JAT was forced to survive on six domestic lines. This caused further rationing of fuel, difficulties in procuring spare parts, and the cancellation of all flights to Eastern European destinations. In 1949, Yugoslavia was faced with a dire international position: isolated both by the West and the East. The airline was officially renamed to Jugoslovenski Aerotransport ( JAT) on 1 April 1947. Three Douglas C-47 Skytrain and three Junkers Ju 52 were converted to carry passengers. Consequently, preparations were made for the formation of an air transport company. In 1946, it was apparent that the Yugoslav Air Force could not be involved in the nation's post-war build-up of civil aviation. the name was changed to Jugoslovenski Aerotransport (abbreviated JAT "Yugoslav Air Transport"), then to JAT Yugoslav Airlines and finally to Jat Airways on 8 August 2003. JAT Yugoslav Airlines was launched on 1 April 1947 and replaced Aeroput in 1948. Aeroput continued to operate until the start of World War II. In 1937, the expansion of international routes and an increase in passenger numbers enabled Aeroput to acquire the Lockheed Model 10 Electra. Their first international flight was in 1929 between Belgrade and Graz. JAT traces its heritage back to 1927 when Aeroput, the first civil airline in Yugoslavia was founded. JAT Yugoslav Airlines McDonnell Douglas DC-10-30 at Belgrade Nikola Tesla Airport, 2003 The change marked the end of 66 years of the JAT brand. Certain assets, such as the ATR 72 aircraft, would be transitioned to Air Serbia, while other assets (such as the 737-300s) would remain in JAT Airways branding until retired. On 1 August 2013, the Government of Serbia and Etihad Airways entered into an agreement that reorganized the operations of Jat Airways, and renamed it Air Serbia after the transitional period ended. Jat Airways was owned by the government of Serbia and had 1,250 employees. Flight operations were based at Belgrade Nikola Tesla Airport, and the airline operated scheduled services to 72 international destinations, outside the areas formerly part of Yugoslavia, as well as charters and wet leases. Jat Airways and their predecessors were one of the oldest airlines still in operation. The airline was renamed again on 8 August 2003. After resuming flights in 1947, the airline was renamed Jugoslovenski Aerotransport (abbreviated JAT, pronounced "Yugoslav Air Transport") on 1 April 1947. Founded in 1927 as Aeroput, the airline ceased operations during World War II.
