Siem Reap is served by Siem Reap–Angkor International Airport (SAI), the new gateway to the iconic Angkor Wat temple complex. As Cambodia's premier tourist destination, it offers a focused network of direct arrivals primarily from major hubs and key cities across Asia, with strong seasonal variations in price and availability into SAI.
The most frequent and affordable flights to Siem Reap are from regional aviation and tourism hubs. Top arrival routes include from Bangkok (BKK/DMK), Singapore (SIN), Kuala Lumpur (KUL), Hanoi (HAN), and Ho Chi Minh City (SGN) into SAI. Direct arrivals from East Asian cities like Seoul (ICN), Taipei (TPE), and Guangzhou (CAN) are also common into Siem Reap. The domestic connection from Phnom Penh (PNH) to SAI is essential and operates frequently.
The market for arrivals into Siem Reap is served by a combination of full-service and low-cost carriers. Airlines like Thai Airways, Singapore Airlines, and Korean Air operate into SAI alongside low-cost leaders such as AirAsia, Jetstar Asia, and Vietjet Air. Cambodia Angkor Air provides key domestic and regional service into Siem Reap. This mix creates competition, particularly on popular tourist arrival corridors.
To find cheap flights to Siem Reap, book arrivals during the shoulder seasons (May-June, September-October) outside peak tourist periods into SAI. Secure regional arrivals 6-10 weeks in advance for the best prices into Siem Reap. For the domestic route from Phnom Penh (PNH) to SAI, booking 2-4 weeks ahead is usually sufficient. Always compare arrival fares into nearby hubs like Bangkok; it can sometimes be cheaper to fly into Bangkok on a competitive long-haul route and take a separate short-haul flight from there to Siem Reap.
