A New 4F Hub for Cambodia’s Capital
Techo International Airport sits in Kandal province just south of Phnom Penh and is designed as a 4F category facility, the highest class in the International Civil Aviation Organization’s system for commercial airports. Publicly available information indicates that this rating allows the airport to accommodate the world’s largest aircraft, including the Airbus A380 and Boeing 747-8, positioning Phnom Penh to handle long-haul intercontinental services that were difficult to sustain at the older, land-constrained site.
Official aeronautical documentation and operator data show that commercial operations at Techo International Airport commenced on 9 September 2025, with all scheduled flights progressively transferred from Phnom Penh International Airport in the days around that date. The former airport, commonly known as Pochentong, closed to regular passenger traffic once the transition was completed, confirming Techo International Airport as the capital’s primary international gateway.
Developed on a site of around 2,600 hectares in Kandal and Takeo provinces, the new airport gives Phnom Penh substantially more room to expand runways, taxiways and terminal infrastructure than was possible at its predecessor. Information from the project company and partner reports highlights that this additional capacity is intended to future-proof the capital’s air transport needs as tourism and business travel continue to grow.
Tourism Recovery Drives Demand for Connectivity
Cambodia’s decision to invest in a new capital airport is closely linked to the rapid rebound in visitor numbers. Tourism statistics compiled by Cambodia’s Ministry of Tourism show that the country welcomed about 6.7 million international tourists in 2024, an increase of roughly 23 percent compared with 2023 and slightly above pre-pandemic levels recorded in 2019. Regional assessments from ASEAN tourism outlook reports also place Cambodia among the more robust post-pandemic performers in Southeast Asia.
Government projections referenced in national news coverage anticipate that arrivals could climb to around 7.5 million in 2025, barring external shocks. Much of this demand is driven by regional travelers from ASEAN and China, which together account for the majority of visitors, but long-haul source markets in Europe and North America are gradually returning as connectivity improves. The scale of Techo International Airport is intended to match this trajectory by enabling more frequent flights and new routes.
Cambodia’s broader tourism strategy emphasizes diversification beyond Angkor and Siem Reap, with Phnom Penh, coastal provinces, and emerging eco-tourism areas all targeting higher-spend segments. Enhanced air links through the capital are regarded in public reports as critical to attracting premium leisure visitors, meetings and incentives groups, and investors in large-scale tourism infrastructure.
Replacing Pochentong and Integrating a Three-Airport Network
The opening of Techo International Airport completes a major reconfiguration of Cambodia’s airport network. Siem Reap’s old town airport closed in 2023, when the larger Siem Reap–Angkor International Airport opened farther from the temples to reduce environmental pressures and accommodate growth. In Phnom Penh, the shift from Pochentong to the new site south of the capital follows a similar logic of capacity expansion and urban planning.
According to operator and tourism board information, Cambodia now effectively operates a three-node international system: Techo International Airport serving the capital, Siem Reap–Angkor International Airport for the country’s principal heritage destination, and Sihanoukville International Airport for the southern coastline. Additional facilities, such as the newer Dara Sakor Airport in Koh Kong province, are gradually being positioned to support niche and resort-focused tourism.
By concentrating most scheduled international traffic into modern, higher-capacity airports, Cambodia aims to streamline passenger experience while aligning with regional safety and service benchmarks. This network design is also expected to support more coherent route development, allowing airlines to link Phnom Penh, Siem Reap and Sihanoukville with multi-stop itineraries that better distribute visitors across the country.
Airline Moves Signal Emerging Hub Potential
Route announcements by carriers underline Techo International Airport’s role as a growing regional node. Information published by Qatar Airways shows that the airline shifted its Phnom Penh operations to Techo International Airport on 9 September 2025, maintaining a direct link between the Cambodian capital and Doha. This connection provides one-stop access between Cambodia and Europe, the Middle East and parts of Africa, supporting the country’s ambition to draw more long-haul visitors.
Operator updates and promotional material indicate that other regional airlines have also transitioned services to the new airport, with gradually expanding frequencies from major Asian hubs. Techo International Airport’s 4F status and longer runway length are seen in public documentation as important assets for attracting additional widebody operations and potential new entrants from Northeast Asia and the Gulf.
Beyond scheduled flights, the airport’s design is intended to support cargo growth alongside passenger traffic, which could open fresh opportunities for Cambodia’s export-oriented sectors. This, in turn, has potential knock-on benefits for business travel and mixed-purpose trips, strengthening Cambodia’s case as both a leisure and commercial destination.
Infrastructure, Investment and the Future of Cambodian Travel
Techo International Airport is one of Cambodia’s largest infrastructure investments, developed by Cambodia Airport Investment Co. in partnership with experienced international operators. Publicly available project figures place its total cost at around 1.5 billion US dollars, reflecting the scale of runways, terminals, ground transport links and support facilities built on the expansive greenfield site.
In parallel with the airport, authorities and developers have advanced road links, logistics zones and hospitality projects in the wider Phnom Penh area. Economic and tourism assessments suggest that this ecosystem of infrastructure is essential to convert improved connectivity into higher visitor spending, job creation and broader regional development.
Tourism outlooks for Cambodia nonetheless highlight external risks, including regional geopolitical tensions and shifting travel patterns, which could influence how quickly new capacity is filled. Even so, the combination of a modern capital airport, upgraded gateways at Siem Reap and Sihanoukville, and a steady recovery in visitor numbers positions Cambodia to compete more effectively within the ASEAN tourism landscape.
For travelers, the shift to Techo International Airport means a different entry point to Phnom Penh and a preview of the country’s longer-term ambitions. As airlines bed in their operations and connectivity deepens, the new hub is set to play a central role in how Cambodia connects with the world and how the world experiences Cambodia.
