Had a short stopover at Belgrade. Security personnel were rude and didn't allow me to be in the transit area though I had my onward ticket to Germany and a valid unused Schengen visa. I was deprived of an opportunity to see the airport. I was escorted from the arrival gate straight to the gate of the next flight. They have free wi-fi which was good. There were many pictures of Novak Djokovic in the gate where I was. This is an airport I will definitely avoid in the future.
