Istanbul Airport has overtaken London Heathrow as Europe's busiest airport. In July, Istanbul handled 8.15 million passengers, surpassing Heathrow by nearly 300,000. Heathrow had dominated European aviation since 1996 with only brief interruptions. This milestone signals a major shift in the continent's aviation landscape.
Heathrow's passenger numbers fell 1.5 percent compared to July last year. Istanbul, in contrast, recorded a 2.3 percent increase over the same period. Heathrow was particularly affected by declining traffic on Middle East routes. Those routes dropped 20.2 percent due to ongoing regional conflicts. The London hub currently operates its two runways at near full capacity.
Turkey's strategic position between Europe and Asia gives Istanbul a competitive advantage. Turkish Airlines expanded its fleet by 14 percent to 552 aircraft by mid-2026. The airline's total revenue grew 20.5 percent to 7.2 billion dollars in the second quarter. Istanbul Airport connects to over 330 destinations across more than 120 countries. This robust connectivity attracts both business and leisure travellers worldwide.
Heathrow has responded by strengthening its case for a third runway. If approved, expansion would raise its capacity to 150 million passengers annually. Istanbul Airport also plans to increase its capacity to 200 million passengers eventually. Both airports are investing heavily to secure their positions in global aviation. The competition between these hubs reflects broader trends in international trade and travel.
