VIE airport should be really improved if they are going to be the hub between east and west. Nowadays it isn't as attractive airport as Zurich or Munich for example. The Schengen side is quite OK
, but non-Schengen side is far below good standards. The Non-Schengen side is small, not good facilities at all (few toilets, 2 small cafe/bars) and seems to be quite old. There is only few windows to apron as well.. Also arrival hall (landside) is very dark, small and outdated... just like arriving to some dirty subway station.
In overall, VIE
isn't one of the best airports, but it is quite OK
, especially the Schengen side like I told. If you travelling only from Schengen country to other, then VIE
is good airport for transit.
