It took over operations of the airport on 1st May, 2008 and the new International terminal commenced commercial operations on 31st October 2009, a full year ahead of schedule, delivering the promise made to the Hon’ble Prime Minister of Turkey during the ground breaking ceremony on 3rd May 2008.

ISGIA has four fuel tanks and a tri-generation (power, heating and cooling) facility with an installed capacity of 4.14 MW. Airport's cargo terminal area is approximately 7,700 m2 having an apron area of over 63,000 m2.

The consortium invested 470 million Euros in ISGIA including the construction cost of 360 million Euros for the new International terminal.

The project has synergized the strengths and expertise of three consortium partners coming from diverse backgrounds and nationalities.

The general aviation terminal services privately owned aircraft and air taxis. Passenger traffic at the ISGIA has grown by about 31% per annum since 2009.

Air connectivity

As of December 31, 2012, 58 airlines (including 28 scheduled airline operators) operated flights out of ISGIA, serving 90 International and 33 domestic destinations.

Future Potential

Currently, ISGIA has adequate capacity to handle 25 to 28 million passengers annually. With the planned construction of second runway to be readied by end 2015/early 2016, the airside capacity would increase to over 50 million passengers per annum. The runway construction will be fully funded by the Government.

City Connectivity

ISGIA is located approximately 35 km southeast of central Istanbul, on the Asian side of the city, serving a catchment area (within two and a half hour driving radius from the airport) of population in excess of 20 million.

ISGIA has excellent road connectivity to major neighboring cities. A number of rail projects are under various stages of execution, which when completed are expected to further improve connectivity to the airport. The Marmaray Project is a major transportation infrastructure project of approximately 76 km of commuter rail tunnel from Halkali to Gebze, which is expected to be thrown open to public by October 2013. Two more underground rail projects now under various stages of planning and construction, are also expected to improve the connectivity to ISGIA by the end 2014 / early 2015.
