Istanbul Airport is about to get even busier — in a good way. On September 18, Türkiye's biggest aviation hub will formally inaugurate its fourth main runway, with President Recep Tayyip Erdoğan expected at the ceremony. Transport and Infrastructure Minister Abdulkadir Uraloğlu confirmed the date, noting the opening was pulled forward from an original end-of-year target.
The airport, which already became the first in Europe to run three independent main runways at the same time, currently operates five runways in total — three main and two backups, all aligned north-south. The new strip changes that geometry: it's the airport's first east-west runway, a concrete stretch 2,820 metres long and 45 metres wide, bringing the total count to six.
Why does orientation matter? Crosswinds. Having a runway on a different axis gives controllers far more flexibility when wind and weather turn awkward, which should mean fewer diversions and delays. Officials also expect shorter taxiing times — particularly useful for domestic flights and routes heading east — plus lower fuel burn, bigger safety margins for takeoffs and landings, and better on-time departure rates.
For anyone connecting through Istanbul, the capacity story is the bigger picture. The hub already links more than 340 destinations through over 110 airlines, and it's the home base of Turkish Airlines, one of the world's most extensive networks. Extra runway capacity should translate into more slots, more frequencies and smoother connections — handy if you're routing between Europe and Asia, Africa or the Middle East via IST, as millions do each year.
There's no immediate action needed from travellers here: you won't board differently or notice much on the ground at first. But if you've been put off by Istanbul's occasional congestion or tight connection windows, the fourth main runway is a quiet promise that things should run a bit more smoothly — and that the airport's already huge route map will keep growing.
