Banja Luka International Airport

Banja Luka International Airport carries the IATA code BNX — the three letters printed on boarding passes and baggage tags — and the ICAO code LQBK, used in flight plans and by air traffic control. It serves Mahovljani, Bosnia and Herzegovina.

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.
