I live in Munich and fly out of Augsburg. It takes me about 35 minutes to get to the Airport in Augsburg and frankly though, I consider such a time frame to commute to a GA Airport fairly normal.
Just like any other airspace jurisdiction, there are rules, regulations and constraints that must be adhered to when flying in Bavaria. It is not that bad though and if you give considerable attention to the circumstances, you will really enjoy flying in Bavaria.
You can use public Transportation (which is very reliable) to get to GA Airports in the Munich area, but you would have to use taxi for the last mile.
It is fun flying in the Munich area and the landings fees aren't to heavy. PM me if you need reliable and credible Information.
