Munich Airport (MUC) sits around 40 kilometres northeast of the centre, roughly 45 minutes by S-Bahn, and carries the great majority of scheduled traffic. Memmingen Airport (FMM), marketed by some low-cost carriers as “Munich West,” is in fact closer to 120 kilometres away and needs a shuttle bus of an hour and a half or more each way. Which of the two a booking actually arrives at is worth confirming before the rest of the stay is planned.
Munich carries a genuine dual identity: a compact, walkable Bavarian capital that can be crossed on foot in well under an hour, and a base camp for the Alps, lakes and countryside beyond it that asks for a car, a driver or an organised day trip. A stay that names which of these two trips it mostly is tends to choose its district, and its pace, more coherently.
