Istanbul Airport has been ranked the world's most connected airport in aviation data firm OAG's "Megahubs 2026" list, published on September 18, 2026, according to a statement by its operator, IGA. The hub moved ahead of London Heathrow to claim the top position for global connectivity.

IGA Chief Executive Selahattin Bilgen told CNN International's "Quest Means Business," speaking live from a London studio, that the result followed the airport's status as Europe's busiest for air traffic and its emergence as the continent's largest cargo centre after overtaking Frankfurt. He credited long-term planning alongside capacity investment, saying, "Leadership in global connectivity came after becoming Europe's busiest airport. These achievements are the direct result of our long-term planning and capacity investments."

Bilgen said a fourth runway that entered service in September would support further growth, and noted that an efficient operating model and more than 110 airlines serving the airport had strengthened its network of connections. He added that the new runway would add capacity and improve efficiency for airline partners.

On Middle East airspace restrictions, Bilgen described the effects of regional developments as two-directional: the airport's connectivity helped it absorb some east-west traffic, while disruptions led to flight cancellations. Istanbul serves as a gateway for many countries in the Middle East and Africa, he said, adding that year-end passenger forecasts had been revised as a result.
