There is no an offical statement of the company. Since Feb 24, AirSerbia has doubled the number of flights to the Russian capital.  AirSerbia will go back to one flight a day to Moscow, according to the Serbian president. Serbia's airline is the only European company that has kept on flying to Russia since the international flight ban. Air Serbia will stop operating flights from Belgrade to the Russian cities of Kazan and Sochi from the end of January. The last Air Serbia flights to these cities are scheduled for January 18 and 20. However, the company still maintains its flights to the largest cities in the Russian Federation: Moscow and St. Petersburg.
