Muan International Airport

Muan International Airport carries the IATA code MWX — the three letters printed on boarding passes and baggage tags — and the ICAO code RKJB, used in flight plans and by air traffic control. It serves Muan (Piseo-ri), South Korea.

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.
