Istanbul’s Sabiha Gökçen International Airport (SAW) is set to exceed 50 million passengers in annual capacity following the renovation and integration of Terminal 1, according to Türkiye’s Defense Industries Secretariat.
Speaking during the opening ceremony of the upgraded facilities, Haluk Görgün, head of the secretariat, said the airport plays a central role in Türkiye’s integrated aviation, defense, and advanced technology ecosystem and remains one of the country’s most strategic international gateways.
Sabiha Gökçen currently provides direct connections to 154 destinations across 54 countries, working with 23 airlines. Its route network includes 39 domestic and around 115 international destinations, making it a key hub on Istanbul’s Asian side.
Between January and November, the airport handled more than 245,000 flights and served 44 million passengers, with traffic expected to reach over 48 million by year-end. The continued rise in passenger numbers has accelerated the need for expanded runways, airside facilities, and terminal infrastructure.
To address growing demand, the airport operator HEAŞ and the Defense Industries Secretariat implemented the Terminal 2–Terminal 1 integration project. Terminal 1, originally built in 2000 and used as the airport’s international terminal until 2009, has now been repurposed as a satellite terminal to support Terminal 2 and balance operational capacity.
A 240-metre fully enclosed and air-conditioned bridge now links the two terminals, enabling smoother passenger movement between facilities.
The Terminal 1 redevelopment is being carried out in three phases. The first phase, now operational, includes a remote aircraft waiting lounge with five exit gates capable of serving 10 aircraft simultaneously, along with duty-free outlets, food and beverage options, children’s play areas, and passenger support units.
The second phase, currently under construction, will integrate passenger lounges with baggage claim systems, introduce additional passport control points, and expand transit and transfer corridors. Further expansion works are planned in later stages.
With a total investment of around €70 million, the project is expected to add 5.5 million passengers annually, pushing Sabiha Gökçen’s overall capacity beyond 50 million passengers. Additional future investments are also planned, including Terminal 3, a 13-stop intercity transportation zone, expanded parking facilities, and enhanced metro connectivity.
