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.
56-521: Westchester County Airport ( IATA : HPN , ICAO : KHPN , FAA LID : HPN ) is a county-owned airport in Westchester County , New York , United States, three miles (6 km) northeast of downtown White Plains , with territory in the towns of North Castle and Harrison, New York , and the village of Rye Brook, New York . It is sometimes referred to as the White Plains Airport and
112-404: A primary commercial service airport. Per Federal Aviation Administration records, the airport had 872,023 passenger enplanements in calendar year 2019. Westchester County Airport was built during World War II in 1942 as a home to an Air National Guard unit to protect New York City and Rye Lake, part of the city's water supply system . In May 1983, with the growth of suburban Westchester,
168-550: 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
224-499: 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
280-544: Is also the home of the New York Wing Civil Air Patrol headquarters, the Lt. Anthony L. Willsea Cadet Squadron (NY-422). Aircraft Rescue Fire Fighting (ARFF) is provided by Airport Operations Crews. The airport owns three ARFF apparatuses (three Oshkosh Striker 1500s), two of which are in service full-time. The ARFF Crews only respond to aircraft emergencies. All structure-related fire and rescue calls are deferred 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
392-518: 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
448-650: 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 ,
504-513: 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
560-646: Is its Voluntary Restraint from Flying Program (VRFF), sometimes referred to as a voluntary curfew, that helps assuage anti-airport complainants by requesting—not mandating—that operators refrain from flying into the airport between midnight and 6:30 AM. Those that breach the VRFF are reminded of the initiative and notified of any noise complaints that may have resulted from their operations. The airport's Airport Noise and Operations Monitoring System (ANOMS) collects noise data from remote noise-monitoring terminals, and both registered aircraft and community noise levels are published in
616-532: 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

The study noted that HPN was one of only three airports in the state that increased its enplanements, surpassing the U.S. benchmark. It also noted that the cumulative economic activity for
952-661: The Airport Monitor. This system works in conjunction with the High Range Noise Event (HRNE) Program; ANOMS staff can identity any operator who causes a maximum noise level event of 90.0 decibels or higher at any of its remote noise monitor terminals and advise them in order to prevent future noise level transgressions. As of September 2020, there are no fines, penalties, or aircraft restrictions associated with this program. Additionally, HPN prohibits intersection takeoffs from its runways and restricts maintenance run-ups &
1008-616: The Guard unit abandoned Westchester Air National Guard Base and moved to Stewart International Airport , in Orange County . The first scheduled airline flights were by American Airlines in late 1949 with a weekday morning flight from New York LaGuardia Airport to HPN continuing to Syracuse Hancock International Airport and beyond and returning in the evening. Mohawk Airlines replaced American in 1955; Mohawk and successor Allegheny Airlines served HPN until 1979. The first scheduled jet flight
1064-541: 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 . Altair Airlines Altair Airlines was an airline based in Philadelphia . It
1120-481: 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
1176-553: The airport began a $ 30 million construction project to expand the terminal and ramp areas. The project will expand the terminal by 20% and include additional check-in, screening and passenger waiting areas. The expansion will also include the addition of four new jet bridges . A separate terminal with "lodge-like ambiance" to serve passengers of private jets opened in 2019. In its effort to mitigate aircraft noise pollution in neighboring communities, HPN maintains six major noise abatement programs that are in effect daily. One of them

An aircraft must have a maximum gross weight of 120,000 pounds or less, or permission from the manager, to land at the airport. Westchester County Airport has one small, three-level terminal with six gates, of which only four can be used simultaneously because only four aircraft can be scheduled to use
1288-882: The airport include American Airlines , Northwest Airlines , Republic Airlines (1979-1986) , United Airlines and USAir (now part of American Airlines ). New start up carriers Air Florida , AirTran Airways , Carnival Air Lines , Midway Airlines and New York Air also served the airport.

Examples include: Sometimes,
1400-456: The airport was approximately $ 736 million. On April 27, 2020, the airport was closed to general aviation traffic for one week and commercial airlines for about a month so Runway 16/34 could be repaved, a project originally scheduled to span four months with construction only occurring from midnight to 6 AM. This decision was made in the midst of COVID-19 pandemic-related air travel cuts , which drastically reduced commercial airline service to

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
