With a 3-hour layover at Istanbul Airport (IST) in 2026, you won't have enough time to leave for the city, but the terminal itself is a world-class destination. Start by exploring the Duty-Free zone, which is one of the largest in the world, featuring a "Bazaar" section where you can sample authentic Turkish Delight and baklava. If you need to relax, the IGA Sleepods offer private cabins for a quick nap, or you can pay for access to the IGA Lounge, which provides showers, a buffet, and quiet zones. For art lovers, the airport hosts the Istanbul Airport Museum and various rotating art galleries showcasing Turkish history. If you are hungry, head to the "Old Bazaar" area for a traditional Turkish coffee or a quick "doner" kebab. Note that the airport is massive—it can take 20 minutes to walk between some gates—so you should spend the first hour orienting yourself and the final hour near your departure gate. The free 1-hour Wi-Fi is available via "Kiosk" codes found throughout the terminal if you need to catch up on work.
