Southeast Asia Airport Report (2025 Edition)

Welcome to the 2025 edition of the Southeast Asia Airports Report. This is a summary of airports planned, under construction, and other airport news in Southeast Asia over the past year.

🇰🇭 Cambodia

Techo International Airport (KTI)

Techo International Airport is the under-construction future airport of Phnom Penh. I keep seeing reports that it will be the 9th-largest airport in the world by land size, but I am not sure of this. The land size is reported at 2,600 hectares (26 sq km), which wouldn’t put it in the top 10. For a regional comparison, Suvarnabhumi Airport is 3,240 ha. Top 10 or not, KTI (the official IATA code) will be a big airport.

The airport construction has received positive international coverage, partly because Foster + Partners designed it. The airport was featured in the CNN list of 11 architecture projects set to shape the world in 2025.

The most recent report states that the airport will open in July this year, making it the largest new airport opening for 2025 in Southeast Asia.

The new airport is 24 km from the city centre, but the proposed airport rail link has not been finalised.

Siem Reap-Angkor International Airport

Siem Reap-Angkor International Airport has been open for over a year now. Chinese state media reported that the airport handled more than 14,000 flights in its first year.

Australian media remarked that it is "cavernously empty".

Like the new Phnom Penh Airport, this new airport is far outside the city centre with no airport rail link.

Dara Sakor International Airport

Dara Sakor International Airport in Koh Kong Province began trial operations with the arrival of a chartered flight from Phnom Penh International Airport.

Koh Rong International Airport

Koh Rong is an island off the coast of Sihanoukville. Construction of the airport began in January 2024, though there haven’t been any updates since. 

There are big development plans for the island, and the builder of the airport is also building most of the new developments on the island.

Sihanoukville International Airport

The construction of a new terminal at Sihanoukville International Airport is expected to be completed by 2026.

Battambang Airport

There is still talk of reviving Battambang Provincial Airport, which has not been in service for more than three decades.

Mondulkiri Airport

A new airport is planned for Mondulkiri province, and a private firm was selected to study the construction. This project appears to have stalled, with no updates from local media.

🇮🇩 Indonesia

The biggest airport news of 2024 in Indonesia was the revoking of the international status of 17 airports, from previously 34 international airports.
