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.
48-568: John Glenn Columbus International Airport ( IATA : CMH , ICAO : KCMH , FAA LID : CMH ) is an international airport located 6 miles (9.7 km; 5.2 nmi) east of downtown Columbus, Ohio . Formerly known as Port Columbus International Airport , it is managed by the Columbus Regional Airport Authority , which also oversees operations at Rickenbacker International Airport and Bolton Field . The airport code "CMH" stands for "Columbus Municipal Hangar,"
96-463: A $ 92 million parking garage including an underground terminal entrance, new rental car facilities, dedicated ground transportation area, improved eight-lane terminal access on two levels, and a new atrium and entrances in 2000, which were designed by URS Corporation . On April 25, 2004, a new 195-foot (59 m) control tower directed its first aircraft. This began several major facility enhancements to be constructed through 2025. On October 21, 2010,
144-493: 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
192-567: 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
240-401: A new arrivals/departures board replaced the old one in the main entrance area. Columbus began its Terminal Modernization Program in late 2012, which included new terrazzo flooring throughout the airport, new ceilings, new restrooms, more TSA security lanes, and new LED lighting. Construction started on Concourse A in late 2012 and was completed throughout the terminal in early 2016. In 2013,
288-509: 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
336-469: Is accessible directly by taking exit number nine on Interstate 670 to International Gateway. Alternatively, drivers can also get to the airport from the east via Hamilton Road, just south of Interstate 270 , and enter at Sawyer Road or from the west via Stelzer Road. Connected to the terminal is a six-story parking garage that provides long-term and short-term parking. Lower cost satellite parking options, with continuous free shuttle service, can be found in
384-586: 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
432-513: 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
480-543: 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
528-416: 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

#1732791660808576-534: The COVID-19 pandemic . John Glenn Columbus International Airport has one terminal with three concourses, and a total of 29 usable gates. Non-precleared international flights arrive through Concourse C and are processed in the airport's customs facility. The airport has two fixed-base operators , which offer fuel (both avgas and jet fuel ), aircraft parking, conference rooms , crew lounges, snooze rooms, showers , courtesy transportation, and more. The airport
624-571: 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
672-814: The F-100 Super Sabre , RA-5 Vigilante , T-2 Buckeye , T-28 Trojan , OV-10 Bronco and T-39 Sabreliner . The diagram on the February 1951 Coast & Geodetic Survey instrument-approach chart shows runways 006/186 3550 ft long, 052/232 4400 ft, 096/276 4500 ft, and 127/307 5030 ft. A new $ 12 million terminal building opened on September 21, 1958. Jet airline flights (American 707s) started in April 1964. The April 1957 Official Airline Guide shows 72 airline departures each weekday: 41 TWA , 16 American , 6 Eastern , 6 Lake Central and 3 Piedmont . The first major airline to fly into Columbus
720-481: 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
768-457: The Blue, Red and Green parking lots along International Gateway. The Blue lot is the closest to the terminal and also offers some covered parking. The cost of parking a car in the blue lot is $ 9 per 24 hours. The Red Lot costs $ 7 per 24 hours and the green lost costs $ 5 per 24 hours to park. The Green lot is the furthest away from the terminal. Additionally, there is a free cell phone lot accessed from
816-543: The Columbus area. A number of taxi services provide outbound transportation in the taxi lane. In 2001, Executive Jet Aviation (now known as NetJets ), opened up a 200,000-square-foot (19,000 m) operational headquarters. In November 2006, Skybus Airlines began leasing 100,000 square feet (9,300 m) of office and hangar facilities at the Columbus International AirCenter adjacent to
864-523: 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
912-475: 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 . Skybus Airlines Too Many Requests If you report this error to
960-481: 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
1008-421: The airport completed a $ 140 million runway improvement that moved the south runway farther from the north runway. This created a buffer distance that enables simultaneous takeoffs and landings on the north and south runways, increasing air traffic volume. Columbus mayor Michael B. Coleman commented, "As the city grows, the airport needs to grow with it." In 2019, construction began on a new car rental facility at
SECTION 20
#17327916608081056-473: The airport in May 2023. Sun Country Airlines announced a plan to fly to the airport during the 2023 summer season. Plans have been in development for many years for a new terminal, set to begin construction in 2025 to replace the current, aging building, beginning with the new car rental facility completed in 2021. In spring 2023, the airport prepared for a record travel summer matching traffic levels from before
1104-794: The airport is not used to receiving on a regular basis, such as the Boeing 767 and 777, are chartered through John Glenn and serviced by Lane Aviation. Due to the COVID-19 pandemic , many new, current, and to-be-expanded routes were canceled or reduced. Air Canada temporarily suspended service to Columbus, while airlines such as United, American, and Delta used smaller aircraft for some of their mainline routes. Many of these routes saw an increase of service in mid-2021 as restrictions lifted and demand for air travel grew. Startup Breeze Airways also selected Columbus as one of its launch destinations in July 2021 with five routes. The airline added additional routes from
1152-440: 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,
1200-418: 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
1248-455: The airport, with an estimated budget of $ 140 million. This facility moves car rental out of the parking garage, opening up more spaces for travelers. The new building opened in late 2021, and utilizes electric buses to transport passengers. Many airlines introduced new routes in the late 2010s, with the addition of Spirit Airlines with multiple destinations and Alaska Airlines with one daily flight to Seattle. Occasionally, larger aircraft that
1296-439: The airport. Regional carrier Republic Airways operates a large crew and maintenance base at the airport. The airport has its own police and fire departments (ARFF-C). For the 12-month period ending December 31, 2021, the airport had 98,185 aircraft movements, an average of 269 per day. This was 65% commercial , 19% general aviation , 16% air taxi , and <1% military . For the same time period, 88 aircraft were based at

The codes are published semi-annually in
1392-502: 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
1440-669: The eastern air terminus of the Transcontinental Air Transport air-rail New York to Los Angeles transcontinental route. Passengers traveled overnight on the Pennsylvania Railroad 's Airway Limited from New York to Columbus; by air from Columbus to Waynoka , Oklahoma; by rail again on the Atchison, Topeka & Santa Fe from Waynoka to Clovis , New Mexico; and by air from Clovis to Los Angeles. The original terminal building and hangars remain;
1488-934: 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

1536-557: 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
1584-478: 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
1632-597: 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
1680-509: The hangars are still in use, but the old terminal sits derelict. During World War II, most of the facility was taken over by the U.S. Navy , which established Naval Air Station Columbus in 1942. NAS Columbus was closed and the facility relinquished back to civilian authorities in 1946. Also, during the war, the government established a government-owned aviation factory on the grounds of the airport known as Air Force Factory 85 , eventually operated by North American Aviation . The plant produced
1728-525: The hub in 2003 due to financial losses and the post-9/11-decline in air travel. The airport was the home base of short-lived Skybus Airlines , which began operations from Columbus on May 22, 2007. The airline touted themselves as the cheapest airline in the United States , offering a minimum of ten seats for $ 10 each on every flight. Skybus ceased operations April 4, 2008. A $ 70 million renovation of airport facilities, designed by Brubaker/Brandt ,

There are several airports with scheduled service that have not been assigned ICAO codes that do have IATA codes, especially in
1824-612: 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
1872-416: 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
1920-480: The original name of the airport. John Glenn Columbus International Airport is primarily a passenger airport. It provides 148 non-stop flights to 31 airports via nine airlines daily. On May 25, 2016, the Ohio General Assembly passed a bill to rename the airport from Port Columbus International Airport to its current name, in honor of astronaut and four-term U.S. senator John Glenn . The name change
1968-608: The outbound side of International Gateway. The Columbus Metropolitan Area's bus service, the Central Ohio Transit Authority (COTA), has a bus service between the airport and downtown Columbus. COTA's 7 Mt. Vernon route is operated from downtown, with every other bus serving either the airport or Easton Transit Center. The GoBus Rural Inter-City Bus Service operates a thrice daily schedule to Athens , via Lancaster , Logan , and Nelsonville . Inbound taxi services operate through numerous taxi businesses in

2016-506: 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
2064-500: 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
2112-515: 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
2160-417: Was TWA , and it kept a presence at Columbus over 70 years during the era of airline regulation. TWA offered a club for exclusive passengers up until 2000 when America West took over a gate held by TWA and the club itself due to financial problems. The site of the club is now Eddie George ‘s 27 grille. Columbus was formerly a hub of America West Airlines , which it opened in 1993, but the company closed
2208-435: Was completed in 1996, which is now Concourse C, and was expanded in 2002. Between 1998 and 2000, numerous airport expansion and renovation projects were completed, including a $ 25 million terminal renovation in 1998 that included additional retail shops, new flight information displays, enhanced lighting, upgraded flooring, and a new food court. Also, new hangars and office spaces were completed for NetJets in 1999, as well as
2256-572: Was initiated in 1979 for the airport's 50th anniversary and completed in 1981. This upgraded the airport's capacity to 250 flights per day by adding what is known today as Concourse B and added fully enclosed jetways at every gate. Ten years later in 1989, a second, $ 15.5 million, seven-gate south concourse (now Concourse A) was dedicated. The concourse was used exclusively by US Airways at the time, and later housed hubs for both America West Airlines until 2003, and Skybus Airlines until they shut it down in 2008 due to their bankruptcy. A north concourse
2304-512: Was unanimously approved by the airport's nine-member board on May 24, 2016. Ohio Governor John Kasich signed the bill into law on June 14, 2016, with the name change becoming official 90 days later.
