Heathrow reports July traffic near 7.86 million, down 1.5% from last year, while Istanbul remains Europe’s busiest hub. The airport argues expansion is essential to restore UK leadership and support growth after a summer peak, with new routes from ITA Airways, Alaska Airlines and Riyadh Air highlighting demand.

Heathrow remains under pressure to expand as Istanbul overtakes it in Europe, while Dubai declines.
