Airports in Cambodia
Cambodia has three international airports that receive flights from regional hubs:
- Phnom Penh International Airport (PNH) — The capital's main airport and Cambodia's busiest. Most international connections arrive here. Located about 10 km from the city center.
- Siem Reap Angkor International Airport (SAI) — Opened in 2023, this modern airport serves visitors to Angkor Wat and the temples of Angkor. It receives flights from regional Asian cities.
- Sihanoukville International Airport (KOS) — Serves the coastal resort city, primarily with flights from China and regional destinations.
Most US-originating itineraries route through Phnom Penh, though connecting to Siem Reap via a regional hub is also common.
Best Connection Hubs
Seoul Incheon (ICN)
Korean Air and Asiana Airlines offer excellent connections through Seoul. The flight from the West Coast to Seoul is approximately 12–13 hours, followed by a 5.5–6 hour flight to Phnom Penh. Incheon is consistently rated one of the world's best airports for layovers, with free transit tours, lounges, and amenities.
Tokyo Narita (NRT) / Haneda (HND)
Japan Airlines and ANA connect through Tokyo. The West Coast to Tokyo leg takes about 11–12 hours, with a 6–7 hour onward flight to Phnom Penh. Haneda is more centrally located if you want to explore Tokyo during a longer layover.
Hong Kong (HKG)
Cathay Pacific offers connections through Hong Kong. The transpacific leg takes 14–16 hours from the West Coast, with a short 2.5–3 hour flight to Phnom Penh or Siem Reap. This connection is popular because the final leg is very short.
Doha (DOH)
Qatar Airways flies from multiple US cities to Doha, then connects to Phnom Penh. This routing works well from the East Coast and Midwest, though the total journey time is typically 22–28 hours due to the westbound routing through the Middle East.
Bangkok (BKK)
While no nonstop US-Bangkok flights exist, Bangkok is a major regional hub with frequent short flights to both Phnom Penh (1 hour) and Siem Reap (1 hour). If you are already transiting through Asia, routing via Bangkok adds minimal time and offers many daily departures.
Tips for Booking Flights to Cambodia
- Book through a single alliance — Star Alliance (via Tokyo or Bangkok) and Oneworld (via Hong Kong or Doha) offer the most seamless connections with coordinated baggage handling
- Allow adequate layover time — Minimum 2–3 hours for international connections at major Asian hubs
- Consider a stopover — Many airlines allow free or low-cost stopovers at their hub city, letting you explore Seoul, Tokyo, or Hong Kong for a day or two
- Check visa requirements — US citizens can get a visa on arrival in Cambodia ($30 for a tourist visa) or apply for an e-visa in advance
- Fly during shoulder season — November–February is peak season; flying in March–May or September–October often yields lower fares
- Compare East vs. West routing — From East Coast cities, compare the Middle East routing (via Doha or Dubai) against the Pacific routing (via Seoul or Tokyo) for the best combination of price and travel time
Jet Lag Considerations
Cambodia is in the Indochina Time Zone (ICT), which is 12 hours ahead of Eastern Time and 15 hours ahead of Pacific Time. The significant time difference means jet lag will be a factor regardless of your routing. Most travelers need 3–5 days to fully adjust. Flying westbound via the Middle East or eastbound via the Pacific both result in similar jet lag challenges.
Bottom Line
Expect 18–22 hours of total travel time from the West Coast and 22–28 hours from the East Coast. Seoul, Tokyo, and Hong Kong offer the most efficient connections. No nonstop flights exist, so all itineraries require at least one stop, and many involve two connections.
