The case for a third runway at Heathrow 'has never been clearer,' the airport said today, after it lost its position as Europe's busiest airport to Istanbul.

Figures published by Heathrow show 7.86million passengers passed through its four terminals last month, a 1.5 per cent fall compared with the same month last year.

The Turkish city recorded 8.15 million passengers over the same period.

Heathrow held the top spot as Europe's busiest airport between 1996 and 2019, before losing the title during the pandemic, and reclaiming it in 2023.

The west London hub said the Iran war weighed on traffic, with passengers on Middle East routes in July down 20.2 per cent year-on-year.
