The oneworld Alliance is further expanding its footprint at London Heathrow Airport as Alaska Airlines prepares to launch its new nonstop service between Seattle and London on Friday, 22 May 2026. The new route will increase the alliance's presence at Heathrow to 14 member airlines, strengthening the airport's position as oneworld's most connected global hub.

During the summer schedule, oneworld carriers are expected to operate nearly 2,800 weekly departures from Heathrow, linking passengers directly to more than 160 destinations across over 60 countries. The airport continues to play a major role in the alliance's global network, offering extensive international connectivity and travel options.

Passengers travelling through Heathrow also have access to premium facilities, including 13 First and Business Class lounges across Terminals 3, 4 and 5. These lounges are operated by British Airways, American Airlines, Cathay Pacific, Qantas and Qatar Airways, adding to the overall travel experience for premium flyers.

London continues to be a key stop for global travellers. According to oneworld data, 71 percent of Round the World bookings made this year through oneworld.com include London in their travel plans. The alliance also revealed that nearly 29 million customers travelled from, to or through Heathrow last year, with almost 30 percent connecting between oneworld member airlines.

Ole Orvér, CEO of oneworld, 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."

Speaking on the expansion, Brett Catlin, Vice President of Loyalty, Partnerships and International at Alaska Airlines, said: "As we launch service to London, we're proud to further strengthen the value of our oneworld membership for guests."

"As one of the world's most important international gateways, London opens up even more seamless options for our guests to connect onward across Europe and beyond through the oneworld alliance."

Ross Baker, Heathrow's Chief Customer Officer, added: "At Heathrow, we are proud to be the UK's gateway to the world and the most served global hub for the oneworld alliance."

"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."

At Heathrow, oneworld member airlines operate across different terminals. Terminal 3 hosts Alaska Airlines, American Airlines, British Airways, Cathay Pacific, Finnair, Japan Airlines, Qantas, Royal Jordanian and SriLankan Airlines. Terminal 4 includes Malaysia Airlines, Qatar Airways, Oman Air and Royal Air Maroc, while Terminal 5 serves British Airways and Iberia.

Apart from Heathrow, the alliance's next biggest hubs with 11 member airlines include Dallas/Fort Worth, Doha, Tokyo-Narita and New York's John F. Kennedy airports.
