With the arrival of direct flights from Seattle with Alaska Airlines, London Heathrow has further cemented its status as the airport most-served by oneworld Alliance members.
Alaska’s arrival brings the total number of oneworld airlines operating out of Heathrow to 14. The alliance says 29 million of their customers flew to, or through, the airport in 2025, 30% of these connecting between oneworld carriers. Additionally, Heathrow was featured in 71% of Round the World itineraries.
Ole Orvér, oneworld’s CEO, said:
With service from the most oneworld carriers and nearly 400 daily departures, London Heathrow is a cornerstone of our global network, where our members work together to deliver smooth connectivity for millions of customers every year. It is also one of the world’s leading business travel markets, with more than 160,000 premium seats offered weekly by our airlines, and we are delighted to welcome Alaska Airlines as it launches its inaugural Seattle service from Heathrow, further expanding travel choices for oneworld customers.
oneworld’s next most-served hubs include Dallas Fort Worth, Tokyo Narita, and New York JFK, each hosting 11 member airlines.
With the launch of Alaska Air Group flights to Seattle, Fiji Airways becomes the only carrier in the alliance not to have a presence at Heathrow. The airline joined oneworld in March 2025, significantly expanding the alliance’s presence in the South Pacific.
Ross Baker, Heathrow’s Chief Customer Officer, said:
At Heathrow, we are proud to be the UK’s gateway to the world and the most served global hub for the oneworld alliance. Our strong partnership gives passengers more choice, easier connections and a smoother journey every step of the way. The arrival of Alaska Airlines’ new Seattle service brings even more option for travellers, whether they’re visiting friends and family or travelling for business. With millions of oneworld customers choosing Heathrow each year, we’re continuing to work together to make every journey better.
