The Department of Airports (DOA, Thai: กรมท่าอากาศยาน) is a Thai government department under the Ministry of Transport. It operates 28 civil airports throughout the country. The department was split off from the Department of Civil Aviation in 2015, part of a restructuring response to ICAO's downgrading of Thailand's aviation safety rating. The other agency that previously formed part of the old department is the Civil Aviation Authority of Thailand.
