Growth and development In 1911, a small apron with two hangars was built in Yeşilköy, Istanbul, for the Ottoman Armed Forces.
Mustafa Kemal Atatürk founded Türk Tayyare Cemiyeti (Turkish Aircraft Company, today
Türk Hava Kurumu - THK) in 1925. In 1933, today's
Turkish Airlines, the Türkiye Devlet Hava Yolları started its flights with two
Curtiss Kingbird aircraft. Flights from Istanbul to Ankara and Athens began. The small apron was expanded and a new passenger terminal was built. This is considered the beginning of the airport's 86-year history. It was originally named
Yeşilköy Airport. In the 1980s, it was renamed
Atatürk International Airport. It served more than 60 million passengers in 2015, making it the
11th-busiest airport in the world in terms of total passenger traffic and the
10th-busiest in the world in terms of international passenger traffic. In 2017, it was
Europe's
5th-busiest airport after
London–Heathrow,
Paris–Charles de Gaulle,
Frankfurt Airport, and
Amsterdam Airport Schiphol, having fallen from third place after a decline in passengers due to security fears.
Closure Istanbul Atatürk Airport was replaced in regards to commercial passenger functions by the newly constructed
Istanbul Airport, in April 2019, in order to meet Istanbul's growing
domestic and international air traffic demand as a source, destination, and transit point. Both airports were used in parallel for five months from late 2018, with the new airport gradually expanding to serve more domestic and regional destinations. On 6 April 2019, Atatürk's
IST IATA airport code was inherited by Istanbul Airport and Atatürk Airport was assigned the code
ISL after the full transfer of all scheduled passenger activities to the new airport was completed. The final commercial flight, Turkish Airlines Flight 54, left Atatürk Airport on 6 April 2019 at 02:44 for
Singapore. On 5 February 2022,
Turkish Cargo relocated all cargo flights and operations from their former hub at the airport to the new
Istanbul Airport.
Atatürk Airport National Garden Turkey's government announced its plans to construct a giant park on the grounds of the former Istanbul Atatürk Airport (whose operations were transferred to the new Istanbul Airport) in 2019. The park,
Atatürk Airport National Garden, is part of a larger urban transformation plan that seeks to correct some of the haphazard urban planning that characterised most major Turkish cities since the 1970s. Due to the little space available to construct or expand green spaces, new parks are often constructed on spots formerly occupied by factories or other major facilities. The Atatürk Airport National Garden was to be constructed on and around one of the two runways of Atatürk Airport. These runways were already rendered unusable after they were chosen as the site for Istanbul's pandemic hospital in early 2020. More than 132,500 trees are to be planted in place of the asphalt runway and taxiways that will also help to keep the city cooler. Construction commenced in 2022. First areas of the park were opened to the public in 2023. In 2024, the
Council of State cancelled the construction
tender, following a lawsuit filed by
Istanbul Metropolitan Municipality. The park officially opened to the public on 1 November 2025. ==Facilities==
