Austrian airports, like Wien (Vienna) Schwechat (VIE/LOWW), Innsbruck Kranebitten (INN/LOWI), Salzburg (SZG/LOWS)… would be a great addition to IF. :)
Combine it with the Switserland region
Austrian Region employed combine with Switzerland Region, how European Cup 2008 in Auustria and Switzerland. :-) 🇦🇹✈️🇨🇭
I would already throw a party if they added the LOWL, LOWS, LOWI triangle. Or LOWW, LOWS, LOWL. So many great airports!
