Alaska Airlines has announced plans to enter the transatlantic market in 2026, launching direct flights from Seattle-Tacoma International Airport to London Heathrow and Reykjavik Keflavik. This move marks the airline's first scheduled routes across the Atlantic.
The Seattle-London route is already a competitive corridor. According to aviation analytics company Cirium, it is currently served by Delta Air Lines and Virgin Atlantic—both using Airbus A330-900 aircraft—and British Airways, which operates twice daily with Boeing 777-300ER and various Boeing 787 models. Alaska Airlines commented on its strategy for this route:
"The route offers an alternative to those seeking more flight times, greater premium seat capacity, and the ability to earn and redeem valuable miles on Alaska's award-winning loyalty program. Alaska's expansion into the London market, facilitated by strengthened collaborations with American Airlines and British Airways, presents significant opportunities. These alliances are expected to deepen over time, offering even greater value and connectivity to consumers."
