Turkey spans Europe and Asia, with Istanbul straddling the Bosphorus.

Turkish Airlines' hub at IST connects to 340+ destinations, making Istanbul a natural stopover on routes between Europe, Africa, the Middle East, and Central Asia.

The new airport sits 35km from central Istanbul on the European side, slightly inland and exposed to Black Sea weather systems. Winters (December–March) are cold (0–8°C) with fog, rain, and occasional snow. Snow on the exposed plateau is more likely than in the city. Ice on taxiways causes delays.

Summers are warm (25–32°C) with dry, reliable weather. Spring and fall bring heavy rain and strong northerly winds (Poyraz) that can affect smaller aircraft. Fog is the primary low-season disruption risk. The airport's elevated position makes it slightly windier than the Atatürk site it replaced.
