Wellington International Airport

Wellington International Airport carries the IATA code WLG — the three letters printed on boarding passes and baggage tags — and the ICAO code NZWN, used in flight plans and by air traffic control. It serves Wellington, New Zealand.

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.
