An IATA airport code , also known as an IATA location identifier , IATA station code , or simply a location identifier , is a three-letter geocode designating many airports and metropolitan areas around the world, defined by the International Air Transport Association (IATA). The characters prominently displayed on baggage tags attached at airport check-in desks are an example of a way these codes are used.
52-854: Telluride Regional Airport ( IATA : TEX , ICAO : KTEX , FAA LID : TEX ) is a public airport six miles west of Telluride , in San Miguel County , Colorado , United States. It is owned by the Telluride Regional Airport Authority. At an elevation of 9,078 feet (2767 m) above sea level, it was the highest commercial airport in North America with scheduled passenger flights when Great Lakes Airlines resumed scheduled passenger service in December 2016; however, those flights ceased in March 2018. In August 2018, commercial service returned with
104-786: A few months later. Monarch Airlines was serving the airport in 1987 with de Havilland Canada DHC-6 Twin Otter turboprop flights from Aspen, Crested Butte, Grand Junction and Vail with the latter service being flown from the Eagle County Regional Airport . Rocky Mountain Airways operating as Continental Express on behalf of Continental Airlines served Telluride from 1986 through mid-1991 flying 19-passenger Beechcraft 1900C and 50-passenger de Havilland Canada DHC-7 Dash 7 turboprops nonstop to Denver (DEN). Some flights stopped in Aspen (ASE) during

By 1989, Britt was operating all Continental Express flights from Cleveland with Embraer EMB-120 Brasilia propjets. In 1991, Britt Airways began operating Continental Express service formerly flown by Rocky Mountain Airways from Denver (DEN). According to
208-550: A new airport is built, replacing the old one, leaving the city's new "major" airport (or the only remaining airport) code to no longer correspond with the city's name. The original airport in Nashville, Tennessee, was built in 1936 as part of the Works Progress Administration and called Berry Field with the designation, BNA. A new facility known as Nashville International Airport was built in 1987 but still uses BNA. This

According to the October 29, 1978 Britt Airways system timetable, commuter flights for Allegheny were operated by Britt from the airline's small hub located at Chicago O'Hare Airport (ORD) with service to Bloomington, IN , Danville, IL , Indianapolis, IN , Muncie, IN and Terre Haute, IN , all former Lake Central routes that were acquired by Allegheny. In 1979, Britt
364-499: Is GSN and its IATA code is SPN, and some coincide with IATA codes of non-U.S. airports. Canada's unusual codes—which bear little to no similarity with any conventional abbreviation to the city's name—such as YUL in Montréal , and YYZ in Toronto , originated from the two-letter codes used to identify weather reporting stations in the 1930s. The letters preceding the two-letter code follow
416-600: Is available. However, many railway administrations have their own list of codes for their stations, such as the list of Amtrak station codes . Airport codes arose out of the convenience that the practice brought pilots for location identification in the 1930s. Initially, pilots in the United States used the two-letter code from the National Weather Service (NWS) for identifying cities. This system became unmanageable for cities and towns without an NWS identifier, and
468-465: Is designed in part to allow larger aircraft to utilize the airport. Telluride Regional Airport is the destination in the "Telluride Landing" mission supplied with Microsoft Flight Simulator X . The player must land a Bombardier Learjet 45 with passengers on board. Part of an episode of The Grand Tour was filmed at the airport, in which the presenters tried to get some Jaguar Cars up to 100 mph (160 km/h) and then stop before going over
520-518: Is different from the name in English, yet the airport code represents only the English name. Examples include: Due to scarcity of codes, some airports are given codes with letters not found in their names: The use of 'X' as a filler letter is a practice to create three-letter identifiers when more straightforward options were unavailable: Some airports in the United States retained their NWS ( National Weather Service ) codes and simply appended an X at
572-513: Is in conjunction to rules aimed to avoid confusion that seem to apply in the United States, which state that "the first and second letters or second and third letters of an identifier may not be duplicated with less than 200 nautical miles separation." Thus, Washington, D.C. area's three airports all have radically different codes: IAD for Washington–Dulles , DCA for Washington–Reagan (District of Columbia Airport), and BWI for Baltimore (Baltimore–Washington International, formerly BAL). Since HOU

#1733122288662624-532: Is not followed outside the United States: In addition, since three letter codes starting with Q are widely used in radio communication, cities whose name begins with "Q" also had to find alternate codes, as in the case of: IATA codes should not be confused with the FAA identifiers of U.S. airports. Most FAA identifiers agree with the corresponding IATA codes, but some do not, such as Saipan , whose FAA identifier
676-435: Is one of the few regional jet airliners in service capable of operating at such high field elevations as TEX. Telluride Regional Airport covers 542 acres (219 ha) and has one runway , 9/27, 7,111 by 100 feet (2,167 by 30 m). The runway is on a plateau and still dips slightly in the center, although the dip was more pronounced prior to a renovation in 2009. It can be a challenging but beautiful approach for pilots. In

The code BKK was originally assigned to Bangkok–Don Mueang and was later transferred to Suvarnabhumi Airport , while the former adopted DMK. The code ISK was originally assigned to Gandhinagar Airport (Nashik's old airport) and later on transferred to Ozar Airport (Nashik's current airport). Shanghai–Hongqiao retained
780-561: The Canadian transcontinental railroads were built, each station was assigned its own two-letter Morse code : When the Canadian government established airports, it used the existing railway codes for them as well. If the airport had a weather station, authorities added a "Y" to the front of the code, meaning "Yes" to indicate it had a weather station or some other letter to indicate it did not. When international codes were created in cooperation with

Between April 7 and November 4, 2009, the Telluride runway was closed for a $ 24 million runway renovation. The west end of the runway was lowered 30 feet, and the east end 14 ft. The material removed was placed in the center, removing
884-627: The Official Airline Guide (OAG), in 1989 Britt was the primary Continental Express carrier at Houston Intercontinental operating ATR-42 and Embraer EMB-120 Brasilia propjet aircraft on feeder services on behalf of Continental. By 1991, the airline was the primary Continental Express carrier at Newark as well operating ATR-42 and Embraer EMB-120 Brasilia aircraft according to the OAG . Beginning in November, 1987, Continental Airlines established

Great Lakes flew Beechcraft 1900Ds nonstop to Denver and changed over to operating under their own identity in early 2002 after the carrier lost its designation as a United Express code sharing air carrier. Service to Telluride continued until September 16, 2014. Great Lakes returned to the airport in December 2016 with flights to Denver and later Phoenix and Los Angeles with one stop en route; however, all service ended once again on March 30, 2018, when Great Lakes ceased all of their operations with turboprop aircraft.

1248-817: The Phoenix flights began operating as America West Express on behalf of America West Airlines . Embraer EMB-120 Brasilia and de Havilland Canada DHC-8 Dash 8 aircraft were periodically added to the flight schedules. The Albuquerque flights ended after the 1992/1993 ski season and the Denver flights ended in early 1998 being replaced by Great Lakes Airlines. The Phoenix flights were upgraded to operate with de Havilland Canada DHC-8 Dash 8 turboprops in 1998 and then changed over to operate as US Airways Express in 2007 when America West Airlines and US Airways merged. All service by Mesa Airlines ended on April 4, 2011. Great Lakes Airlines began service to Telluride in mid 1998 by taking over

From late 1985 through late 1986, Britt operated code sharing flight services for Piedmont Airlines (1948-1989) as a Piedmont Commuter System air carrier from the Dayton International Airport (DAY) in Ohio where Piedmont was operating a hub at the time. Frank Lorenzo 's holding company, Texas Air Corporation , acquired People Express later in 1985. Texas Air Corporation had previously acquired Continental Airlines (CO) and merged Texas International Airlines (predecessor to Texas Air) and CO under
1352-466: The U.S. For example, several airports in Alaska have scheduled commercial service, such as Stebbins and Nanwalek , which use FAA codes instead of ICAO codes. Thus, neither system completely includes all airports with scheduled service. Some airports are identified in colloquial speech by their IATA code. Examples include LAX and JFK . Britt Airways Britt Airways was a regional airline in
1404-481: The United States, because "Y" was seldom used in the United States, Canada simply used the weather station codes for its airports, changing the "Y" to a "Z" if it conflicted with an airport code already in use. The result is that most major Canadian airport codes start with "Y" followed by two letters in the city's name (for example, YOW for O tta w a , YWG for W innipe g , YYC for C algar y , or YVR for V ancouve r ), whereas other Canadian airports append
1456-521: The airline had expanded its hub operation at Chicago O'Hare with new service to Decatur, IL , Mattoon, IL / Charleston, IL , and South Bend, IN , and had also expanded its fleet with the addition of larger Fairchild Hiller FH-227 turboprops. In 1981, Britt began operating as an independent air carrier from a major hub located at Chicago O'Hare Airport (ORD) and also from smaller hubs located at St. Louis Lambert International Airport (STL) and Indianapolis International Airport (IND). By early 1985,

For instance: Or using a code for the city in one of the major airports and then assigning another code to another airport: When different cities with the same name each have an airport, they need to be assigned different codes. Examples include: Sometimes,

In rare cases, the code comes from the airport's unofficial name, such as Kahului Airport 's OGG (for local aviation pioneer Jimmy H ogg ). In large metropolitan areas, airport codes are often named after

IATA airport code The assignment of these codes is governed by IATA Resolution 763, and it is administered by the IATA's headquarters in Montreal , Canada. The codes are published semi-annually in the IATA Airline Coding Directory. IATA provides codes for airport handling entities, and for certain railway stations. Alphabetical lists of airports sorted by IATA code are available. A list of railway station codes , shared in agreements between airlines and rail lines such as Amtrak , SNCF , and Deutsche Bahn ,

The opposite was true for Berlin : the airport Berlin–Tegel used the code TXL, while its smaller counterpart Berlin–Schönefeld used SXF; the Berlin Brandenburg Airport has the airport code BER, which is also part of its branding. The airports of Hamburg (HAM) and Hannover (HAJ) are less than 100 nautical miles (190 km) apart and therefore share
1872-919: The end. Examples include: A lot of minor airfields without scheduled passenger traffic have ICAO codes but not IATA codes, since the four letter codes allow more number of codes, and IATA codes are mainly used for passenger services such as tickets, and ICAO codes by pilots. In the US, such airfields use FAA codes instead of ICAO. There are airports with scheduled service for which there are ICAO codes but not IATA codes, such as Nkhotakota Airport/Tangole Airport in Malawi or Chōfu Airport in Tokyo, Japan. There are also several minor airports in Russia (e.g., Omsukchan Airport ) which lack IATA codes and instead use internal Russian codes for booking. Flights to these airports cannot be booked through

Some airports, for example, cross several municipalities or regions, and therefore, use codes derived from some of their letters, resulting in: Other airports—particularly those serving cities with multiple airports—have codes derived from
1976-474: The following format: Most large airports in Canada have codes that begin with the letter "Y", although not all "Y" codes are Canadian (for example, YUM for Yuma, Arizona , and YNT for Yantai , China), and not all Canadian airports start with the letter "Y" (for example, ZBF for Bathurst, New Brunswick ). Many Canadian airports have a code that starts with W, X or Z, but none of these are major airports. When
2028-593: The form of " YYZ ", a song by the rock band Rush , which utilizes the Morse code signal as a musical motif. Some airports have started using their IATA codes as brand names , such as Calgary International Airport (YYC) and Vancouver International Airport (YVR). Numerous New Zealand airports use codes that contain the letter Z, to distinguish them from similar airport names in other countries. Examples include HLZ for Hamilton , ZQN for Queenstown , and WSZ for Westport . Predominantly, airport codes are named after
2080-585: The former People Express hub at Newark International Airport (EWR, now Newark Liberty International Airport ) in Newark , New Jersey . All flights at Britt's original and long-standing operation at the Chicago O'hare hub were also transitioned to flying as Continental Express however the entire Chicago operation was discontinued in early 1989. Britt also had a single route from the former Chicago Meigs Field airport to Springfield, IL which continued until 1991. According to

The code also sometimes comes from
2288-463: The notorious dip in the middle of the runway. In addition, 41 feet of length was added to the runway and retaining walls were built on the side. In 2010, crews widened the airfield's safety areas from 150 feet to 250 feet, installed an Engineered Materials Arrestor System (EMAS) and finished ancillary aspects of the projects. Work on the EMAS was scheduled at night to prevent disrupting operations. This system

This is not unusual since other mountain airports like Sun Valley have similar statistics. When flying to the Telluride Regional Airport, pilots must be aware of unique issues impacting the airfield including high terrain exceeding 14,000 feet (4,300 m), as well as
2444-501: The same first and middle letters, indicating that this rule might be followed only in Germany. Many cities retain historical names in their airport codes, even after having undergone an official name/spelling/transliteration change: Some airport codes are based on previous names associated with a present airport, often with a military heritage. These include: Some airports are named for an administrative division or nearby city, rather than

YUL is used for Montréal–Trudeau (UL was the ID code for the beacon in the city of Kirkland , now the location of Montréal–Trudeau). While these codes make it difficult for the public to associate them with a particular Canadian city, some codes have become popular in usage despite their cryptic nature, particularly at the largest airports. Toronto's code has entered pop culture in
2548-504: The two-letter code of the radio beacons that were the closest to the actual airport, such as YQX in Gander or YXS in Prince George . Four of the ten provincial capital airports in Canada have ended up with codes beginning with YY, including: Canada's largest airport is YYZ for Toronto Pearson (as YTZ was already allocated to Billy Bishop Toronto City Airport , the airport was given
2600-529: The use of two letters allowed only a few hundred combinations; a three-letter system of airport codes was implemented. This system allowed for 17,576 permutations, assuming all letters can be used in conjunction with each other. Since the U.S. Navy reserved "N" codes, and to prevent confusion with Federal Communications Commission broadcast call signs , which begin with "W" or "K", the airports of certain U.S. cities whose name begins with one of these letters had to adopt "irregular" airport codes: This practice
