Sinop Airport — Sinop, Turkey

NOP identifies Sinop Airport, serving Sinop on Turkey's Black Sea coast. Sinop is a historic port city, once home to ancient Greek settlements and later a notable Ottoman naval base, and NOP provides air access to a region otherwise reliant on coastal roads winding through the Black Sea mountains. The airport primarily handles domestic flights connecting Sinop to Istanbul and Ankara, supporting both tourism to the city's beaches and historic sites and the local economy. NOP is relatively small in scale, reflecting Sinop's status as a mid-sized provincial capital rather than a major travel hub, but it remains an important convenience for a region that is otherwise a long overland drive from Turkey's larger cities.
