Frequently asked questions

What is the IATA code for Phnom Penh's new airport?
Phnom Penh's new airport uses the IATA code KTI for Techo International, opened in 2025. The legacy city-centre airport PNH has been progressively retired as scheduled traffic shifted south. Search KTI on Flightmussy for the freshest schedules now that all major carriers have migrated their Phnom Penh service to the new field.
How far is Techo airport from Phnom Penh?
KTI sits in Boeng Khyang district about 30 km south of central Phnom Penh, roughly a 45-60 minute drive depending on traffic. A new expressway link makes it faster than the old PNH city-centre runs at peak times. Flightmussy is free and needs no signup, so you can plan transfers easily.
Which low-cost carriers serve KTI?
AirAsia and Thai AirAsia connect KTI with Kuala Lumpur and Bangkok, VietJet Air runs Ho Chi Minh City and Hanoi, Scoot covers Singapore and seasonal Chinese LCCs operate when demand allows. Flightmussy surfaces these options prominently because Google Flights frequently de-prioritises low-cost carriers in favour of legacy alliances.
When should I book flights to Phnom Penh?
Book six to eight weeks ahead for the November-February dry-season peak. Khmer New Year in mid-April spikes domestic and regional fares. Wet season May through October is cheapest, with September the value sweet spot. The free 12-month Flightmussy fare heatmap pinpoints the exact week each year worth booking.
