Cheapest months to fly to Siem Reap
Fares into Siem Reap-Angkor International Airport follow a pretty predictable rhythm once you know what to look for. The cheapest windows tend to cluster around May and June, right before the wet season kicks in and most tourists tap out. Prices spike hard from November through February — that's peak dry season, and every temple-chaser on the planet seems to land at once. Chinese New Year adds another surge in late January or early February depending on the year. Book during those shoulder months and you'll often find fares that make the trip feel almost accidental.
Why visit Siem Reap?
Angkor Wat is the obvious draw, and honestly, it deserves the hype. But people who come just for the temples usually end up staying longer than planned. The food scene around Pub Street and the Old Market is genuinely good — fish amok, lok lak, freshly pressed sugarcane juice at 7am. The town itself is small enough to get through by tuk-tuk for almost nothing. Beyond the temples, Tonle Sap Lake offers a completely different side of Cambodia — floating villages, bird sanctuaries, local fishing life that hasn't been staged for anyone. There's also a growing creative scene, with independent galleries and boutique stays run by local designers. It's not a business hub by any stretch, but remote workers are showing up here for the low cost of living and surprisingly decent wifi in the newer cafes.

Tips for getting a cheap fare to Siem Reap
Flying in from Bangkok is usually your best bet for cheap connections — both BKK and DMK serve Siem Reap, so check both airports before booking. If you're coming from further out, routing through Ho Chi Minh City or Hanoi often beats flying direct from Europe. I'd aim to book six to eight weeks out for the best fares, and set a price alert the moment you start thinking about the trip. Visa on arrival is straightforward and costs $30 USD — bring crisp bills, the border officers are picky. The local currency is the riel, but USD is accepted almost everywhere.
Frequently asked questions about cheap flights to Siem Reap
What's the cheapest month to fly to Siem Reap?
May to September (low/green season) typically offers the lowest fares, though it's the rainy season. October and November are also budget-friendly with better weather as the monsoon ends.
How far in advance should I book to get cheap flights to Siem Reap?
Book 2-3 months in advance for optimal prices, though 6-8 weeks ahead is also reasonable. Avoid booking last-minute unless you find flash sales, as prices typically increase closer to departure.
Are there cheaper nearby airports to fly into instead of Siem Reap?
Bangkok's Suvarnabhumi Airport (BKK) often has cheaper flights than Siem Reap (SAI), and you can travel overland to Cambodia by bus or train for $15-30. However, direct flights to SAI may offer better overall value when factoring in transfer costs.

What are the visa basics for visiting Cambodia?
Most visitors need a visa; Cambodia offers 30-day tourist e-visas (online for ~$36) or visa-on-arrival. Citizens of ASEAN countries, France, Germany, Japan, and a few others get visa-free entry for 14-30 days.
