Located on the European side of Turkey’s most popular city, Istanbul Airport makes almost every other transit hub seem like a shack. Not only does it have a full-fledged mall filled with duty-free designer stores and souvenir shops, but it also has showers, a hotel inside the terminal and even a museum.
Plus, if you’re flying Turkish Airlines, you’ll be happy to have a long layover at this airport. The impressive stopover program lets you do a free (yes, completely free) tour of the city that includes transportation, meals, guides and entrances to landmarks like the Hagia Sophia and Dolmabahce Palace. Staying overnight? Eligible flyers could also get a free night at a nearby hotel.
