Budapest Liszt Ferenc International Airport

Budapest Liszt Ferenc International Airport carries the IATA code BUD — the three letters printed on boarding passes and baggage tags — and the ICAO code LHBP, used in flight plans and by air traffic control. It serves Budapest, Hungary.

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.
