Booking Strategy
For Bangkok to Phnom Penh flights, book 4-6 weeks in advance for optimal pricing. This route sees significant price drops outside Thai and Cambodian holiday periods. Tuesday and Wednesday departures are typically €15-30 cheaper than weekend flights. Use Google Flights to track price trends – set alerts for BKK to PNH. Direct flights are only marginally more expensive than connecting AirAsia routes once you add baggage, making them better value. Avoid booking during Thai holidays (Songkran in April, New Year) when prices spike €40+. Skyscanner often shows prices without taxes initially – always click through to see final EUR price. Cambodia visa ($30) should be factored into trip cost.
Route Tips
- All passengers need a Cambodian visa – get it on arrival ($30 USD, bring exact change) or apply e-visa online 2 weeks before for smoother entry at PNH.
- Bangkok Airways departs from Suvarnabhumi Terminal 3 – verify this isn’t Don Mueang (DMK) when booking, as some budget carriers use the older airport.
- Book morning flights (8:00-10:00) for best weather conditions – afternoon thunderstorms between May-October occasionally cause delays.
- Download the Grab app before arrival in Phnom Penh – it’s the most reliable way to get from the airport and costs half a taxi.
- If combining with Siem Reap, consider Bangkok-Siem Reap on Bangkok Airways (direct) then Siem Reap-Phnom Penh overland (5 hours by bus) – often cheaper than two flights.
