The airport welcomed over eight million travellers in August alone.

Heathrow Airport recorded a record 23.4 million passengers in Q3, welcoming over eight million travellers in August alone – an all-time monthly high. Retail revenue for the nine months ended 30 September 2025 increased +2.8% to reach £588 million (around US$785m).

Total revenue in the first nine months of 2025 rose by +2% to £2,703 million (US$3,606m), a performance Heathrow attributed to strong long-haul flying, an increased uptake of premium services, and a favourable property performance.

The company said these gains partially offset ongoing headwinds, such as the loss of VAT-free shopping. Passenger traffic for the period grew by +0.3% to 63.3 million.

Adjusted EBITDA for the nine months decreased slightly by -0.2% to £1,533 million; adjusted pre-tax profits fell -38% to £217 million.

Heathrow lauds punctuality progress

Heathrow highlighted its positive punctuality track record, having delivered the best on-time performance in Q3 with fewer cancellations, surpassing all European hubs to become Europe’s most punctual airport.

The company also noted that its security checkpoints investment was paying dividends, with over 97% of passengers waiting less than five minutes. So far this year Heathrow has invested £901 million to improve the passenger experience and boost operational resilience.

Key projects include an upgrade to the passenger transit system in T5. A further six new vehicles have been added to the fleet, alongside a new track layout, which will increase capacity while reducing waiting times for passengers.

Nine new routes were launched this summer, with two more to follow this winter. Three new airlines – Riyadh Air, Air Peace, and IndiGo – will also begin operations from the airport.

Heathrow said the performance outlook for 2025 remained consistent with its June 2025 Investor Report. Overall passenger demand is expected to surpass 2024 levels.

Heathrow CFO Sally Ding commented: “This is a great time for Heathrow customers – with more people than ever flying from the airport, we are proud to be Europe’s most punctual hub and the best-connected airport in the world.

Key investment projects in 2025 include an upgrade to the T5 passenger transit system, reducing passenger wait times.

“We already invest over £1bn every year to improve the airport and we have exciting plans to increase that investment to deliver the modern, upgraded facilities customers want.”

She concluded: “We are also working to unlock a third runway which can be operational within a decade, giving customers more value and choice and securing economic growth across the whole country for decades to come. Ministers now need to move forward to unlock this 100% privately financed investment and get Britain growing.”
