Heathrow rounded off a super summer by welcoming 7.5 million passengers in August.
The total is 2% up on the corresponding period a year ago, making it the second busiest month in the airport’s history.
Heathrow CEO, John Holland-Kaye, says: “Demand to travel from Heathrow has never been stronger. Every day we’re welcoming record numbers of passengers to Heathrow with modern British hospitality and our trade with the rest of the world is growing in the double-digits.
"Heathrow is firing on all cylinders and showing the world our country is open for business.”
UK destinations saw 6% passenger growth on the back of recently launched Flybe flights to Scotland.
Middle Eastern destinations were also popular with travellers with fuller aircraft leading to a 7% increase in passengers to the region.
Cargo flowing through the UK’s largest port climbed 13% to 139,000 tonnes making August the 13th consecutive record month for cargo volumes at LHR.
Latin America was the fastest growing trading market with cargo volumes increasing 30% in August.
According to the gateway, North America also performed well with volumes up 13% to nearly 50,000 tonnes as American Airlines, United and Air Canada increased cargo.
Strong growth to China, Hong Kong and Singapore also helped East Asia record a 12% cargo uplift.
The airport notes that "next-generation aircraft are making Heathrow cleaner and quieter" with more than 700 additional flights on B787s this August versus last year.
B787s are the fastest growing aircraft type at the UK’s hub.
• Edinburgh (+8.3%); Glasgow (+7%); London Gatwick (+2.1%); London Luton (+6.8%); London Stansted (+9.9%); and Manchester (+8%) have all reported healthy increases in passenger traffic this August.
Gatwick Airport CEO, Stewart Wingate, notes: “Gatwick has just had its biggest-ever month during its busiest-ever summer holiday period – this clearly demonstrates the passenger demand for the growing global connectivity offered by Gatwick.
"Later this year, we’ll be further adding to our more than 60 long-haul connections with routes to Denver, Seattle, Austin, Chicago, Taipei and Singapore starting.
“As well, we continue to focus on delivering the best passenger experience at the airport with Jamie Oliver opening his new Diner in the South Terminal and an expanded World Duty Free store also arriving in the North.
“Service has been at the forefront of our summer. We have worked closely with our airlines and ground handlers to help ensure that more planes depart on time and I am pleased with the improvement we’ve made during our busiest ever summer.
“As Gatwick continues to grow beyond 45 million annual passengers, we remain ready and willing to build our financeable and deliverable second runway scheme instead of, or in addition to, Heathrow should the Government give us the green light.”
