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.
42-536: Reid–Hillview Airport of Santa Clara County ( IATA : RHV , ICAO : KRHV , FAA LID : RHV ) is in the eastern part of San Jose , in Santa Clara County , California , United States . It is owned by Santa Clara County and is near the Evergreen district of San Jose where aviation pioneer John J. Montgomery experimented with gliders in 1911. Reid–Hillview Airport was also the official general aviation airport for
84-761: A larger flow of these type of aircraft to land. In 2010, San Jose State University 's aviation program relocated to Reid–Hillview. The university operates out of the Swift Building, where it holds classes during the academic year. In 2018, the Board of Supervisors voted to study consolidating general aviation at San Martin Airport . On December 4, 2018, and again the following year, the board voted against accepting additional Federal Aviation Administration (FAA) funding that would have been contingent on Reid–Hillview's continued operation through 2051. Previously accepted grants require
126-550: 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
168-526: A study that found elevated blood lead levels in children living near the airport. On August 16, 2021, airport officials responded to the study by announcing that fixed base operators would switch to unleaded aviation fuel. After which Santa Clara County's supervisor, Cindy Chavez, testified at the United States House Oversight Subcommittee on Environment in opposition of the national use of leaded aviation fuel. The hearing resulted in
210-499: 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
252-411: Is also capacity-constrained and surrounded by urban development, including the low-income, minority Washington-Guadalupe and Alviso neighborhoods. For years, local activists have pushed to close the airport, supported by Santa Clara County Supervisors Blanca Alvarado and Cindy Chavez . Residents and officials have cited the airport's proximity to 21 schools and childcare centers as a concern due to
294-519: Is at the entrance to the airport at Cunningham Avenue. Enterprise car rental is available on the field next to the Airport Shoppe. The Santa Clara Valley Transportation Authority (VTA) has its Eastridge Transit Center across Tully Road at Eastridge Mall , about a half-mile walk southbound along Capitol Expressway. VTA runs bus rapid transit from the Diridon train station in downtown San Jose to
336-600: 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
378-518: 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
420-513: 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
462-532: 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

#1732872208844504-416: Is used for William P. Hobby Airport , the new Houston–Intercontinental became IAH. 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
546-548: The 2016 Super Bowl in Levi's Stadium (in nearby Santa Clara, CA). Reid–Hillview is a general aviation airport; there is no scheduled airline service. As with most general aviation airports air charter operations are available. The airport has a control tower that operates from 07:00 to 22:00 local time. The FAA classifies Reid–Hillview as a reliever airport for San Jose International Airport (SJC). Groundbreaking for Reid–Hillview airport came in 1937. Bob and Cecil Reid built
588-561: 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
630-560: The Eastridge Transit Center . Construction has also started on a light rail extension from the Alum Rock station to Eastridge. As of 2016, Reid–Hillview Airport had vending machines, a pilot's lounge and break room. Santa Clara County passed a new law stating the terminal would no longer allow unhealthy food or drinks to be sold inside. This meant that coffee and all the vending machines that used to be there would no longer exist in
672-567: The Watsonville Municipal Airport following the 1989 Loma Prieta earthquake , after mountain and coastal roads were blocked, cutting off Santa Cruz and Watsonville from relief efforts by ground. The Watsonville Airport estimates that it received 100 short tons (91 t) of supplies via the airlift during the week following the quake. John McAvoy and Bill Dunn of the Reid–Hillview Airport Association received
714-515: The 1990 Grand Award from the Bay Area's Metropolitan Transportation Commission for organizing the airlift. The airport continues to be used in emergency operations, including during the SCU Lightning Complex fires in 2020. Santa Clara County published an over 120-page master plan proposing improvements and expansions at Reid–Hillview. In the mid-2000s, the county announced they would demolish
756-569: The Garden City Airport in 1935, which was quickly closed to make room for U.S. Route 101 . Their second site was northwest of the Hillview golf course, hence the name. Until 1946, the single runway was unpaved. Reid–Hillview was a single runway airport until 1965, when a second runway was added. The control tower opened in October 1967. The airport was the origin for an emergency supply airlift to
798-502: 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 . United States House Oversight Subcommittee on Environment The Subcommittee on Environment
840-481: 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
882-440: The airport itself instead of the city it serves, while another code is reserved which refers to the city itself which can be used to search for flights to any of its airports. 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,

#1732872208844924-418: The airport's former name, such as Orlando International Airport 's MCO (for Mc C o y Air Force Base), or Chicago's O'Hare International Airport , which is coded ORD for its original name: Or char d Field. 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
966-415: The airport's use of 100LL avgas , which contains lead. Activists consider the airport's continued operation to be an example of environmental racism in the United States , arguing that 97% of the adjacent East San Jose neighborhood at risk of lead poisoning identifies as predominantly non white, predominantly low-income Latino and Vietnamese-American residents. This study also brought about conversations of
1008-491: The code SHA, while the newer Shanghai–Pudong adopted PVG. 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
1050-585: The committee committing to declaring leaded aviation fuel a health hazard by 2023. On August 18, the Board of Supervisors voted unanimously to close the airport as soon as the FAA approves of its closure, which would be no sooner than January 1, 2022, and mandate the use of unleaded fuel as soon as possible. The board also voted against funding an expansion of San Martin Airport, raising concerns that general aviation traffic would be diverted to San Jose International Airport , which
1092-747: The county and released in August 2021 found elevated blood lead levels in children living within a 1.5 miles radius of the airport. The study found that children in the affected region experienced blood lead levels of 0.83 micrograms per deciliter. This is nearly double the blood lead levels of children during the Flint water crisis , which were around 0.45 micrograms per deciliter. Nationally, over 360,000 children live in neighborhoods surround airports which use leaded aviation fuel. At Reid–Hillview, fixed-base operators (FBOs) compete for fuel sales, aircraft rentals and/or flight training. Capitol Expressway (County Route G21)
1134-413: The county to keep the airport open through 2031. In November 2020, it voted to begin the process of closing the airport in 2031 and redeveloping the land. Between 2019 and 2020, Santa Clara County undertook a community process to explore possible future uses for the airport site, resulting in a draft Reid–Hillview Vision Plan with the following vision statement: In August 2021, Santa Clara County released
1176-919: 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
1260-474: 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
1302-593: 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

There are several airports with scheduled service that have not been assigned ICAO codes that do have IATA codes, especially in
1386-612: The name of the airport itself, for instance: This is also true with some cities with a single airport (even if there is more than one airport in the metropolitan area of said city), such as BDL for Hartford, Connecticut 's B ra dl ey International Airport or Baltimore's BWI, for B altimore/ W ashington I nternational Airport ; however, the latter also serves Washington, D.C. , alongside Dulles International Airport (IAD, for I nternational A irport D ulles) and Ronald Reagan Washington National Airport (DCA, for D istrict of C olumbia A irport). The code also sometimes comes from
1428-479: The national use of leaded aviation fuel in piston engined aircraft, which contributes to 70% of airborne lead. A 2021 study by Dr. Sammy Zahran found unsafe levels of lead in the air above the southeastern side of the airport, exceeding the acceptable limit set by the National Ambient Air Quality Standards ; in response, that side of the airport was closed to visitors. A study commissioned by
1470-416: The one they are located in: Other airport codes are of obscure origin, and each has its own peculiarities: In Asia, codes that do not correspond with their city's names include Niigata 's KIJ , Nanchang 's KHN and Pyongyang 's FNJ . EuroAirport Basel Mulhouse Freiburg , which serves three countries, has three airport codes: BSL, MLH, EAP. Some cities have a name in their respective language which
1512-501: 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

They failed to follow up on this plan, and the second story has been sitting idle ever since. In the document, the county also planned on adding small expansions to the runway to allow turboprops and small business jets to land. Although turboprops and small business jets still land in the current runway, this minor expansion will allow

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

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 ,
1680-504: 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
1722-529: 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
