Cambodia has three international airports that matter to most visitors: Siem Reap-Angkor, Techo International near Phnom Penh and Sihanouk International. This guide explains the airports we could confirm, the domestic routes reported in 2026, and planning tips. Most details come from news reports and an airports directory, so check timetables with the airline for your dates before you pay. We did not find official route lists from North America or Europe, so we do not list specific long-haul routes.
Main Airports
- Siem Reap-Angkor International (SAI): The gateway for Angkor, listed as an international airport.
- Techo International (KTI): The new airport for Phnom Penh, in Kandal province about 20 km from the city. It opened on 9 September 2025, according to a MarketBeat report, with an initial capacity of 13 million passengers, rising to 30 million after 2030 and 50 million by 2050.
- Sihanouk International (KOS): Serves Sihanoukville and the southern coast.
- Dara Sakor (DSY): A domestic airport in Koh Kong province. Air Cambodia has announced a Phnom Penh to Dara Sakor service.
The old Phnom Penh International Airport (PNH) was listed as closed on one directory, but the MarketBeat report says it stays open for military use, with its runway available for emergencies. Treat Techo as the airport for commercial flights and confirm your airport with your airline.
Airlines and Domestic Routes
According to a report citing Khmer Times and AeroRoutes, Cambodia Airways launched two domestic routes on 26 June 2026 with ATR 72-600 aircraft: Phnom Penh to Siem Reap with two daily rotations, and Siem Reap to Sihanoukville with one daily rotation. The same report says Air Cambodia already operates daily Phnom Penh to Siem Reap flights, and that AirAsia Cambodia has reportedly operated daily domestic services, with no route details. New schedules can change after launch, so check flight times, operating days and baggage rules with the airline.
International Flights
The MarketBeat report mentions Techo’s inaugural Air Cambodia flight from China and a later arrival from Singapore. Our sources do not give specific routes from North America or Europe, so use a flight search tool for your departure city and compare connections. Check the advice for any transit country, because the UK Foreign Office says escalation in the Middle East is causing airspace closures and flight delays or cancellations that can affect trips even if Cambodia is not your destination.
Flights and the Thailand Border
The UK says land crossings between Cambodia and Thailand remain suspended. If your trip includes both countries, book flights rather than an overland route, and confirm each leg before you pay.
Entry Steps Before You Fly
- Check whether you need a visa and apply for an e-visa or plan to buy one on arrival. See the Cambodia visa guide.
- Submit the free e-Arrival Card within seven days before arrival if you land at Phnom Penh, Siem Reap or Sihanoukville, according to the UK government.
- Check your passport validity. The UK says it must be valid for at least six months from arrival.
- Have an onward or return ticket, according to Wikipedia.
Checklist Before You Book
- Compare more than one search tool and check the total with bags and taxes.

- Confirm which airport serves Phnom Penh on your booking.
