Myanma Airways operates Fokker 27 and Fokker 28 aircraft on local routes, and has a very poor operational standard. It's govermental.
Myanmar Airways International (MAI) operates A320 and A321 on international routes and has a flawless safety record.
It is at least partly internationally owned and managed.
Local flights are also offered by Air Mandalay and AirBagan who are of good standards.
