Siem Reap-Angkor International Airport

Siem Reap-Angkor International Airport carries the IATA code SAI — the three letters printed on boarding passes and baggage tags — and the ICAO code VDSA, used in flight plans and by air traffic control. It serves Siem Reap, Cambodia.

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.
