Istanbul layover guide: what to do with 6, 12 or 24 hours

By Mengistu Alemayehu · Updated November 9, 2026 · 6 minute read

Quick answer: with 6 hours or more on a Turkish Airlines connection, check the free Touristanbul city tour. With 9 hours or more you can see Sultanahmet on your own, as long as you can enter Türkiye visa-free or with an approved e-Visa. The airport is far from the old city, so leave plenty of time to get back.

Istanbul Airport is the most connected airport in the world, according to OAG's Megahubs 2026 ranking, and well over half of its passengers are connecting. That makes it one of the best layover cities on Earth: two continents, Byzantine and Ottoman history, and some of the best food anywhere.

Can you leave the airport?

If you stay in the international transit area, you do not need a visa.
To leave the airport you must be able to enter Türkiye, either visa-free for your nationality or with an approved Turkish e-Visa. Check the rules for your passport before you fly.
Make sure your checked bags are through-checked to your final destination.

Free and good-value layover perks

Touristanbul: Turkish Airlines offers a free guided group city tour with a meal for international-to-international connections of roughly 6 to 24 hours. Places are limited and first come, first served at the Touristanbul / Hotel Desk in the arrivals area.
Free hotel: for much longer Turkish Airlines connections, a free hotel night may be available instead of the tour, subject to fare rules and availability.
Both depend on availability and change from time to time, so confirm with Turkish Airlines before you rely on them.

Getting into the city

The airport is a long way from the historic centre, usually around 45 to 75 minutes by road depending on traffic.
The M11 metro line connects the airport to the city's metro network, and airport buses (HAVAIST) run to central districts.
Taxis are available outside arrivals. Agree the route or use the meter, and allow extra time at rush hour.

The Sultanahmet classic

Hagia Sophia, the Blue Mosque and the Hippodrome are all within walking distance of each other. Add a quick look at the Basilica Cistern if time allows.

After Sultanahmet, explore the Grand Bazaar and Spice Bazaar, eat a fish sandwich at Eminönü, and take a short ferry on the Bosphorus at sunset.
