In 1944, a group of businessmen founded Iran's first flag carrier under the name of Iranian Airways. Operations covered domestic and regional passenger and freight services plus a weekly freight service to Europe. The fleet consisted of Douglas DC-3s initially, supplemented by Douglas DC-4 and Vickers Viscount aircraft, later on. In 1954, the privately owned airline Persian Air Services (PAS) was established, which initially operated only freight services, followed by passenger operations between Tehran and other major cities in Iran. In 1960, PAS initiated service to several European destinations, including Geneva, Paris, Brussels and London, using Douglas DC-7C aircraft, leased from Sabena.
