Buses and taxi services connect Istanbul International Airport to the city center, costing you between QR 3.28-18.93 with a duration of 50-100min depending on the traffic levels; however, there is also a metro line and car hires available. Just outside every airport level there are airport taxi ranks, and depending on the time of travel, taxi fares vary but average QR 155.75. From the airport, two bus shuttles operate every 30-45 minutes, directly to and from the city center at a low cost of QR 12. The metro line in Istanbul is still in operation; from the airport, take the M11 to Gayrettepe, with an expected train swap to M2 taking you to Vezneciler Station, which is within walking distance to Sultanahmet Square, the city center. Renting a car is also an option available for more convenient and independent travel around the city and to the city center.
