Siem Reap-Angkor International Airport — Siem Reap, Cambodia

Opened in October 2023, SAI represents Cambodia's newest major airport, built roughly 30 miles from Siem Reap city center to replace an older, smaller airport that sat too close to the Angkor Archaeological Park to allow further runway expansion. The new facility was designed specifically to accommodate long-haul wide-body aircraft, aiming to draw direct international flights from farther afield rather than relying so heavily on connections through Bangkok, Singapore, or other regional hubs. Siem Reap serves as the gateway to Angkor Wat and the surrounding temple complexes, among the largest religious monuments ever constructed and a UNESCO World Heritage site that anchors Cambodia's entire tourism economy. SAI's much larger capacity reflects Cambodian officials' ambitions to substantially increase annual visitor numbers to the Angkor temples in the years ahead. The longer drive into town from the new airport represents a tradeoff many travelers weigh against the previous facility's greater convenience.
