Reflecting its potential as steady growth, Istanbul Sabiha Gökçen Airport (ISG) was the fastest growing airport among “MAJOR Airports” in Europe with over 40 million passengers, according to the Airports Council International (ACI) May 2025 Traffic Report.

ISG recorded a 14.9% growth compared to the same period last year, serving approximately 3.94 million passengers in May.

Istanbul Sabiha Gökçen Airport ranks 9th among European airports in terms of passenger numbers since the beginning of 2025.

Sabiha Gökçen Airport, which has become a strategic hub for air connections between Europe, Asia, and Africa, is making the most of its limited capacity thanks to the “Passenger Flow Improvement Projects” implemented since 2024 to meet the dynamically increasing passenger demand. 

Infrastructure and service renewal works at the terminal will continue in 2025 without disrupting current passenger traffic, while technological and operational improvements in security and passport processes will create comfort zones for passengers during the busy holiday season.

According to data from HEAŞ, the Sabiha Gökçen International Airport Authority, a subsidiary of the Defense Industries Presidency, passenger traffic in May 2025 reached approximately 3,949,000, with 1,775,000 passengers on domestic routes and 2,174,000 on international routes. 

Known as “The City's Airport” due to its transportation conveniences and proximity to central locations, Istanbul Sabiha Gökçen International Airport (ISG) connects Istanbul and its surroundings to a total of 148 destinations in 53 countries, including 39 domestic and 109 international routes, thanks to its newly developed partnerships.
