Air Serbia will be adding a number of frequencies this coming winter season, which begins on October 27, in addition to the eighteen new routes which are to be maintained from Belgrade and Niš. The carrier will be introducing additional flights from the Serbian capital to Bucharest, Larnaca, Thessaloniki, Tirana and Venice. As a result, services to both the Albanian and Romanian capitals will be maintained on a daily basis, while flights to Thessaloniki will operate five times per week, to Venice three times per week and to Larnaca twice weekly. The airline will also continue to run its newly launched year-round operations from Belgrade to Barcelona, Cairo, Helsinki, Kiev, Krasnodar, Madrid and Rijeka. It will keep the same summer frequencies for most new routes over the winter as well.

This winter season, Air Serbia will have an additional Airbus A319 aircraft at its disposal, enabling it to maintain services from Niš Airport to eleven cities. As a result, the airline will add the most new routes to its destination network among Europe's flag carriers this winter season, which runs until March 29, 2020. Air Serbia’s new routes to Spain, Helsinki and Krasnodar have proved particularly successful this summer. The Serbian carrier is also putting more business class tickets on sale within its short haul network. It is now offering up to twelve business class seats for sale per flight amid an increase in premium travel.

The airline’s CEO, Duncan Naysmith, previously noted, “We are very happy because we managed to significantly improve the functionality of our network, through careful selection of destinations, and in accordance with our passengers’ desires and the strategic plans for further expansion”. He added, “By expanding the Air Serbia international network, our national airline provides strong support for our economy and drives tourism growth". The company’s Corporate Communications Manager, Nikola Vukmanović, said recently, “It is important to note that we expect to significantly increase our overall passenger numbers this year thanks to these new routes”.
