Bavarian Swabia is in the western part of Bavaria and its borders coincide with the administrative region (Regierungsbezirk), of which there are seven.
Bavarian Swabia is a part of the much larger Schwaben cultural region which extends across borders into the eastern part of the neighbouring Land of Baden-Württemberg, the northern fringe of Switzerland, the Vorarlberg of Austria and Liechtenstein.
Memmingen Airport (IATA: FMM), is a small airport about 4 km from the centre of Memmingen. It is mostly used by no-frills carriers who market it deceptively as being closer to Munich than it actually is.
Augsburg and Neu-Ulm (just across the border from Ulm) are both well connected by train with frequent departures for Munich, Stuttgart and Nürnberg as well as some high speed trains to places as far away as Paris or Vienna. As part of the greater "Stuttgart 21" project, the line connecting Stuttgart and Ulm is being upgraded, but there is no completion date in sight.
You can take the car to Swabia, but why should you? Gasoline is expensive and (almost) everything is well reachable by public transit. Should you nonetheless decide to take the car the A7 and A8 connect to Neu-Ulm and Augsburg respectively.
Most of the cities like Augsburg and Kempten have decent bus connections between them and with nearby suburbs. However, a lot of smaller settlmeents tend to only have a few buses per day, and on weekends those may be non-existent.
