Fares from Kuala Lumpur to Phnom Penh (MYR)
This is a short regional route, so fares are driven more by how far ahead you book and by the AirAsia promo calendar than by long-haul seasons. Prices firm up around Khmer New Year (mid-April), the year-end holidays and the Malaysian school breaks, and are softest in the quieter shoulder months. The figures below are typical economy return fares in ringgit; the cheapest are low-cost carriers booked well ahead.
| Month | Demand |
|---|---|
| January | medium |
| February | medium |
| March | low-medium |
| April | high (Khmer New Year) |
| May | low |
| June | medium (school break) |
| July | low-medium |
| August | low |
| September | low |
| October | low-medium |
| November | medium |
| 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We do not quote a target fare for this route.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 2 hours):
- AirAsia — the low-cost workhorse of the route, usually the cheapest headline fare; hand baggage only on the base fare, so add a bag if you need one.
- Malaysia Airlines — full-service non-stop with checked baggage, meal and Enrich miles included; the comfortable choice.
- Cambodia Airways — Phnom Penh-based carrier flying the route non-stop, often competitively priced.
Because all three fly the same short sector, there is rarely any reason to take a connection — a one-stop routing through Bangkok or Ho Chi Minh City only adds hours for little or no saving. Compare the all-in price with baggage rather than the headline fare, since AirAsia’s cheapest tickets are cabin-bag only.
When to book & how to save
- Book 3–8 weeks ahead for the best low-cost fares; on such a short route, last-minute seats are usually the priciest.
- Watch the AirAsia sales — flash promos on this sector regularly beat everything else if your dates are flexible.
- Avoid Khmer New Year (mid-April) and late December, when both leisure demand and fares peak.
- Add baggage upfront: buying checked bags at booking is far cheaper than at the airport, and it often makes Malaysia Airlines’ all-in fare competitive with AirAsia’s.
- Fly midweek — Tuesday to Thursday departures are typically cheaper than Friday–Sunday on this route.
Arriving in Phnom Penh
Flights now land at Phnom Penh Techo International Airport (KTI), the new gateway that opened in September 2025 about 20 km south of the city near Kandal province — it replaced the old in-town airport. It is further out than the old field, so allow extra time: a metered airport taxi or ride-hailing car into central Phnom Penh takes roughly 40–60 minutes and costs in the region of RM 50–RM 90 (around US$12–20) depending on traffic and where you are staying. Shuttle-bus and coach links into the city centre are also being rolled out; agree the fare or use a metered app before you set off.
