Airport data: OurAirports (public domain), snapshot 2026-10-28. Only airports with scheduled passenger service and an IATA code.
Every three-letter code here belongs to an airport with scheduled passenger flights. Start with Easy, the world-famous hubs, and work up to Expert, where the codes belong to island strips, seaplane bases and heliports. The Türkiye set covers all 51 scheduled airports in the country, listed by province. After each answer you get the airport's elevation and runways, and a link to its airport profile when we have one.
Map distances are great-circle distances, the shortest path over the Earth's surface. If you know the codes already, test the rest of your aviation knowledge in How Aviation Are You?
