Stuttgart Airport — Stuttgart, Germany

Set on a plateau above the Neckar valley, STR serves the automotive heartland of Baden-Wurttemberg, a region anchored by the headquarters of Mercedes-Benz and Porsche, both tied closely to the city's industrial identity. Pilots have long noted the airport's demanding terrain, since hills and shifting winds around the Filder plain can complicate landings compared with flatter German airports. A single main runway handles traffic that mixes business travelers linked to the region's engineering and manufacturing firms with leisure passengers connecting toward Mediterranean destinations. The nearby Stuttgart trade fair grounds, Messe Stuttgart, generate additional demand during major industrial exhibitions throughout the year. Rail and light-rail connections link the terminal directly to Stuttgart's main station, folding the airport into the wider regional transport network. Despite being smaller than Frankfurt or Munich, it remains an important gateway for one of Germany's most industrially productive states.
