Overview

  • The new airport received its first commercial flights on September 9, including an Air Cambodia service from China welcomed with a water salute.
  • Initial capacity is about 13 million passengers per year, with targets of 30 million after 2030 and up to 50 million by 2050.
  • Phnom Penh’s old airport has closed to commercial traffic, with the site to be maintained for military use and emergency operations.
  • The project was developed by CAIC, a subsidiary of OCIC, in joint venture with the State Secretariat of Civil Aviation, built by a major Chinese construction firm, and designed by Foster + Partners.
  • Civil aviation officials put the first-phase cost at $2 billion after earlier estimates of $1.5 billion, while NGO STT reports roughly 2,000 households were affected by evictions that authorities say are almost resolved.
