Heathrow beats September records

Heathrow welcomed nearly 7.4 million passengers last month, making it the busiest September ever for the airport and rounding off a record-breaking summer.

Even with the unexpected Collins Aerospace IT issue that impacted airline systems across Europe, Heathrow teams ensured passengers got away without cancellations.

Heathrow remained Europe’s most punctual hub and reached a major milestone in global connectivity, being named the most connected airport in the world for the third consecutive year. Security performance also remained consistent, with 95% of passengers waiting less than five minutes in security.

As the UK’s largest port by value, Heathrow helped drive over £215 billion in trade last year, connecting businesses to global markets and reinforcing its position as one of the country’s biggest economic contributors. Its £1.3 billion investment plan for the coming year is set to improve service, operational resilience and growth for both airlines and UK businesses.

Heathrow has also announced plans for a 100% privately financed, wider and safer stretch of motorway at one of the busiest junctions on the M25 as part of its third runway development. The new section will be built ‘offline’, 130 metres to the west, minimising disruption for motorists and improving long-term infrastructure resilience.

Heathrow CEO Thomas Woldbye said: “This summer at Heathrow was one to be celebrated. Operating Europe’s largest airport doesn’t come without its challenges but I’m proud that our team delivered under pressure — welcoming nearly 7.4 million passengers in September alone while maintaining strong performance in punctuality and security. 

"We continued to lead the pack in global connectivity, all while keeping the passenger experience smooth for millions. It’s a clear sign that Heathrow is vital to the UK’s economic growth and why we will continue to invest in our airport – opening up even more opportunities for passengers, airlines and the country.”
