Airports
Istanbul has two international airports: The larger one is the Atatürk International Airport located in the Yeilköy district on the European side, about 24 kilometres (15 mi) west from the city centre. When it was first built, the airport was situated at the western edge of the metropolitan area but now lies within the city bounds. The smaller one is the Sabiha Gökçen International Airport located in the Kurtköy district on the Asian side, close to the Istanbul Park GP Racing Circuit. It is situated approximately 20 kilometres (12 mi) east of the Asian side and 45 kilometres (28 mi) east of the European city centre.
Atatürk International Airport on the European side is the main airport of the city and one of the largest international hubs in the region.
