Phnom Penh International Airport — Phnom Penh (Pou Senchey), Cambodia

Cambodia's capital relies on Phnom Penh International Airport, still labeled PNH in booking systems, though the country's air traffic is gradually shifting toward the newly built Techo International Airport intended to eventually take over the bulk of its role. Locals often call the older facility Pochentong, after the suburb a few kilometers west of downtown where it sits. Cambodia's tourism boom, driven substantially by visitors bound for the temples of Angkor near Siem Reap, has historically routed a large share of arriving travelers through PNH before their onward domestic connections. The airport also handles significant business travel tied to the garment manufacturing and construction sectors that have powered Cambodia's economic growth since the early 2000s. A single main terminal, modernized in stages over the years, manages both international and domestic flights, and regional carriers from across Southeast Asia maintain service alongside longer connections to East Asia and the Gulf.
