Alaska Airlines has operated its first nonstop service from Seattle-Tacoma International Airport to London Heathrow, inaugurating the carrier’s new transatlantic route between the Pacific Northwest and the UK capital. The flight is part of a newly announced daily, year-round schedule linking Seattle and Heathrow on Alaska’s Boeing 787 Dreamliner fleet, according to the airline.
The westbound service from London to Seattle is due to begin on May 22, 2026, with departures from Heathrow at 5:00 p.m. and scheduled arrival at Seattle at 6:50 p.m. local time. Eastbound, flights leave Seattle at 9:40 p.m. and arrive at Heathrow at 3:05 p.m. the following day.
Heathrow becomes Alaska’s fifth intercontinental destination from Seattle, following the launch of flights to Rome earlier in 2026 that marked the airline’s entry into the transatlantic market. Fares published on Alaska’s website and online travel agencies show one-way saver tickets on the Seattle–London route starting in the $300–$600 range, depending on travel dates.
The new service adds another nonstop option between Seattle and London and provides Alaska passengers with a direct link into one of Europe’s largest hubs, expanding long-haul connectivity from the airline’s primary West Coast gateway.
