Interesting! German Regional airports need much more passengers than Austrian airports to be profitable.
There are some reasons for that because Austrian legislation is more flexible with regards to the utilization of staff but on the other hand Austrian airports have to pay for the security leading to much higher airport fees that should actually reduce traffic and profitability. The business model of Austrian airports seems to work (at least until the breakout of COVID). I took the available annual accounts and adjusted them to show the data without any public support (as far as this was obvious). I took the map from the website of the German Airports Association (ADV), I hope this is o.k.?
