Several Air Serbia flights that were planned for Thursday afternoon were delayed for two or more hours, due to a lack of Belgrade airport baggage loading staff, as well as an insufficient number of special pushback vehicles, said Serbia's flag carrier Air Serbia.

“Due to the resulting disruptions from the planned flight schedule, further phase delays are possible during the evening and additional impact on the on-time performance of the Serbian national airline,” said the company.

It added that the competent services of Air Serbia are doing everything in their power to maintain operations in line with the planned flight schedule.
