London - Britain
Istanbul Airport topped the list of the world's most internationally connected airports in the "Mega Hubs 2026" report issued on September 16, 2026 by the OAG organization specializing in travel and aviation data, after rising from second place in 2025 to first place in the world this year. The airport recorded a connectivity index of 265.4 points, with 89,456 potential connections and 337 international destinations, while Turkish Airlines accounts for about 80% of the airport’s capacity.

Heathrow is second and Amsterdam is third

London Heathrow Airport came in second place, after potential connections declined by about 6% compared to last year, while Amsterdam Schiphol Airport maintained third place. Kuala Lumpur came fourth and Chicago O'Hare fifth, at a time when the results showed a remarkable improvement for a number of Asian airports, especially in China.

Dubai leads the Middle East and Africa
Regionally, Dubai International Airport maintained its position as the most connected airport in the Middle East and Africa, ranking 31st globally. Johannesburg came second in the region, then King Khalid International Airport in Riyadh ranked 43rd globally, Doha ranked 46th, and Addis Ababa ranked 50th. Cairo also ranked 69th, Abu Dhabi 73rd, Jeddah 78th, and Sharjah 111th.

Unrest is redrawing the map

John Grant, chief analyst at OAG, pointed out that geopolitical factors, closures of some airspace, and changing demand increasingly affected airline networks during the year. This is clearly visible in the Middle East, where the scheduled capacity in August 2026 was about 5.7% lower compared to August 2025, which was reflected in the ranking of airports such as Dubai and Doha.

What does the classification mean for the Arab traveler?
For the Arab traveler, the classification does not only reflect the size of the airport or the number of passengers, but rather measures the ease of traveling through it to the largest possible number of destinations at a suitable time. Dubai's regional leadership and the rise of Riyadh confirm the continued Gulf competition for the role of the "global hub," while Istanbul stands out as one of the strongest options for linking Europe, Asia, and the Middle East.

The OAG ranking is based on the number of possible connections compared to the number of destinations, based on the busiest global aviation day of the year, which is August 2, 2026.
