Airport codes explained
An airport code is a short identifier for an airport. The IATA code has three letters, like JFK, and is printed on tickets, boarding passes and bag tags. The ICAO code has four letters, like KJFK, and is used by pilots and air traffic control. Airlines have both kinds too: two characters from IATA, three letters from ICAO.
