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.
46-536: Key West International Airport ( IATA : EYW , ICAO : KEYW , FAA LID : EYW ) is an international airport located in the City of Key West in Monroe County, Florida , United States, 2 miles (3.2 km; 1.7 nmi) east of the main commercial center of Key West. The relatively short 5,076-foot-long (1,547 m) runway limits the maximum size of aircraft that can serve the airport, along with restricting
92-514: A destination outside of Florida since 1961. Delta Connection's service to Orlando was also upgraded to regional jets at the same time, though Orlando service was discontinued by 2008. Main line jet service returned to Key West in 2009 when AirTran Airways , Key West's first low-cost carrier, started flights to Orlando International Airport on Boeing 737-700s. Around the same time, Delta Air Lines upgraded some of their Atlanta flights to main line service on Boeing 737s. The airport's runway, which
138-567: 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
184-401: A new departures area, an upgraded security checkpoint, additional baggage areas, and new gates featuring seven jet bridges . The project is expected to be completed in early 2025. In the year ending December 31, 2021, the airport had 66,550 aircraft operations, averaging 182 per day: 55% general aviation , 34% airline, 10% air taxi , and <1% military. At the time, 59 aircraft were based at
230-733: Is 5,076 feet long and 100 feet wide (1,547 x 30 m) and has an asphalt surface. The length of the runway limits the size of aircraft that can serve the airport. Currently the largest aircraft that serve the airport are the Airbus A319 and the similarly sized Boeing 737-700 , both shortened variants of the popular narrow-body mainline aircraft. Additionally, flights departing from EYW often have weight restrictions. The airport has two terminals designed by Mark Mosko and Dwane Stark of URS; Mosko also worked on Baltimore–Washington International Airport . The older ground-level terminal building opened in 1957 and now serves arriving passengers. The terminal
276-509: 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
322-646: Is a civilian aircraft produced by Beechcraft . It is also known as the Beech 99 Airliner and the Commuter 99 . The 99 is a twin-engine, unpressurized, 15 to 17 passenger seat turboprop aircraft, derived from the earlier Beechcraft King Air and Queen Air . It uses the wings of the Queen Air, the engines and nacelles of the King Air, and sub-systems from both, with a specifically designed nose structure. Designed in
368-617: 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
414-523: 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
460-513: 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
506-543: 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

#1732802047767552-416: 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
598-571: 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
644-751: The 1960s as a replacement for the Beechcraft Model 18 , it first flew in July 1966. It received type certification on May 2, 1968, and 62 aircraft were delivered by the end of the year. In 1984, the Beechcraft 1900 , a pressurized 19-passenger airplane, was introduced as the follow-on aircraft. Production ended in early 1987 with 239 airframes completed. Nearly half the Beech 99s in airline service are now operated as freighters by Ameriflight . In July 2018, 106 Beechcraft B99 were in airline service, all in
690-592: The 1970s and 1980s primarily with nonstop flights to Miami but also with nonstop service to Fort Lauderdale, Naples, and Tampa. According to the Official Airline Guide (OAG), these air carriers included Air Florida Commuter , Dolphin Airlines, Gull Air, Jetstream International Airlines , Pro Air Services, Provincetown-Boston Airlines (and its successor Bar Harbor Airlines ), Southeast Airlines, and Southern Express. Turboprop aircraft operated into
736-903: The Southwest brand with Boeing 737-700 jetliners. Southwest Airlines ended service to Key West Airport in 2014. 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 ,
782-452: 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 . Beechcraft C99 The Beechcraft Model 99
828-481: 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
874-527: The airport before introducing regional jet service in the 2010s. By the early 1990s, both USAir and Eastern Air Lines ended jet service to Key West, and all commercial service to Key West would be operated by propeller aircraft for the rest of the decade. In 1993, Cape Air began service to Key West with flights to Naples using Cessna 402s . Service expanded in 1996 with flights to Fort Lauderdale and Fort Myers (the latter of which continued operating until 2013). Other airlines operating at Key West in
920-747: The airport did not have a paved runway until around 1956. National served Key West for nearly 25 years and later operated Convair 340 and Convair 440 prop aircraft, as well as Lockheed L-188 Electra turboprops, into the airport. In 1968, National began the first jet flights into Key West with Boeing 727-100s , providing nonstop service to Miami. By 1969, National was operating daily 727 jet service direct to Washington National Airport , Philadelphia International Airport , and John F. Kennedy International Airport via intermediate stops in Miami , West Palm Beach , and Orlando . Several other airlines also began operating jet service into Key West. In 1979, Air Florida
966-956: The airport included the British Aerospace BAe Jetstream 31 , Beechcraft 1900C , Beechcraft 1900D , Beechcraft C99 , CASA 212 Aviocar, Embraer EMB-110 Bandeirante , Embraer EMB-120 Brasilia , Nord 262 and Saab 340 . Piston engine twin prop aircraft flown by commuter air carriers serving Key West included the Douglas DC-3 , Martin 4-0-4 , and Piper Navajo . Delta Connection carrier Comair began service to Delta Air Lines ' hub in Orlando in 1988 and also briefly had service to Tampa and Fort Lauderdale as well. American Eagle Airlines began service from Key West to American Airlines ' hub in Miami in 1989. American Eagle operated Saab 340 and ATR-72 propjets into

#17328020477671012-440: 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,
1058-418: 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
1104-579: The airport. On July 15, 2017, Key West International Airport was awarded a grant of $ 6.5 million by the FAA to assist in a $ 10 million runway project. The project added 227 feet (69 m) to the runway for takeoffs and landings as well as added 10-foot (3.0 m)-wide shoulders paved on each side of the runway. Construction work began in January 2018 and all construction was done at night. Key West International Airport covers 334 acres (135 ha ) at an elevation of 3 feet (1 m). Its one runway , 09/27,
1150-659: The airport: 39 single-engine, 13 multi-engine, 3 jet, 3 helicopter and 1 ultralight. Allegiant, American Airlines, and Delta Air Lines operate mainline jets into Key West, primarily the Airbus A319 . JetBlue operates the Airbus A220 . United Airlines operates the Boeing 737-700 . American Eagle, Delta Connection, and United Express operate regional jets, including the CRJ700 and Embraer E-Jets . Silver Airways operates ATR 42 and ATR 72 turboprop aircraft. Key West's traffic
1196-448: The baggage claim area was then expanded into the former departure lounge. The two buildings are connected by an enclosed walkway. Parking for 300 vehicles is at ground level beneath the newer terminal—150 spaces for rental cars and 150 for the public. In November 2022, the airport broke ground on the construction of a new $ 98.8 million passenger concourse. This concourse will be nearly 50,000 square feet (4,600 m) in size and feature
1242-502: 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
1288-405: The early 1990s included Airways International (with flights to Fort Lauderdale and Miami), Pan Am Express (with flights to Miami), Paradise Island Airlines (operating code sharing service for Carnival Air Lines to Fort Lauderdale), and USAir Express (later known as US Airways Express with flights to Miami and Tampa). Gulfstream International Airlines also began service to Key West in
1334-530: The early 1990s with flights to Miami and Tampa. Gulfstream would later operate as Continental Connection , the regional brand of the now-defunct Continental Airlines . Gulfstream has since been rebranded as Silver Airways , who still serves Key West today. In 2002, Delta Connection carrier Atlantic Southeast Airlines began regional jet service to Delta's hub in Atlanta . This brought jet service back to Key West as well as Key West's first non-stop flight to
1380-934: 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
1426-557: The first three letters of the city in which it is located, for instance: The code may also be a combination of the letters in its name, such as: Sometimes the airport code reflects pronunciation, rather than spelling, namely: For many reasons, some airport codes do not fit the normal scheme described above. 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

1472-478: 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
1518-597: 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
1564-487: The international air booking systems or have international luggage transferred there, and thus, they are booked instead through the airline or a domestic booking system. Several heliports in Greenland have 3-letter codes used internally which might be IATA codes for airports in faraway countries. There are several airports with scheduled service that have not been assigned ICAO codes that do have IATA codes, especially in
1610-575: The main Naval Air Station for fixed-wing and lighter-than-air ( blimp ) aircraft on Boca Chica Key . After the war, the city took over what became Key West Municipal Airport. In January 1953, the city gave Monroe County the title to Meacham Field, allowing the county to apply for Federal Aviation Administration grants. Around the same time, the airport became Key West International Airport. National Airlines began flights to Miami in 1944 with Lockheed Lodestar twin prop aircraft, although
1656-612: 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
1702-416: 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
1748-506: 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
1794-500: The station code of Malton, Mississauga , where it is located). 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
1840-515: 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
1886-529: 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

1932-635: The weight of flights departing. Key West's aviation history began in 1913 with a flight to Cuba by Augustin Parla. In 1928, Pan American Airways began scheduled flights from Key West. The main runway at Meacham Field was pressed into U.S. Army use after the Pearl Harbor attack , as well as into U.S. Navy use later in World War II as an alternative to the Trumbo Point seaplane base and
1978-528: Was 4,801 feet (1,463 m) at the time, was the shortest runway to be regularly used by 737s in North America. AirTran later added flights to Tampa in 2011. By the end of 2012, Southwest Airlines took over AirTran's flights to Orlando and Tampa as part of the merger of the two airlines. Southwest also added service to New Orleans in March 2013. However, in 2014, Southwest discontinued all service to
2024-502: Was expanded with the addition of a second building elevated over the parking lot in February 2009. With an area of about 30,000 square feet (2,800 m), it more than doubled the airport's terminal space. The newer building includes an elevated roadway and houses ticketing, check-in, and the airport's security checkpoint. The older building was then renovated with the former ticketing area becoming an expanded departure gate lounge, and
2070-460: Was generally fairly stagnant to start the new millennium but gradually began increasing at the end of the 2000s with the addition of the new terminal and the introduction of low-cost jet service operated by AirTran , as well as mainline jet service by Delta . When Southwest acquired AirTran in 2011, it continued to operate flights from the airport, first under the AirTran brand and then under
2116-512: Was operating five nonstop flights a day to Miami with Boeing 737 jetliners. In 1987, Eastern Airlines was operating daily mainline Boeing 727-100 jet service nonstop to Miami. By 1989, Piedmont Airlines was operating six nonstop flights a day to Miami with Fokker F28 Fellowship twin jets. This F28 jet service was then continued by USAir following its acquisition of and merger with Piedmont. A number of commuter and regional airlines also served Key West with turboprop and prop aircraft during
