Phnom Penh is served by Phnom Penh International Airport (PNH), Cambodia's capital and busiest airport. It offers a wide range of regional connections from across Asia and key long-haul arrivals, with competitive fares driven by the presence of both full-service and low-cost carriers flying into PNH.
The most frequent and affordable flights to Phnom Penh are from major hubs and tourist destinations within Southeast Asia. Key arrival routes include from Bangkok (BKK/DMK), Singapore (SIN), Kuala Lumpur (KUL), Ho Chi Minh City (SGN), and Siem Reap (REP). For travel from East Asia, direct services from Guangzhou (CAN), Seoul (ICN), and Taipei (TPE) are common into PNH. Connections from Europe and Australia typically arrive via the major Asian hubs before a final leg to Phnom Penh.
The market for arrivals into Phnom Penh is highly competitive, featuring a mix of full-service airlines like Singapore Airlines, Korean Air, and Qatar Airways flying into PNH, and regional low-cost carriers such as AirAsia, Vietjet Air, and Jetstar Asia. Cambodia Angkor Air is the national carrier, operating key domestic and regional routes into the capital.
To secure cheap flights to Phnom Penh, book regional arrivals from within Southeast Asia 4-8 weeks in advance for the best deals. For flights from East Asia or long-haul origins into PNH, start monitoring prices 2-4 months ahead. Be flexible with dates and use fare comparison tools to check both full-service and low-cost options into Phnom Penh. A common strategy is to book a low-cost flight from a major hub like Bangkok or Singapore to PNH after first flying into that hub on a separate long-haul ticket — this can yield significant savings over a direct through-fare to Cambodia.
