Turkey's Atlasglobal will strengthen its operations between Istanbul's Ataturk Airport and Belgrade starting next month. The carrier, which commenced operations to the Serbian capital in March, will introduce an additional three weekly flights for a total of ten per week from June 19, each Monday, Friday and Sunday. Services will operate with the 204-seat Airbus A321 aircraft. The flights are codeshared by Air Serbia, which suspended its own operations to Istanbul in mid-March. In addition to Atlasglobal, Turkish Airlines runs a double daily service from Ataturk to Belgrade, while Pegasus Airlines operates four weekly flights from Sabiha Gokcen Airport to the Serbian capital.
