Cheap Flights to Cambodia: Siem Reap & Phnom Penh Deals (2026)
Quick answer
Fares to Cambodia are usually highest in the cool, dry November–February peak season and softer in the hot (March–May) and wet (June–October) months. Since there are very few direct long-haul flights, compare connections through Bangkok, Singapore, Kuala Lumpur, or Ho Chi Minh City, and check both Siem Reap and Phnom Penh as your arrival airport before you book.

Cambodia's dry season commands the highest fares
The comfortable, low-humidity stretch from November to February is when most visitors want to be in Cambodia, and airfare follows that demand upward. The hot pre-monsoon months of March to May and the wetter June–October season see fewer travellers and typically cheaper seats — the wet season in particular tends to mean short afternoon showers rather than all-day rain, so it's a reasonable trade-off for budget-minded trips.
Pick your airport based on your itinerary
| Airport | Best for |
|---|---|
| Siem Reap | Angkor Wat and the temple complex — most visitors' main draw |
| Phnom Penh (PNH) | The capital, and a common starting point for overland or river travel onward |
Note that Siem Reap's international airport moved to a new location outside the city in recent years, so double-check which airport code and location your itinerary actually uses before arranging ground transport. Comparing fares into both Siem Reap and Phnom Penh, rather than fixing on one, often reveals a meaningfully cheaper option.
Expect a connection on long-haul trips
Travellers from Europe, North America, or Australia will almost always connect through a regional hub rather than fly direct. Bangkok, Singapore, and Kuala Lumpur are the most common connection points, and Ho Chi Minh City is a useful option if your trip also touches Vietnam. Comparing a few different connecting hubs on a metasearch, rather than booking the first itinerary shown, is usually where the real savings are.
Combine Cambodia with a neighbouring country
Because Cambodia sits between Thailand and Vietnam, many travellers build a multi-country routing — flying into Bangkok or Ho Chi Minh City and overlanding into Cambodia, or flying an open-jaw ticket that arrives in one country and departs from another. This can work out cheaper than a round trip focused solely on Cambodia, depending on the specific fares available.
Price the total trip, not just the flight
Regional budget carriers serving Cambodia often unbundle checked baggage, seat selection, and sometimes even carry-on weight allowances. Check the add-on costs before assuming the headline fare is the final price, especially if you're bringing gear for temple visits or overland travel.
Set a price alert
Fares into Siem Reap and Phnom Penh can vary a good deal week to week depending on regional demand. A price alert on your route lets you catch a dip in the shoulder months without constantly rechecking.
Track your connecting flight
With most itineraries involving at least one connection, keeping an eye on your inbound flight matters. A live flight tracker shows real-time status before the airport board updates. Track any flight live on ScanFlyGo →
