Thai AirAsia (SET: AAV, Thai: ไทยแอร์เอเชีย) is a joint venture of Malaysian low-fare airline AirAsia (Thai: แอร์เอเชีย) and Thailand's Asia Aviation. It serves AirAsia's regularly scheduled domestic and international flights from Bangkok and other cities in Thailand.
Thai AirAsia was once the only low-cost airline operating both domestic and international flights from Suvarnabhumi Airport. However, the airline transferred all operations in Bangkok from Suvarnabhumi Airport to Don Mueang International Airport effective 1 October 2012.
