Kuala Lumpur to Siem Reap is the easy way to reach the temples of Angkor — a short non-stop of a little over two hours, now landing at Cambodia’s modern Siem Reap-Angkor International Airport, which opened in 2023 to replace the old in-town field. This guide covers who flies the route non-stop, what a fair return fare looks like in ringgit, and how to get from the new airport to town.
Route: Kuala Lumpur (KUL) → Siem Reap-Angkor International (SAI)
Distance: approximately 1,210 km (750 miles)
Non-stop flight time: about 2h 10m
Direct flights: Yes — AirAsia flies non-stop from Kuala Lumpur to Siem Reap, joined since late 2025 by Firefly (Malaysia Airlines’ sister carrier) on a Boeing 737. Between them there are around a dozen or more departures a week.
Fares from Kuala Lumpur to Siem Reap (MYR)
Siem Reap runs on Cambodia’s tourist calendar: the cool, dry season from November to February is the busiest and priciest, while the wet months from May to October are the cheapest and quietest at the temples. As a short route flown mainly by low-cost and hybrid carriers, fares move more with the promo calendar and how far ahead you book than with fuel. The figures below are typical economy return fares in ringgit.
| Month | Demand |
|---|---|
| January | high |
| February | high |
| March | medium-high |
| April | high (Khmer New Year) |
| May | low |
| June | low-medium |
| July | medium (school break) |
| August | medium |
| September | low |
| October | low-medium |
| November | high |
| December | very high |
We do not quote a target fare for this route. Our price tracking holds no recorded observations for it, so a “typical” or “good deal” figure here would be an estimate dressed up as a measurement — so this page leaves it out rather than guess. The seasonal pattern above is the part we can stand behind; check the live fare for the number.
Airlines on this route
Non-stop (about 2h 10m):
- AirAsia — the mainstay of the route and usually the cheapest headline fare; base tickets are cabin-bag only, so add a checked bag if you need one.
- Firefly — part of the Malaysia Airlines group, flying the route non-stop on a Boeing 737 since late 2025, typically a few times a week with a fuller-service product.
With non-stops available, there is little reason to connect — a one-stop routing through Bangkok, Ho Chi Minh City or Singapore only adds hours and rarely saves money. Compare the all-in price including baggage, as AirAsia’s lowest fares carry no checked bag while Firefly’s fares generally include more.
When to book & how to save
- Book 4–10 weeks ahead for the best fares; on a short leisure route, seats close to departure are usually the most expensive.
- Travel in the green season (May–October) for the lowest fares — the rain comes in short afternoon bursts and the temples are far quieter.
- Avoid the November–February peak and Khmer New Year (mid-April), when both demand and prices are highest.
- Watch AirAsia flash sales, which regularly beat everything else if your dates are flexible.
- Add baggage upfront: buying a checked bag at booking is far cheaper than at the airport, and it often makes Firefly’s all-in fare competitive with AirAsia’s.
Arriving in Siem Reap
Flights land at Siem Reap-Angkor International Airport (SAI), which opened in 2023 about 40–45 km east of the city, near Sotr Nikum — considerably further out than the old airport, so plan the transfer in. There is an airport shuttle bus into town (a few US dollars, roughly RM 15–RM 30), while a private taxi or hotel car runs about RM 90–RM 150 (around US$20–35) and takes 50 minutes to just over an hour depending on traffic. Many hotels offer a free or low-cost pickup if you ask when booking — worth arranging in advance given the distance.
Frequently asked questions
How long is the flight from Kuala Lumpur to Siem Reap?
The non-stop flight takes about 2 hours 10 minutes, covering roughly 1,210 km. It is a comfortable short hop, with the fuller-service and low-cost options both getting you to the gateway of Angkor in a single flight.
Are there direct flights from Kuala Lumpur to Siem Reap?
Yes. AirAsia flies non-stop between Kuala Lumpur (KUL) and the new Siem Reap-Angkor International (SAI), and Firefly — part of the Malaysia Airlines group — added non-stop service on a Boeing 737 in late 2025. There is no need to connect for this route.
How much does it cost to fly from Kuala Lumpur to Siem Reap?
A typical economy return runs about RM 510–RM 980 depending on the season. Strong deals land around RM 500–RM 580 return, while the November–February high season and the December peak sit toward the top of the range. One-way promo fares can fall near RM 230.
What is the cheapest month to fly from Kuala Lumpur to Siem Reap?
May, June and September are usually the cheapest months to fly. Avoid the November–February dry season, the December peak and mid-April (Khmer New Year), which are the busiest and most expensive.
Which airlines fly from Kuala Lumpur to Siem Reap?
Two carriers fly the route non-stop: AirAsia (low-cost, usually the cheapest) and Firefly (Malaysia Airlines group, a fuller-service product added in late 2025). Compare the all-in price with baggage, as AirAsia’s base fares are cabin-bag only.
Which airport do I fly into in Siem Reap?
You arrive at Siem Reap-Angkor International Airport (SAI), opened in 2023 about 40–45 km from the city and the temples. It replaced the old in-town airport, so it is further out — budget 50 minutes to just over an hour for the transfer into Siem Reap.
How far in advance should I book Kuala Lumpur to Siem Reap flights?
Aim to book 4 to 10 weeks ahead for the best fares. On this short leisure route prices tend to rise close to departure, especially over the November–February high season, so booking early — and catching an AirAsia sale — usually wins.
Is it cheaper to fly on weekdays?
Often, yes. Midweek departures (Tuesday to Thursday) are typically a little cheaper than Friday–Sunday, and pairing two weekday legs can trim RM 40–RM 120 off a return. With Firefly flying only certain days, being flexible also gives you more choice of fares.
