Owen Roberts International Airport

Owen Roberts International Airport carries the IATA code GCM — the three letters printed on boarding passes and baggage tags — and the ICAO code MWCR, used in flight plans and by air traffic control. It serves George Town, Cayman Islands.

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.
