Heathrow Airport recorded its busiest September on record, welcoming nearly 7.4 million passengers and capping off a record-breaking summer season. The figures reaffirm Heathrow’s position as the UK’s primary hub for international travel and one of Europe’s most efficient airports.
Despite disruption from a Collins Aerospace IT outage that affected airline systems across Europe, Heathrow’s operations remained resilient, with no flight cancellations. The airport also retained its title as Europe’s most punctual hub and was named the world’s most connected airport for the third consecutive year.
Security performance remained strong, with 95% of passengers clearing security in under five minutes, reflecting Heathrow’s focus on efficiency and customer service.
As the UK’s largest port by value, Heathrow facilitated over £215 billion in trade last year. The airport’s £1.3 billion investment plan for the coming year will continue enhancing service, resilience, and growth opportunities for airlines and UK businesses.
Heathrow also unveiled plans for a 100% privately financed upgrade of a key M25 motorway section, shifting the new stretch 130 metres west to reduce disruption and improve long-term road resilience — part of its third runway development programme.
Heathrow CEO Thomas Woldbye said:
“Operating Europe’s largest airport doesn’t come without challenges, but I’m proud our team delivered under pressure — maintaining strong punctuality and security while welcoming nearly 7.4 million passengers in September. Heathrow remains vital to the UK’s economic growth, and we’ll continue investing to create even more opportunities for passengers, airlines, and the country.”
