Heathrow Airport is no longer Europe’s busiest airport after Istanbul Airport overtook it in July 2026. Heathrow handled 7.86 million passengers last month, while Istanbul recorded 8.15 million, according to figures released by Airports Council International and reported by the BBC.
The decline in Heathrow’s passenger numbers was partly attributed to a 20.2% year-on-year drop in Middle East routes. Heathrow said the US-Israel conflict with Iran had affected travel demand in the region. The airport had previously held the title of Europe’s busiest from 1996 to 2019, regained it in 2023, and retained it until 2025.

Capacity constraints and expansion plans
Heathrow’s two runways are operating at near-full capacity, limiting its ability to grow passenger numbers. The airport’s owners have long argued for a third runway, which would allow it to handle up to 150 million passengers annually. Heathrow said the case for expansion had never been clearer and that the project would deliver economic growth.
In a statement, Heathrow said, "Our plans will ensure the country gets the infrastructure it needs to stay competitive and will deliver all-important economic growth." The airport recorded 84.46 million passengers in 2025, with 19 July 2026 marking its busiest day so far this year, handling 267,000 passengers.

Heathrow also noted that several new airlines began serving the airport in July 2026, which it said demonstrated clear demand for access. Last month, the Civil Aviation Authority allowed Heathrow to increase charges to airlines to recover costs spent on early stages of the third runway project.
What happens next
Heathrow’s expansion plans remain subject to government approval. The airport’s owners have not provided a timeline for when a decision might be made. If approved, construction of the third runway would take several years to complete. Residents and campaign groups opposed to the expansion have previously indicated they will challenge any approval in court.
