Alaska Airlines launches new nonstop Seattle-to-London flight starting in 2026

Alaska Airlines announced its newest nonstop flight out of Seattle: a straight shot to London.

Starting in May 2026, the nonstop flight will travel from the Seattle-Tacoma International Airport (SEA) to Heathrow Airport, the largest international airport in the United Kingdom. The airport resides in Hounslow, located an hour outside of London.

The daily service will operate on Alaska Airlines’ 787 Dreamliner.

London is Alaska Airlines’ fifth intercontinental destination, alongside Rome, Reykjavik, Tokyo, and Seoul. According to the airline, the new route strengthens business ties, with London being the largest corporate market from Seattle.

“By 2030, we plan to serve at least 12 intercontinental destinations from Seattle, with additional routes to be announced in the years to come,” Alaska Airlines stated. “We currently have four Boeing 787-9s in our fleet, with a fifth aircraft recently delivered.”

Guests traveling from the U.S. can now purchase airfares to London for as low as $699 round-trip at alaskaair.com.

Alaska Airlines hit hard by federal shutdown

According to aviation analysts, the federal shutdown cost Alaska Airlines millions of dollars. The airline’s fourth-quarter income is expected to fall by $32 million.

The company told investors it lost 15 cents per share. Flight cancellations at SEA and other airports lasted 43 days.

According to The Puget Sound Business Journal, Delta reports a $200 million hit. United, JetBlue, and Southwest could see losses, too.
