Which Cambodia airport should you fly into and out of?

The best airport for your Cambodia trip is the one that fits your first stop and final night. Before choosing the cheapest fare, compare the whole journey: connections, baggage, transfers and any return trip to your arrival city.

Airport codes to know before booking

Techo took over operations from the former Phnom Penh airport in September 2025. For Siem Reap, search SAI rather than the old REP code. Older names may remain in guides or search results: check the code on your ticket and transfer booking.

If Angkor is the focus of your trip

Start by comparing flights into SAI. You can begin in Siem Reap without immediately adding a journey from Phnom Penh. Consider landing time, though: a late arrival is not a sightseeing day.

For a few nights entirely in Siem Reap, a return ticket through SAI may be simplest. If you continue to Phnom Penh, also compare flying home from KTI. Our Siem Reap arrival guide covers the onward transfer.

If you are visiting both Siem Reap and Phnom Penh

Search for a multi-city ticket: arrive in one city and depart from the other. Either direction can work. Choose according to available flights, total cost and how you want to begin and end the trip.

Compare two complete scenarios:

A multi-city ticket is not always cheaper. It can still avoid spending part of your final days retracing your route. Compare flight times as well: a cheaper ticket may require an extra transit night or transfer.

If you finish on the islands or in Kampot

Do not choose KOS simply because it looks close to the coast. Check that a useful flight operates on your date, reaches your next destination and fits your baggage and connection needs.

For an island stay, you also need to reach the pier, take a boat and get to your accommodation. An airport does not deliver you directly to your chosen beach. Avoid building a tight connection between a ferry and an international flight: the buffer depends on the service, weather and ticket conditions.

From Kampot, compare the road journey to your departure airport before fixing your final night. Ending in Phnom Penh can make flight day simpler, but it is not necessary for every schedule.

A connection or two separate tickets?

A short connection sold as one itinerary and two independently purchased flights need different planning. Before paying, check whether bags are checked through, whether you must change terminals or airports, and what the airline provides if a flight is delayed.

Do not assume a connection is protected just because both flights appear on the same search screen. The ticket and seller's conditions matter. Check any transit formalities with the relevant authorities and airline as well.

Our method before buying

1. Place your first stop and final night on the route.
2. Compare KTI and SAI, then KOS if your coastal stay makes it relevant.
3. Compare return and multi-city tickets for the same dates and baggage.
4. Add transfers and overnight stays imposed by the schedule.
5. Check connection conditions before paying.
