Hévíz–Balaton Airport — Sármellék, Hungary

Hévíz-Balaton Airport, coded SOB, serves the Lake Balaton region in western Hungary, one of Central Europe's most popular freshwater tourist destinations. Located near the towns of Hévíz and Sármellék, the airport primarily handles seasonal charter flights bringing international tourists, especially from Germany and other Western European countries, to enjoy Lake Balaton's beaches, thermal spas, and wine regions. Hévíz itself is famous for its natural thermal lake, drawing wellness tourists year-round, which supplements the airport's summer beach-season traffic. SOB's relatively small scale and seasonal operating pattern reflect its niche role as a leisure-tourism airport rather than a major national aviation hub, catering to Hungary's thriving lake and spa tourism industry.
