Starting Sept. 9, all Vietnam Airlines flights to and from Phnom Penh will depart from the new Techo International Airport (KTI), replacing the city's old Phnom Penh International Airport (PNH).

Located more than 20 km south of downtown Phnom Penh, Techo International Airport meets the International Civil Aviation Organisation (ICAO)'s 4F standards. The new facility is over 30 km away from the old airport, with estimated travel times of 40 minutes to the city center and 50 minutes between the two airports, according to Cambodia's civil aviation authorities.

During the initial phase of operations at Techo International Airport, Vietnam Airlines advised passengers to carefully check departure and arrival airport details when booking and issuing tickets. The carrier also recommended arriving at least three hours before departure for international flights and regularly cheking its latest updates.

Vietnam Airlines confirmed that all tickets issued before Sept. 9, 2025 with the code PNH will be automatically updated to KTI while retaining the original flight numbers. Passengers wishing to adjust their itineraries may do so under the airline's rebooking policy.
