Jat Airways (stylized as JatAirways; ) was the national flag carrier and largest airline of Yugoslavia and later Serbia and Montenegro and Serbia. Founded in 1927 as Aeroput, the airline ceased operations during World War II. After resuming flights in 1947, the airline was renamed Jugoslovenski Aerotransport (abbreviated JAT, ; "Yugoslav Air Transport") on 1 April 1947. The airline was renamed again on 8 August 2003. Jat Airways and their predecessors were one of the oldest airlines still in operation. 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 was owned by the government of Serbia and had 1,250 employees. 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. 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. The change marked the end of 66 years of the JAT brand. History Aeroput JAT traces its heritage back to 1927 when Aeroput, the first civil airline in Yugoslavia was founded.

Consequently, preparations were made for the formation of an air transport company. Three Douglas C-47 Skytrain and three Junkers Ju 52 were converted to carry passengers. The airline was officially renamed to Jugoslovenski Aerotransport (JAT) on 1 April 1947. In 1949, Yugoslavia was faced with a dire international position: isolated both by the West and the East.
