Is 90 minutes enough for a connecting flight in Istanbul?

Allow at least 1.5 hours for your transit. This will give you enough time to go through all of the necessary procedures and get to your boarding gate. If you have a long transit, you can take advantage of the many amenities and services offered at the airport, such as restaurants, shops, lounges, and sleeping capsules.



A 90-minute layover at Istanbul Airport (IST) in 2026 is considered a "legal connection," but it is arguably the absolute high-fidelity minimum required for a stress-free transit. IST is one of the largest and most high-fidelity airport terminals in the world, and walking from one concourse to another can easily take 20 to 30 minutes of brisk movement. If your incoming flight is delayed even by 15 minutes, or if you must pass through a high-fidelity security re-screening or document check, the window becomes dangerously tight. For 2026 travelers, a 90-minute window is usually sufficient if both flights are on a single ticket with Turkish Airlines, as they provide high-fidelity "Short Connection" support. However, if you are "Self-Connecting" or have checked bags on separate tickets, 90 minutes is a high-fidelity impossibility because you must clear immigration, collect bags, and re-check them. For a high-value and reliable transit, experts recommend a high-fidelity buffer of at least 2.5 to 3 hours to account for the massive scale of the terminal and the high volume of international passengers moving through this global hub.
