For decades, Phnom Penh International Airport (PNH) served as Cambodia’s busiest air gateway, connecting millions of passengers to destinations across Asia and beyond. But as Cambodia’s tourism sector grew and international travel surged, the limitations of the old airport became increasingly evident. To address these challenges, the country invested in a new state-of-the-art facility—Techo International Airport (KTI)—which officially began operations in September 2025.
This article provides a comprehensive comparison of Techo Airport vs Phnom Penh Airport, highlighting their differences in location, design, passenger capacity, airlines, facilities, and economic impact. Whether you are a traveler, an expat, or an investor, understanding these differences will help you plan better trips and gain insight into Cambodia’s evolving role in global aviation.
1. The Transition: From Phnom Penh Airport to Techo Airport
For nearly 30 years, Phnom Penh International Airport (PNH) stood as Cambodia’s main international gateway. Located within the city limits, it was convenient but increasingly congested. By 2024, passenger numbers had reached nearly 4.8 million annually, straining the single runway and limited terminal space.
Recognizing the need for modernization, Cambodia partnered with the Overseas Cambodian Investment Corporation (OCIC) to develop Techo International Airport (KTI), a multi-phase mega project designed to support the nation’s long-term growth.
- Closure & Opening Dates:
- Phnom Penh International Airport ceased commercial operations on September 8, 2025.
- Techo International Airport officially opened the next day, on September 9, 2025.
The transition marked a historic moment for Cambodia, signaling not just the move to a bigger airport, but the country’s ambition to position itself as a regional aviation hub.
2. Location and Accessibility: City Center vs Suburban Hub
Phnom Penh International Airport (PNH):
- Located only 10 km west of Phnom Penh city center.
- Easily accessible via short taxi or tuk-tuk rides.
- Travel time: 15–20 minutes under normal traffic conditions.
Techo International Airport (KTI):
- Situated in Kandal Province, about 20–30 km south of Phnom Penh.
- Covers parts of Kandal and Takeo provinces, making it one of the largest airport zones in Southeast Asia.
- Travel time: Approximately 35–45 minutes by car from the city center, depending on traffic.
Getting There:
- Road Access: The government is expanding highways and arterial roads to improve connectivity.
- Public Transport: Plans for dedicated shuttle buses and potential future rail links are underway.
- Taxi Costs: Expect fares to be higher compared to PNH due to the longer distance.
👉 Key takeaway: Phnom Penh Airport was more convenient for city commuters, but Techo Airport is better positioned for expansion and international connectivity.
