I am disabled and I had the utter misfortune of having to go to this airport. Seriously, it's like they have never seen a disabled person before. The staff seemed to be annoyed that they had to make allowances for my disability (that I had already called ahead about but nobody did anything.) The toilets were a joke, they were old, unhygienic and broken. The staff were so arrogant, completely unhelpful and I think they were making fun of me. I've been to a few places but I haven't felt so humiliated by airport staff as I have at Nikola Tesla Airport, Belgrade.
