Air Serbia (JU, Belgrade) has made initial preparations for its planned transition to an all-Airbus (AIB, Toulouse Blagnac) fleet after Belgrade recently approved a down payment for the carrier's first five of ten A319-100 jets. According to EX-YU Aviation News, the renewed Serbian national carrier will launch new routes in the following order: Abu Dhabi Int'l (October 27), Banja Luka (December 1), Prague Ruzyne (December 1), Bucharest Otopeni (December 9) and Ljubljana (December 9). Flights to Budapest, Beirut, Cairo Int'l, Varna, Kiev Boryspil and Warsaw Chopin will be launched later on as more aircraft arrive. As it currently stands, the first A319 in the Air Serbia fleet will make its debut this winter season on Sunday, October 27, on the morning service to Moscow Sheremetyevo. Selected flights to Copenhagen Kastrup will be served by the new aircraft from late October as well. Throughout the winter season the B737-300s will be phased out. In November, services to Zurich, Thessaloniki, Larnaca, Paris CDG (both daily frequencies), Athens Int'l, Düsseldorf Int'l and Berlin Tegel will move to the A319. The transition will continue in December as Stuttgart Echterdingen, London Heathrow, Rome Fiumicino and Tel Aviv Ben Gurion (which will operate on a daily basis without the current stop in Larnaca) are all upgraded to the A319. A few days before the New Year holidays, flights to and from Milan Malpensa, Stockholm Arlanda, Amsterdam Schiphol, Istanbul Atatürk, Frankfurt Int'l and Brussels National will also transition to the Airbus. The first ex-Yugoslavian city to receive the A319 will be Podgorica in November, with one of three daily flights this winter operating with the new jets. Next in line will be Sarajevo which will be served by an ATR72 in the first half of winter but will be upgraded A319 in March 2014. Athens, Moscow, Paris, Vienna and Zurich will all be served twice daily this winter season.
