How long of a layover do I need in Istanbul?
Istanbul airport is one of the biggest airports in the world and it is 50 minutes away from city center. So you will need almost 2 hours for transfers. So for a short visit and check in time, you will need about 6 hours and more. If you have 8 hours and more you may visit some nice points and get some delicious meal in the city and try some traditional local taste.
