King Abdulaziz Air Base

King Abdulaziz Air Base carries the IATA code DHA — the three letters printed on boarding passes and baggage tags — and the ICAO code OEDR, used in flight plans and by air traffic control. It serves Dhahran, Saudi Arabia.

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.
