Is there a direct flight from Kota Kinabalu to phnom penh??

Thanks,

There's no direct flight from Kota Kinabalu (BKI) to Phnom Penh (PNH). The cheapest way is via KUL with AirAsia. AirAsia is a point-to-point budget airline, so make sure you have at least 4 hours for stopover in KUL in case of delays on the first leg of the flight.
