Istanbul Airport, the largest airport in Turkey on October 29, 2018 was opened to commercial flights. However, because it was built very quickly, the construction of the subway did not reach the opening even though it was planned. Currently, there is no train or metro line from Istanbul airport to the city center. On the other hand, the construction of a subway continues. When the M11 Gayrettepe - Istanbul airport metro line is completed, it will connect Istanbul airport to the city center. It is too bad that there is no train from the biggest airport of Istanbul, one of the world's largest cities, to the city center; transportation is provided by road and if you come to rush hour, you may be stuck for hours in traffic while trying to reach your destination. Therefore, by public transport, you can choose to travel by taxi rather than by bus. You can reach all information about the taxi ride to the city at Istanbul Airport from 'Taxi Transfer From Istanbul Airport' article.
