Currently, it is known that Croatia Airlines will operate flights between Dubrovnik and Belgrade, which are expected to commence on June 20. Jat Airways will operate flights between Belgrade and Pula. Croatia Airlines will most likely operate flights between Zagreb and Belgrade with the service codeshared by Jat Airways, although this has not been officially confirmed. Rumours are circulating that the Zagreb – Belgrade service will be brought forward and will start this summer instead of the 2011/2012 winter, as was initially planed. Finally, which airline will fly between Split and Belgrade remains to be seen.
Croatia Airlines has never operated scheduled flights to Belgrade while Jat Airways served flights between Belgrade and Pula in 2008, although both Zagreb and Split haven’t been in the airline’s network for almost 2 decades.
