Austrian, Turkish and Air Serbia grounded until May
Press releases from mentioned companies, Austrian, Turkish and Air Serbia, said that companies will keep grounded their aircraft's and suspend all routes until the start of May.
Austrian Airlines was supposed to start with regular flights in April, but because of the coronavirus situation, the company decided to prolong the start date from April 19th to May 03rd, with the possibility of further suspensions. In the summer timetable, Austrian flies daily to Split (A319/320/321 aircraft's) and Dubrovnik (A319/320/321 aircraft's), few rotations daily to Zagreb (Dash/E190 aircraft's), and the plan was to start daily service to Zadar (A320 aircraft's) from this summer season. All flights to Croatian destinations are from Vienna. There is a question of what will happen with those seasonal routes at the moment when Austrian finally take off again, there is a high possibility that only the route VIE-ZAG-VIE will be active, instead of few times daily - few times weekly.. Turkish Airlines actually at the same time postponed the start of its routes until the start of May as well. The company operates reduced domestic flights at this moment. About destinations in Croatia, TK flies twice daily to Zagreb in the summer timetable, and the second destination is Dubrovnik, which is reduced earlier this year from 14 to 11 weekly flights. All Turkish Airlines aircraft's are grounded until 01.05.2020. Air Serbia also postponed their service resumption to May 1st (initially planned for April 13th). Serbian national airline flies to many destinations in Croatia, however, only the route between Belgrade and Zagreb is operating through the whole year. Other routes to Croatia (Pula, Rijeka, Zadar, Split and Dubrovnik) are seasonal.
