Cambodia's third international airport, located in Sihanoukville, Cambodia
From Wikipedia, the free encyclopedia
Sihanouk International Airport (formerly Sihanoukville International Airport; Khmer: អាកាសយានដ្ឋានអន្តរជាតិខេត្តព្រះសីហនុ) (IATA: KOS, ICAO: VDSV), located 20 kilometres (12 mi) east of Sihanoukville City in Sihanoukville Province, is Cambodia's third largest international airport.[2] It is named, like the province itself, after King Norodom Sihanouk. The airport is also known as Kang Keng Airport (Khmer: អាកាសយានដ្ឋានកងកេង). The IATA code KOS is derived from Sihanoukville's alternative name, "Kampong Som".[3]

History
The airfield was originally constructed in the 1960s with assistance from the Soviet Union.[4] After a long period of dormancy during and after the Khmer Rouge era, the airport formally reopened on 5 January 2007.[5] The runway was extended to a length of 3,300 metres (10,827 ft) in order to accommodate 4E class aircraft. The 2 existing taxiways were widened and a cargo apron for 4E class aircraft was added.[6] However, after the crash of PMTair Flight U4 241 in June 2007 shortly before landing, scheduled passenger flight service to the airport was discontinued until 2011.[7]
Cambodia Angkor Air started a tri-weekly service from Angkor International Airport in Siem Reap on 14 December 2011. The service was further adjusted to continue Phnom Penh as well, operating a triangle route, Siem Reap-Sihanoukville-Phnom Penh-Siem Reap, starting on 31 March 2013. Starting in September 2013, the airline was scheduled to provide a Siem Reap-Sihanoukville route twice daily during the high peak season.
