Dalaman International Airport — Dalaman, Turkey

Turquoise water and pine-covered hillsides define the stretch of Turkish coastline that DLM exists primarily to serve, funneling millions of European sun-seekers each year toward resort towns including Marmaris, Fethiye, and the famously photogenic lagoon at Oludeniz. Charter airlines from the United Kingdom, Germany, and elsewhere in Europe dominate the summer schedule, creating an intensely seasonal pattern that swells passenger counts dramatically between May and October before tapering off through quieter winter months. Dalaman itself is a modest town, with the airport's importance deriving almost entirely from the tourism economy of the surrounding Mugla province rather than any significant local population. Ancient ruins scattered throughout the region, including sites tied to Lycian civilization, add historical depth to what remains primarily a beach and coastal tourism gateway.
