Cambodia has officially entered a new chapter in aviation history with the opening of Techo International Airport on September 9, 2025, replacing the iconic Pochentong International Airport after more than half a century of service.
Historic Airport Transition Transforms Phnom Penh’s Aviation Landscape
The transition from Pochentong to Techo International Airport represents one of Southeast Asia’s most significant aviation infrastructure developments in 2025. Cambodia set September 9, 2025, for the official operation of Techo International Airport, with Phnom Penh International Airport closing on the night of September 8, 2025.
This monumental shift positions Cambodia as a major player in regional aviation, with the new airport designed to handle substantially more passengers and larger aircraft than its predecessor.
Techo International Airport: World-Class Specifications and Capacity
The new airport showcases impressive specifications that place it among Asia’s premier aviation facilities:
Phase 1 Features (2025)
Techo International Airport is classified as a 4F-level airport, the highest level in the world, capable of handling approximately 13 million passengers a year in the first phase. The first phase features a 4-kilometer runway designed to accommodate over 15 million passengers annually by 2025.
Aircraft Capabilities
The airport can receive giant aircraft up to Airbus A380-800 and Boeing 747-800. This capability positions Cambodia to attract major international carriers operating wide-body aircraft on long-haul routes.
Future Expansion Plans
The first phase can handle 13 million passengers a year, whilst the second phase is set to increase this to 30 million. All together, the three phases will be able to handle 50 million passengers a year.
The second phase will see the addition of two more runways, boosting the airport’s capacity to 30 million passengers by 2030, while the third and final phase by 2050 will expand the airport further.
Investment and Infrastructure Development
The project represents a massive investment in Cambodia’s future:
- Total Investment: The investment budget for the first phase is 1.5 billion dollars, excluding the airport land.
- Land Area: The total land allocated for the airport covers 2,600ha, with 700ha dedicated to infrastructure.
- Location: Situated in Kandal province, approximately 30 kilometers south of Phnom Penh
The End of an Era: Pochentong’s Legacy
Pochentong International Airport served Cambodia for over 60 years, opening in the 1960s and witnessing the country’s dramatic historical changes. From the civil war and Khmer Rouge period to the economic boom of recent decades, Pochentong has been Cambodia’s primary gateway to the world.
Under Vinci Airports’ management, Pochentong underwent significant modernizations to meet international standards, but the growing demand for air travel and cargo services necessitated a completely new facility.
Strategic Regional Positioning
The opening of Techo International Airport is part of Cambodia’s broader strategy to establish itself as a regional aviation hub, competing with established centers like Bangkok, Ho Chi Minh City, and Singapore.
Economic Impact
The new airport is expected to:
- Attract more international airlines
- Boost tourism capacity significantly
- Enhance trade connectivity across Southeast Asia
- Create thousands of employment opportunities
- Stimulate economic development in the southern corridor
Transportation and Accessibility
While Techo International Airport offers world-class facilities, its distance from Phnom Penh presents new challenges and opportunities:
- The government is developing express highway connections
- Plans include a future railway line connecting the airport directly to the city center
- The Phnom Penh-Sihanoukville expressway provides improved connectivity
- New urban ring roads complement the transportation network
First Commercial Operations and Testing
On August 15, 2025, an A320 plane from Air Cambodia became the first commercial plane to successfully test a touch-and-go landing at the new airport. This successful test flight marked a crucial milestone in the airport’s preparation for full operations.
Official Inauguration Ceremony
The official inauguration ceremony of Techo International Airport took place on October 20, 2025, under the chairmanship of Prime Minister Hun Sen.
What Happens to Pochentong Airport?
The closure of Pochentong raises important questions about the future use of this strategic urban site. Located close to Phnom Penh’s center, the former airport presents opportunities for:
- Special economic zone development
- International convention center
- Mixed-use urban development
- Green space and recreational facilities
Cambodia’s Aviation Future
The transition to Techo International Airport represents more than just a change of location—it symbolizes Cambodia’s transformation into a modern, globally connected nation. With capacity to eventually handle 50 million passengers annually, the airport positions Cambodia to become a significant player in Asia-Pacific aviation.
The move from Pochentong to Techo International Airport marks the end of one era and the beginning of another, reflecting Cambodia’s journey from a war-torn nation to a rapidly developing economy ready to compete on the global stage.
