IATA Codes (three-letter airport codes)
A vast majority of airports worldwide are assigned IATA Codes by the International Air Transport Association (IATA). Used as location identifiers, IATA Codes make the identification of airlines, destinations, and traffic documents simple and clear.
ICAO Codes (four-letter airport codes)
ICAO Codes play a bigger role in flight planning, airline timetables, reservations, baggage handling, and more. Proposed by the International Civil Aviation Organization (ICAO), ICAO Codes are attributed to all the airports around the world.
