Cambodia’s New Aviation Landscape in 2025

Techo International Airport (KTI): Phnom Penh’s Modern Gateway

If you haven’t been to Cambodia yet — or if it’s been a few years — you’re in for a surprise. Phnom Penh now operates from a brand-new international airport: Techo International Airport (KTI). Officially opened in September 2025, this airport replaces the long-serving Phnom Penh International Airport (PNH).

Here’s what makes KTI special:

  • Modern facilities, from expanded terminals to smoother immigration flow
  • Better runway capacity to handle long-haul flights
  • Strategic design, built to accommodate Cambodia’s future as a regional aviation hub

The relocation to KTI is a huge deal for travelers. Many flight guides online still reference the old airport (PNH), so if you’re booking flights, make sure the airport code reads KTI.
