We recommend at least 1 hour 15 min for a comfortable connection at Ataturk. The minimum connection time is 45 minutes for domestic flights and 75 minutes for international flights. Transit between terminals takes up to 35 minutes.

Domestic-to-Domestic: 45 min. Domestic-to-International: 60 min. International-to-Domestic: 60 min. International-to-International: 75 min. These are the shortest layovers airlines will sell at Ataturk.

Istanbul Airport (which now carries the historic 'IST' code after Atatürk Airport closed to commercial traffic in 2019) is a sprawling single-terminal mega-hub built for Turkish Airlines' global network. Connections are straightforward in concept — one continuous terminal building — but the sheer scale means long walks and, for some itineraries, mandatory security re-screening or passport control that can eat up your buffer. Off-peak it's very manageable; during the airline's overnight banks it gets crowded and queues lengthen fast. Most transfers are done on foot via extensive moving walkways within the single terminal building, but the farthest F-gate piers require the internal automated people mover (APM) train, adding real time versus a straight walk. Passengers connecting from domestic to international (or vice versa) must pass through passport control and often a second security screening, while remote-stand arrivals may need an extra shuttle bus ride before even entering the terminal.

Still under any published MCT; the walk alone to a far pier can exceed this. See full 30 min guide →
