If you’ve ever wondered why airport codes often seem like a random jumble of letters, you’re not alone. These three-letter codes, known as IATA (International Air Transport Association) codes, may look cryptic, but they hold fascinating stories about geography, history, and even quirks of aviation.
These codes are used by airlines, air traffic controllers, and passengers to identify airports quickly and efficiently. Most airport codes are issued by the International Air Transport Association (IATA) and serve as a standardized method for identifying airports globally.
Let’s decode some of the most interesting airport codes around the world.
Why airport codes matter
Beyond ticketing and logistics, IATA codes are vital for aviation safety and international communication. Pilots, air traffic controllers, and airlines worldwide use them to prevent confusion. Even when airport names or cities change, their codes often remain the same—serving as historical markers and practical tools.
The geographic codes
Many airport codes are straightforward references to the city or region they serve:
- JFK (New York’s John F. Kennedy International Airport): Named after the U.S. President in 1963, JFK retained the “J” from its original code, IDL, for Idlewild Airport.
- LAX (Los Angeles International Airport): The “X” was added to the two-letter Los Angeles identifier when aviation standards expanded to three letters in the 1930s.
- ORD (Chicago O’Hare International Airport): O’Hare’s code originates from Orchard Field, the airport’s original name before being renamed to honor World War II hero Edward O’Hare.
The historic codes
Some airport codes reflect a slice of history:
- YVR (Vancouver International Airport): The “Y” is a hallmark of Canadian airport codes, a leftover from the country’s early reliance on weather stations. “VR” stands for Vancouver.
- SYD (Sydney Kingsford Smith Airport): Named after aviation pioneer Charles Kingsford Smith, this airport has carried the same code since it was first established in 1920.
- ATL (Hartsfield-Jackson Atlanta International Airport): Known for being one of the busiest airports globally, ATL honors former Atlanta mayors William B. Hartsfield and Maynard Jackson.
The confusing codes
Some codes seem completely disconnected from their cities:
- EWR (Newark Liberty International Airport): Why not “NEW”? The “N” designation was already in use by the Navy, so Newark received a more unique code.
- MCO (Orlando International Airport): Once the site of McCoy Air Force Base, the airport retained the abbreviation after transitioning to civilian use.
- PIE (St. Pete–Clearwater International Airport): This Florida airport pays homage to its hometown of Pinellas County, not an abundance of baked goods!
The fun and quirky
Some codes bring a smile to travelers’ faces:
- LOL (Derby Field, Nevada): A tiny airport in Nevada with a humorous code that’s impossible to forget.
- OMG (Omega Airport, Namibia): This seldom-used airport in Africa has a code that makes every traveler exclaim!
- FUN (Funafuti International Airport, Tuvalu): This remote Pacific island embraces its code as part of its charm.
The legacy codes
Occasionally, a code reflects an old identity:
- BEY (Beirut-Rafic Hariri International Airport): A relic of the city’s French colonial past, “BEY” stems from “Beyrouth,” Beirut’s French name.
- LED (Pulkovo Airport, St. Petersburg, Russia): A nod to Leningrad, the city’s name during the Soviet era.
- SGN (Tan Son Nhat International Airport, Ho Chi Minh City, Vietnam): The code comes from the city’s former name, Saigon.
