It was established in 1990 and is wholly owned by the Iranian Air Force. Regular domestic flights include daily flights from its base at Tehran's Mehrabad airport to Mashhad, Kish Island, Assoulyeh and its aircraft also make regular appearances at Shiraz. It is notable for being the very last airline in the world to operate the Boeing 707 in passenger service. These particular aircraft are ex air-to-air tanker 707s, delivered in 1976 and pressed into passenger service due to sanctions by the USA which have stopped Iran acquiring new aircraft since 1979.
