Diyarbakır Airport — Diyarbakır, Turkey

Diyarbakır Airport, using the code DIY, serves Diyarbakır, the largest city in southeastern Turkey and a historic center along the Tigris River with ancient basalt city walls. The airport functions as both a civilian terminal and a Turkish Air Force base, giving it dual military and commercial significance in a strategically important region near the Syrian and Iraqi borders. DIY handles a steady volume of domestic flights connecting the city to Istanbul, Ankara, and other major Turkish hubs, serving business travel, government functions, and visits to the old city's UNESCO-listed fortifications. Its role as a joint-use airport means passenger operations sometimes coexist with military scheduling considerations distinct from purely civil airports.
