Air Serbia should finally replace old ATR-72s
Pros: First of all, I like the fact that I am able to arrive to Vienna fast, where I travel often.
It is also cheaper than Austrian Airlines, and quality-for-money is much better.
Cons: Ground crew was almost rude. Boarding was fast, but a bit unorganized.
They should definitely replace old school ATR-72s with newer short-haul aircraft.
