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.

The airport, located just off Bryan Boulevard , sits on
94-613: A Fixed-Base Operator that made sure the torches were lit at dusk, Maynard Field was named to honor a young North Carolinian pilot named Lt. Belvin Maynard. By 1922 it had competition to the west with Miller Field in Winston-Salem, and Charles Field, a single airstrip that was used mainly for barnstorming , and for take-off drills and landings for the Charles family. Piedmont Triad International Airport had its start in 1927 when
141-680: A 3,770 acre (1,526 ha) campus and has three runways. It is the third busiest airport in North Carolina, averaging 280 takeoffs and landings each day. PTI is owned and operated by the Piedmont Triad Airport Authority. This airport is included in the National Plan of Integrated Airport Systems for 2011–2015, which categorized it as a primary commercial service airport since it has over 10,000 passenger boardings (enplanements) per year. A proposal to rename
188-553: A 550 square foot cab for controllers. The base will be 15,650 square feet, and will house the new TRACON facility. Boom Supersonic has also built a 65-acre Superfactory , where they plan to manufacture their supersonic flagship airplane, the Overture, which will begin commercial operations in 2030, with groundbreaking starting in late 2022 and construction completing in June 2024. The site will create 1,750 jobs, and 200 internships for
235-634: A brief closure during the Great Depression, the airport reopened on May 17, 1937, with two all-weather runways. In time, Pitcairn Aviation built a hangar; Greensboro built a passenger station; the United States government established a weather bureau; and the Department of Commerce set up a radio tower. Passenger service was inaugurated by Dixie Flying Service on November 6, 1930, with a route to Washington, D.C. Pitcairn Aviation took over
282-493: 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
329-598: A maintenance base on the south side of the airfield. The following fixed-base operators are based at the Piedmont Triad International Airport: A significant investment is being made into the interstate highway network adjacent to the airport, which will result in easy access from industrial sites around the airport on interstate highways leading north, south, east and west. Major highways such as I-40, I-85 and I-74 are already in place, with connectors under construction and coming on line in
376-567: 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
423-675: A new terminal. Piedmont Airlines announced its intention to consolidate its operations at Greensboro, but in the months that followed, opened a hub in Charlotte instead. The new terminal complex was completed in 1982, designed by Reynolds, Smith & Hills and AHM Architects. The following year, the Marriott opened a $ 16 million, 300-room hotel on the airport property. The facility was renamed Piedmont Triad International Airport in 1987. TIMCO Aviation Services (now Haeco Americas) opened its world headquarters at PTI in 1990, and grew into one of
470-509: 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
517-523: 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

#1732780370929564-513: 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
611-543: 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
658-416: 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.

Sid Malloy, the pilot of the aircraft, landed with two bags of mail and took three bags of mail to be sent to Atlanta. After
752-571: 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
799-481: 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 the use of two letters allowed only
846-645: The 1970s the airport was renamed Greensboro–High Point Airport and then later Greensboro–High Point–Winston-Salem Regional Airport. Work on a new facility began in 1978 and the airport gained a greater prominence on the East Coast, offering passenger service from Delta Air Lines , Piedmont Airlines , United Airlines and Eastern Air Lines . Cargo carriers, including the postal service, textile manufacturers, and Federal Express–a new overnight letter and package delivery service–were shipping tons of freight each year. By 1975, airport officials began to plan for
893-523: 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 , is available. However, many railway administrations have their own list of codes for their stations, such as
940-551: The Tri-City Airport Commission selected 112 acres (45 ha) near the community of Friendship for an airport, and petitioned to become a stop along the congressionally authorized airmail route from New York to New Orleans. Racing pilot Captain Roscoe Turner referred to the current location of Piedmont Triad International Airport as "the best landing field in the south". Friendship, near Greensboro ,
987-482: 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 .

SECTION 20
#17327803709291034-481: 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

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,
1175-650: The airport to "Central North Carolina International Airport" passed in December 2017; the renaming was slated to become effective on January 1, 2018.

1316-502: 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
1363-934: 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

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
1457-478: 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
