Techo International Airport at a glance

Techo International Airport (KTI) is the new main airport for Phnom Penh and the largest airport in Cambodia. It opened in 2025 and took over commercial flights from the old Phnom Penh International Airport, which used the code PNH. If you are flying to or from Cambodia's capital on a scheduled airline, this is almost certainly where you will land.

The name comes from "Techo", a historic Khmer title given to army commanders.

Location: south of Phnom Penh

The airport is in Kandal Steung District of Kandal Province, south of Phnom Penh. It is further from the city than the old airport, so the trip into town takes longer, often more than an hour by road depending on traffic and where you are staying.

Terminal design and facilities at Techo

Passengers use a single terminal designed by the British firm Foster + Partners. A sweeping roof held up by tree-like steel columns lets daylight into the halls, and planting runs through the concourse. A large golden Buddha statue in the terminal has become a popular photo spot. The airport also draws power from an on-site solar farm.

Inside you will find duty-free shops, local souvenirs, food outlets and the usual departure facilities. The single runway is 4,000 metres long, long enough for the largest passenger jets.

Airlines at Techo International Airport

KTI is the hub for Cambodian carriers including Air Cambodia, Cambodia Airways and Sky Angkor Airlines, and a base for AirAsia Cambodia. Many regional and long-haul airlines also serve the airport, including Vietnam Airlines, Thai Airways, Singapore Airlines, Emirates and Qatar Airways, giving good links across Asia and connections further afield.

Getting from Techo Airport to Phnom Penh

The Airport Express Bus, run by Phnom Penh City Bus, is the budget choice. It runs daily from early morning until late evening, departing frequently from outside the arrivals hall, and follows a route into the city centre with stops along the way. Taxis and ride-hailing cars are the faster door-to-door option.

What to see in Phnom Penh

Popular sights in the capital include the Royal Palace and Silver Pagoda, the National Museum of Cambodia and the riverside promenade where the Tonle Sap meets the Mekong. The Tuol Sleng Genocide Museum and the Choeung Ek memorial tell the story of the country's recent history.

Travel tips for Techo International Airport

Allow extra time to reach the airport, since it is further out than the old one. Double-check that your ticket shows KTI rather than PNH. The express bus stops running at night, so book a car for late departures.
