London Gatwick Airport

London Gatwick Airport carries the IATA code LGW — the three letters printed on boarding passes and baggage tags — and the ICAO code EGKK, used in flight plans and by air traffic control. It serves London, United Kingdom.

IATA codes are assigned by the International Air Transport Association for passenger-facing use; the four-letter ICAO code encodes region and country and belongs to the operational side of aviation.
