Domestic flights in Cambodia
Domestic flights in Cambodia are limited but can save time between Phnom Penh, Siem Reap and Sihanoukville. Here's when to fly and when to take the road instead.
In this guide
Cambodia is small enough that most travellers go overland. However, domestic flights can save time on certain routes, especially if you're on a short trip.
Main routes
- Phnom Penh to Siem Reap: the most common domestic route, with a short flight time.
- Siem Reap to Sihanoukville: useful for combining Angkor with the islands.
- Phnom Penh to Sihanoukville: sometimes available, though the expressway has made road travel quicker.
Routes and airlines change frequently, so check current schedules.

Combining with international flights
Some travellers fly into Siem Reap and out of Phnom Penh (or the reverse), using a domestic flight or overland journey in between. This avoids backtracking and saves time.
