Weird place for a commercial airport. Looks like an ex-military field in the in the middle of nowhere. Hour and a half drive or so from Munich, 2 and a half from Zurich. Two hours to Konstanz. Ulm’s the closest at an hour drive but it only has about 130,000 people.
The airport can accommodate two narrow body jets at a time, and has no jetways. It does, however, appear to have massive parking lots.
Ryan Air typically uses smaller airports near major cities. Less crowded and much lower fees. Then they often run a bus into the city.
That is common of airports serviced by Ryan Air. A cheap economy airline that uses old military fields some distances from major cities.
