John A. Osborne Airport

John A. Osborne Airport carries the IATA code MNI — the three letters printed on boarding passes and baggage tags — and the ICAO code TRPG, used in flight plans and by air traffic control. It serves Gerald's Park, Montserrat.

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.
