Alyemda was founded in 1971, four years after the independence of South Yemen and operated a network of flight routes throughout Africa and the Middle East, with its hub at Aden Airport, the former Khormaksar Air Force Base.
ATA also cut down its scheduled operations, most significantly from its former hub at Chicago Midway International Airport.
The airline had a "hub" in Hsinking and was linked by regular flight routes from Harbin, Shamussi (Kiamusze), Kirin, Mukden, Antung, Chinchow, Chengde, Tsitsihar, Hailar, and the Kwantung Leased Territory and Korea areas, for connections with Imperial Japanese Airways (Dai Nippon Koku KK) to Japan itself or foreign routes.
