Answer for the mystery airline in Odds and Ends.
Air Serbia is the flag carrier of Serbia, headquartered in Belgrade. Founded in June 17, 1927 as Aeroput.
Aeroput was among the first civilian aircraft carriers, being the 10th airline company founded in Europe and the 21st in the world. The airline ceased to exist during World War II in Yugoslavia, but was renewed after the war under the new name Jugoslovenski Aerotransport (abbreviated JAT; English: Yugoslav Air Transport) until it was renamed and rebranded on October 26, 2013.
