be low-cost, so in many cases employees work multiple roles. At some airlines flight attendants also work as gate agents or assume other roles, thereby limiting personnel costs. Southwest Airlines

10842-676: The airline can avoid responsibility for passengers' connections in the event of a delay. Low-cost carriers often have a sparse schedule with one flight per day and route, so it would be hard to find an alternative for a missed connection. Modern US-based low-cost carriers generally transfer baggage for continuing flights, as well as transferring baggage to other airlines. Many airlines opt to have passengers board via stairs, since jetways generally cost more to lease. Often, low-cost carriers fly to smaller, less congested secondary airports and/or fly to airports during off-peak hours to avoid air traffic delays and take advantage of lower landing fees . This

10981-573: The airlines only in the long term). During this period, most passengers were business travellers who paid high fares that covered these costs. After deregulation, which led to lower fares, many airlines remained bound to these salary agreements and pensions, whereas new low-cost carriers employed new staff with lower salaries, especially for cabin crew, keeping personnel costs low and allowing for competitive fares. In some cases airlines have gone bankrupt (e.g., Alitalia , Sabena , and Swissair ), and new airlines replaced them. Traditional carriers followed

11120-578: The aluminium atoms have tetrahedral four-coordination and the other half have trigonal bipyramidal five-coordination. Four pnictides – aluminium nitride (AlN), aluminium phosphide (AlP), aluminium arsenide (AlAs), and aluminium antimonide (AlSb) – are known. They are all III-V semiconductors isoelectronic to silicon and germanium , all of which but AlN have the zinc blende structure. All four can be made by high-temperature (and possibly high-pressure) direct reaction of their component elements. Aluminium alloys well with most other metals (with

11259-644: The availability of next generation planes that make long haul routes more feasible for LCCs. In the past, low-cost carriers tended to operate older aircraft purchased second-hand, such as the McDonnell Douglas DC-9 and older models of the Boeing 737 . Since 2000, fleets generally consist of the newest aircraft, commonly the Airbus A320 family and Boeing 737. Although buying new aircraft is usually more expensive than second-hand, new planes are cheaper to operate in

11398-436: The characteristic physical properties of a post-transition metal, with longer-than-expected interatomic distances. Furthermore, as Al is a small and highly charged cation, it is strongly polarizing and bonding in aluminium compounds tends towards covalency ; this behavior is similar to that of beryllium (Be ), and the two display an example of a diagonal relationship . The underlying core under aluminium's valence shell

11537-592: The continental US and Europe . In April 2006, the industry magazine Airline Business analysed the potential for low-cost long-haul service and concluded that a number of Asian carriers, including AirAsia, were closest to making such a model work. On 26 October 2006, Oasis Hong Kong Airlines started flying from Hong Kong to London-Gatwick . The lowest prices for flights between Hong Kong to London could be as low at £75 (approximately US$ 150) per leg (not including taxes and other charges) for economy class and £470 (approximately US$ 940) per leg for business class for

11676-419: The coordination numbers are lower. The other trihalides are dimeric or polymeric with tetrahedral four-coordinate aluminium centers. Aluminium trichloride (AlCl 3 ) has a layered polymeric structure below its melting point of 192.4 °C (378 °F) but transforms on melting to Al 2 Cl 6 dimers. At higher temperatures those increasingly dissociate into trigonal planar AlCl 3 monomers similar to

11815-428: The core. In the Earth's crust, aluminium is the most abundant metallic element (8.23% by mass ) and the third most abundant of all elements (after oxygen and silicon). A large number of silicates in the Earth's crust contain aluminium. In contrast, the Earth's mantle is only 2.38% aluminium by mass. Aluminium also occurs in seawater at a concentration of 2 μg/kg. Because of its strong affinity for oxygen, aluminium

11954-474: The decay of Al was responsible for the melting and differentiation of some asteroids after their formation 4.55 billion years ago. The remaining isotopes of aluminium, with mass numbers ranging from 21 to 43, all have half-lives well under an hour. Three metastable states are known, all with half-lives under a minute. An aluminium atom has 13 electrons, arranged in an electron configuration of [ Ne ] 3s 3p , with three electrons beyond

12093-568: The early 1970s, Plymouth, Ford and Chevrolet had switched to all V-8 engine/automatic transmission powertrains for the full-sized model lines. With customers turning more to volume models that were better trimmed, upholstered and equipped (even with price a primary consideration), the Big Three dropped their Spartan-trimmed price-leading models, such as the Chevrolet Biscayne and Ford Custom, or relegated them completely to fleet sales only. During

12232-670: The end of Skytrain . In late 2007, Cebu Pacific , the Philippines ' largest low-cost carrier, announced non-stop flights from the Philippines to the United States West Coast and other US cities from mid-2009. The airline also intends to launch low-cost service to Middle East , where around a million Filipinos are based, and in Europe. Flights to Dubai — its first long-haul destination — started in 2013. As of September 2024, it operates flights to Dubai daily, to Sydney four times

12371-545: The end of 2009, while seat capacity reached nearly 1.7 billion in 2018. LCCs accounted for 33% of intra-regional seat capacity in 2018 with 1.564 billion, up from 25% in 2008 with 753 million, and 13% of seat capacity between regions with 101 million, up from 6% in 2009 with 26 million. In 2018, penetration rate was 41% of seats within Europe, 36% within Latin America, 32% within North America, 29% within Asia Pacific, 17% within

12510-399: The environment, no living organism is known to metabolize aluminium salts , but this aluminium is well tolerated by plants and animals. Because of the abundance of these salts, the potential for a biological role for them is of interest, and studies are ongoing. Of aluminium isotopes, only Al is stable. This situation is common for elements with an odd atomic number. It is

12649-478: The exception of most alkali metals and group 13 metals) and over 150 intermetallics with other metals are known. Preparation involves heating fixed metals together in certain proportion, followed by gradual cooling and annealing . Bonding in them is predominantly metallic and the crystal structure primarily depends on efficiency of packing. There are few compounds with lower oxidation states. A few aluminium(I) compounds exist: AlF, AlCl, AlBr, and AlI exist in

12788-520: The fact that its nuclei are much lighter, while difference in the unit cell size does not compensate for this difference. The only lighter metals are the metals of groups 1 and 2 , which apart from beryllium and magnesium are too reactive for structural use (and beryllium is very toxic). Aluminium is not as strong or stiff as steel, but the low density makes up for this in the aerospace industry and for many other applications where light weight and relatively high strength are crucial. Pure aluminium

12927-561: The following morning, and the longer flight times mean there is less scope to increase aircraft utilization as in short-haul. The business model is financially risky , and many companies have entered bankruptcy , like Laker Airways . In 2004, Irish Aer Lingus maintains a full service on transatlantic flights while it lowered its prices to compete with Ryanair on short haul. Late in 2004, Oasis Hong Kong Airlines offered London to Hong Kong flights from £199, and Canadian Zoom Airlines started selling transatlantic flights between

13066-636: The full range of engines and transmissions, including those that were performance-oriented, unlike the later no-frills models that had restricted performance options. Additionally, marketing brochures typically extolled the virtues of these economy models, pointing out such features as durable and easy-to-care for upholstery with wide color availability, beauty in styling despite minimal exterior trim adornment, and features shared with more luxurious models such as suspension and ride quality, engine and transmission availability, and standard safety and convenience features—all available even for budget-conscious buyers. By

13205-730: The gas phase after explosion and in stellar absorption spectra. More thoroughly investigated are compounds of the formula R 4 Al 2 which contain an Al–Al bond and where R is a large organic ligand . A variety of compounds of empirical formula AlR 3 and AlR 1.5 Cl 1.5 exist. The aluminium trialkyls and triaryls are reactive, volatile, and colorless liquids or low-melting solids. They catch fire spontaneously in air and react with water, thus necessitating precautions when handling them. They often form dimers, unlike their boron analogues, but this tendency diminishes for branched-chain alkyls (e.g. Pr , Bu , Me 3 CCH 2 ); for example, triisobutylaluminium exists as an equilibrium mixture of

13344-453: The gaseous phase when the respective trihalide is heated with aluminium, and at cryogenic temperatures. A stable derivative of aluminium monoiodide is the cyclic adduct formed with triethylamine , Al 4 I 4 (NEt 3 ) 4 . Al 2 O and Al 2 S also exist but are very unstable. Very simple aluminium(II) compounds are invoked or observed in the reactions of Al metal with oxidants. For example, aluminium monoxide , AlO, has been detected in

13483-527: The gasoline crisis of the 1970s, many American automakers began offering no-frills models on their compact lines of cars (such as the Ford Pinto MPG , and Plymouth Duster "Feather Duster" ). As before, these models usually had spartan trim (vinyl seats with rubber floor covering); fewer convenience items than the more expensive models (e.g., no cigarette lighter); lighter-weight components (such as aluminum on various engine, body and suspension components); and

13622-401: The ground by using the larger aircraft services of established charter airlines. Among this group were the virtual airlines ; Direct Air , PeoplExpress , Western , and those that never began service such as JetAmerica . In Japan, low-cost airlines made major inroads into the market in 2012 when Peach , Jetstar Japan and AirAsia Japan began operations, each with financial sponsorship by

13761-646: The halides, nitrate , and sulfate . For similar reasons, anhydrous aluminium salts cannot be made by heating their "hydrates": hydrated aluminium chloride is in fact not AlCl 3 ·6H 2 O but [Al(H 2 O) 6 ]Cl 3 , and the Al–O bonds are so strong that heating is not sufficient to break them and form Al–Cl bonds instead: All four trihalides are well known. Unlike the structures of the three heavier trihalides, aluminium fluoride (AlF 3 ) features six-coordinate aluminium, which explains its involatility and insolubility as well as high heat of formation . Each aluminium atom

13900-487: The late 1960s, a vast majority of all price-leading models were built and sold with V-8 engines and automatic transmission, as consumer needs were changing, and were even being built and sold with luxury comfort and convenience features once seen only on the higher-priced model lines, including air conditioning and power steering. Only a small handful of base model vehicles were sold with the basic six-cylinder/three-speed manual transmission powertrain, without optional extras. By

14039-783: The legacy carriers will force Long-haul LCCS to lose too much money and will continue to dominate. While Asian carriers like AirAsia X, Scoot , Cebu Pacific and Jetstar Airways are successful, the October 2018 demise of Primera Air and its $ 99 transatlantic flights illustrates the difficulties of the model, as the US World Airways will be relaunched in 2019. Norse Atlantic Airways was founded in 2021 and commenced operations in 2022, operating transatlantic flights as well as flights to Thailand beginning in 2023. Aluminum Aluminium (or aluminum in North American English )

14178-712: The less complex aircraft fleets and route networks with which these new carriers began operations, in addition to their reduced labor costs. To combat the new round of low-cost and start-up entrants into the very competitive and deregulated United States airline industry, the mainline major carriers and network legacy carriers strategically developed no-frills divisions within the main airlines brand and corporate structures. Among these were Continental Lite , Delta Express , MetroJet , Shuttle by United , Song , and Ted . However, most of these "airlines within an airline" were short-lived and quickly disposed-of when economic rationalization or competitive pressures subsided. Taking

14317-581: The line between a hotel and a hostel is blurred due to the removal of amenities. Notable no-frills chains include Motel 6 , Econo Lodge , Tune Hotels , Ibis Budget , HotelF1 , easyHotel and Zip by Premier Inn . Features of no-frills hotels rooms are that themselves are smaller and more spartan in trim. Examples and cases included with Zip rooms are twice as small (8.5 m) as standard Premier Inn rooms. (20 m), beds in Econo Lodge are put on boxes, so to make cleaning easier and with many Ibis Budget hotels,

14456-485: The long run since they are extremely efficient in terms of fuel, training, maintenance, and crew costs per passenger. In 2013, ch-aviation published a study about the fleet strategy of low-cost carriers. They stated that major LCCs that order aircraft in large numbers get large discounts for doing so, and due to this they can sell their aircraft just a few years after delivery at a price high enough to keep their operating costs relatively low. Aircraft often operate with

14595-666: The low-cost carriers by enabling web check-in, encouraging machine check-in at the airport, and generally reducing ground personnel cost. The number of crew members follow international conventions that require one flight attendant per 50 passenger seats and two pilots. However, carriers can save money by reducing the amount of ground crew. Carriers hire pilots through third-party agencies based in low-tax countries without benefits for sick pay, pensions or health insurance. Traditional carriers have also started to try this, including starting their own low-tax agencies. These agencies can easily find less experienced co-pilots and cabin crew, as

14734-433: The low-pressure polymerization of ethene and propene . There are also some heterocyclic and cluster organoaluminium compounds involving Al–N bonds. The industrially most important aluminium hydride is lithium aluminium hydride (LiAlH 4 ), which is used as a reducing agent in organic chemistry . It can be produced from lithium hydride and aluminium trichloride . The simplest hydride, aluminium hydride or alane,

14873-508: The mass production of aluminium led to its extensive use in industry and everyday life. In the First and Second World Wars, aluminium was a crucial strategic resource for aviation . In 1954, aluminium became the most produced non-ferrous metal , surpassing copper . In the 21st century, most aluminium was consumed in transportation, engineering, construction, and packaging in the United States, Western Europe, and Japan. Despite its prevalence in

15012-529: The metal remained rare; its cost exceeded that of gold. The first industrial production of aluminium was established in 1856 by French chemist Henri Etienne Sainte-Claire Deville and companions. Deville had discovered that aluminium trichloride could be reduced by sodium, which was more convenient and less expensive than potassium, which Wöhler had used. Even then, aluminium was still not of great purity and produced aluminium differed in properties by sample. Because of its electricity-conducting capacity, aluminium

15151-628: The metal to be isolated from alum was alumium , which Davy suggested in an 1808 article on his electrochemical research, published in Philosophical Transactions of the Royal Society . It appeared that the name was created from the English word alum and the Latin suffix -ium ; but it was customary then to give elements names originating in Latin, so this name was not adopted universally. This name

15290-465: The metal with many uses at the time. During World War I , major governments demanded large shipments of aluminium for light strong airframes; during World War II , demand by major governments for aviation was even higher. By the mid-20th century, aluminium had become a part of everyday life and an essential component of housewares. In 1954, production of aluminium surpassed that of copper , historically second in production only to iron, making it

15429-486: The metal. Almost all metallic aluminium is produced from the ore bauxite (AlO x (OH) 3–2 x ). Bauxite occurs as a weathering product of low iron and silica bedrock in tropical climatic conditions. In 2017, most bauxite was mined in Australia, China, Guinea, and India. The history of aluminium has been shaped by usage of alum . The first written record of alum, made by Greek historian Herodotus , dates back to

15568-485: The monomer and dimer. These dimers, such as trimethylaluminium (Al 2 Me 6 ), usually feature tetrahedral Al centers formed by dimerization with some alkyl group bridging between both aluminium atoms. They are hard acids and react readily with ligands, forming adducts. In industry, they are mostly used in alkene insertion reactions, as discovered by Karl Ziegler , most importantly in "growth reactions" that form long-chain unbranched primary alkenes and alcohols, and in

15707-506: The most produced non-ferrous metal . During the mid-20th century, aluminium emerged as a civil engineering material, with building applications in both basic construction and interior finish work, and increasingly being used in military engineering, for both airplanes and land armor vehicle engines. Earth's first artificial satellite , launched in 1957, consisted of two separate aluminium semi-spheres joined and all subsequent space vehicles have used aluminium to some extent. The aluminium can

15846-599: The next decade, the -um spelling dominated American usage. In 1925, the American Chemical Society adopted this spelling. The International Union of Pure and Applied Chemistry (IUPAC) adopted aluminium as the standard international name for the element in 1990. In 1993, they recognized aluminum as an acceptable variant; the most recent 2005 edition of the IUPAC nomenclature of inorganic chemistry also acknowledges this spelling. IUPAC official publications use

15985-429: The only primordial aluminium isotope, i.e. the only one that has existed on Earth in its current form since the formation of the planet. It is therefore a mononuclidic element and its standard atomic weight is virtually the same as that of the isotope. This makes aluminium very useful in nuclear magnetic resonance (NMR), as its single stable isotope has a high NMR sensitivity. The standard atomic weight of aluminium

16124-407: The oxidation state 3+. The coordination number of such compounds varies, but generally Al is either six- or four-coordinate. Almost all compounds of aluminium(III) are colorless. In aqueous solution, Al exists as the hexaaqua cation [Al(H 2 O) 6 ] , which has an approximate K a of 10 . Such solutions are acidic as this cation can act as a proton donor and progressively hydrolyze until

16263-460: The patents he filed between 1886 and 1903. It is unknown whether this spelling was introduced by mistake or intentionally, but Hall preferred aluminum since its introduction because it resembled platinum , the name of a prestigious metal. By 1890, both spellings had been common in the United States, the -ium spelling being slightly more common; by 1895, the situation had reversed; by 1900, aluminum had become twice as common as aluminium ; in

16402-404: The planet. However, minute traces of Al are produced from argon in the atmosphere by spallation caused by cosmic ray protons. The ratio of Al to Be has been used for radiodating of geological processes over 10 to 10  year time scales, in particular transport, deposition, sediment storage, burial times, and erosion. Most meteorite scientists believe that the energy released by

16541-424: The post– Vietnam War era did this business model escalate. Through various ticket consolidators, charter airlines , and innovators in lower-frills flying, such as Channel Airways and Court Line , the traveling public had been conditioned to want to travel to new and increasingly further away and exotic locations on vacation, rather than short-haul trips to nearby beach resorts. The world's first low-cost airline

16680-868: The profession is popular, but there are problems for low-cost carriers to recruit and keep captains who have to be experienced. At IATA , a LCC operation is defined as including the following characteristics, at least to some degree: While low-cost airlines differ in service offerings, by definition they feature most of the following: Not every low-cost carrier implements all of the above points. For example, some try to differentiate themselves with allocated seating, while others operate more than one aircraft type, still others have relatively high operating costs but lower fares. JetBlue , for instance, has in-flight entertainment in every passenger seat. Other airlines are limited on what points they can implement based on local laws. For example, Irish low cost airlines cannot remove window blinds from its aircraft, as they are required by

16819-417: The reception is only opened at limited hours. Most no frills hotels don't have door keys , instead they use either inexpensive swipe-keys or digital door locks . Many of them have no pictures on the walls, baths in the bathrooms or excessive furniture like minibars, fridges or dressing tables. Bedding is limited to pillows and duvets . Some like Tune and easyHotel even go as far as putting advertisements on

16958-423: The respective hydrogen chalcogenide . As aluminium is a small atom relative to these chalcogens, these have four-coordinate tetrahedral aluminium with various polymorphs having structures related to wurtzite , with two-thirds of the possible metal sites occupied either in an orderly (α) or random (β) fashion; the sulfide also has a γ form related to γ-alumina, and an unusual high-temperature hexagonal form where half

17097-542: The room is only done when the guest leaves, and toiletries and supplement towels. The Finnish hotel chain Omenahotelli lacks reception. Room bookings are handled online only. Instead of a physical key, hotel customers receive a digital door code. Omenahotelli guests usually spend their entire hotel stay without meeting any hotel employees. No-frills holidays are holidays which, like no-frills airlines, do not include unnecessary services such as: Such holidays usually have

17236-494: The same route. From 28 June 2007, a second long-haul route to Vancouver, British Columbia , was started. The company ceased operations on 9 April 2008, after over a billion Hong Kong dollars in losses. On 2 November 2007, AirAsia X , a subsidiary of AirAsia and Virgin Group flew its inaugural flight from Kuala Lumpur , Malaysia, to Gold Coast , Australia. AirAsia X claims that it is the first true low-cost long-haul carrier since

17375-485: The scale of the economies. However, the need to exploit lower-grade poorer quality deposits and the use of fast increasing input costs (above all, energy) increased the net cost of aluminium; the real price began to grow in the 1970s with the rise of energy cost. Production moved from the industrialized countries to countries where production was cheaper. Production costs in the late 20th century changed because of advances in technology, lower energy prices, exchange rates of

17514-403: The second half of 2013 after Boeing resumed deliveries following extensive problems and delays. It served direct routes from the United States ( Los Angeles , Fort Lauderdale , New York City , Oakland-San Francisco , Boston and Orlando ) into Scandinavia ( Oslo , Stockholm , Copenhagen ). In January 2021 Norwegian announced the immediate cessation of their long-haul operations, along with

17653-408: The structure of BCl 3 . Aluminium tribromide and aluminium triiodide form Al 2 X 6 dimers in all three phases and hence do not show such significant changes of properties upon phase change. These materials are prepared by treating aluminium with the halogen. The aluminium trihalides form many addition compounds or complexes; their Lewis acidic nature makes them useful as catalysts for

17792-536: The two therefore look similar. Aluminium is also good at reflecting solar radiation , although prolonged exposure to sunlight in air adds wear to the surface of the metal; this may be prevented if aluminium is anodized , which adds a protective layer of oxide on the surface. The density of aluminium is 2.70 g/cm , about 1/3 that of steel, much lower than other commonly encountered metals, making aluminium parts easily identifiable through their lightness. Aluminium's low density compared to most other metals arises from

17931-449: The walls and in case of Zip some rooms even having no windows, instead having a sunlight-powered light box . Like no frills airlines which charge people for seat reservations and food, no frills hotels themselves charge extra for any superfluous extras like non-basic TV channels, breakfasts; which themselves are just limited to a continental style , tea-and-coffee making facilities, Wi-Fi internet , daily maid service ; normally cleaning

18070-523: Was Bill Clinton , later US President. The first airline offering no-frills transatlantic service was Freddie Laker 's Laker Airways , which operated its famous "Skytrain" service between London and New York City during the late 1970s. The service was suspended after Laker's competitors, British Airways and Pan Am , were able to price Skytrain out of the market. In the United States, airline carriers such as Midway Airlines and America West Airlines , which commenced operations after 1978, soon realized

18209-494: Was Pacific Southwest Airlines , which started intrastate flights connecting Southern and Northern California on 6 May 1949. PSA's light-hearted atmosphere and efficient operations were a runaway success early on, and inspired a number of low-cost start-ups across the United States, beginning in the mid-1960s. Herb Kelleher studied the success of PSA, and copied their culture closely when he established Southwest Airlines in 1971. The first airline to offer cheaper transatlantic fares

18348-492: Was Icelandic airline Loftleiðir in 1964, often referred to as "the Hippie Airline". Many young Americans travelled to Europe after graduation, to experience the "old-world culture", and they were more concerned with getting there cheaply than comfortably or even exactly on time. Loftleiðir were not famous for speed or punctuality, but flying with the company became a sort of rite of passage for those young "hippies", one of whom

18487-461: Was a salt of an earth of alum. In 1595, German doctor and chemist Andreas Libavius experimentally confirmed this. In 1722, German chemist Friedrich Hoffmann announced his belief that the base of alum was a distinct earth. In 1754, German chemist Andreas Sigismund Marggraf synthesized alumina by boiling clay in sulfuric acid and subsequently adding potash . Attempts to produce aluminium date back to 1760. The first successful attempt, however,

18626-485: Was borrowed from French, which in turn derived it from alumen , the classical Latin name for alum , the mineral from which it was collected. The Latin word alumen stems from the Proto-Indo-European root *alu- meaning "bitter" or "beer". British chemist Humphry Davy , who performed a number of experiments aimed to isolate the metal, is credited as the person who named the element. The first name proposed for

18765-422: Was completed in 1824 by Danish physicist and chemist Hans Christian Ørsted . He reacted anhydrous aluminium chloride with potassium amalgam , yielding a lump of metal looking similar to tin. He presented his results and demonstrated a sample of the new metal in 1825. In 1827, German chemist Friedrich Wöhler repeated Ørsted's experiments but did not identify any aluminium. (The reason for this inconsistency

18904-492: Was criticized by contemporary chemists from France, Germany, and Sweden, who insisted the metal should be named for the oxide, alumina, from which it would be isolated. The English name alum does not come directly from Latin, whereas alumine / alumina obviously comes from the Latin word alumen (upon declension , alumen changes to alumin- ). One example was Essai sur la Nomenclature chimique (July 1811), written in French by

19043-418: Was invented in 1956 and employed as a storage for drinks in 1958. Throughout the 20th century, the production of aluminium rose rapidly: while the world production of aluminium in 1900 was 6,800 metric tons, the annual production first exceeded 100,000 metric tons in 1916; 1,000,000 tons in 1941; 10,000,000 tons in 1971. In the 1970s, the increased demand for aluminium made it an exchange commodity; it entered

19182-433: Was only discovered in 1921.) He conducted a similar experiment in the same year by mixing anhydrous aluminium chloride with potassium and produced a powder of aluminium. In 1845, he was able to produce small pieces of the metal and described some physical properties of this metal. For many years thereafter, Wöhler was credited as the discoverer of aluminium. As Wöhler's method could not yield great quantities of aluminium,

19321-571: Was used as the cap of the Washington Monument , completed in 1885. The tallest building in the world at the time, the non-corroding metal cap was intended to serve as a lightning rod peak. The first industrial large-scale production method was independently developed in 1886 by French engineer Paul Héroult and American engineer Charles Martin Hall ; it is now known as the Hall–Héroult process . The Hall–Héroult process converts alumina into metal. Austrian chemist Carl Joseph Bayer discovered
