Get your big coat on! Alaska Airlines begins daily nonstop service between Seattle and London Heathrow today, the carrier’s second European route launch this year and a clear signal that the fourth-largest US airline is committing real capital to long-haul opening up a new frontier for UK flyers to the northern US state.
The Heathrow service follows last month’s Rome launch and precedes a May 28 start to Reykjavík, giving Alaska three European destinations inside roughly two months. The London flights operate from Terminal 3, slotting the carrier into the oneworld bank alongside British Airways, Iberia, Finnair and Qatar Airways, according to the airline.
For trade buyers, the more interesting development sits behind the route map.
Why it matters
Alaska’s Heathrow entry adds a new transatlantic option for travel sellers routing clients between the UK and the US Pacific Northwest, a market that has historically depended on British Airways and Delta-Virgin Atlantic metal. The carrier’s oneworld membership means agents can build itineraries through Heathrow onward to Doha, Madrid and Dublin on partner inventory, with reciprocal status benefits for Sapphire and Emerald members. The cargo capacity on the 787-9 also opens fresh belly-hold options for perishables moving between the UK and the US West Coast, including seafood out of Alaska and Hawaii.
Three Europe routes, one product play
The London flight departs Seattle at 21:40 and lands at Heathrow at 15:05. The return leaves London at 17:00 and arrives back in Seattle at 18:50 the same day, a turn timed to suit point-of-sale demand on both sides.
Reykjavík is the more tactical play. The seasonal daily route is timed for Iceland’s peak summer and, more pointedly, for the August 2026 total solar eclipse, with Keflavík sitting inside one of the better viewing corridors. Alaska’s tie-up with Icelandair gives onward access to more than 35 daily departures from the Icelandic capital and Saga Lounge access for First Class and top-tier Atmos Rewards members.
Chief commercial officer Andrew Harrison framed the expansion as a brand exercise as much as a network one, saying the carrier wants to deliver “warm, thoughtful and elevated” service to European guests unfamiliar with the airline.
Ross Baker, chief customer officer at Heathrow, said the route “further strengthens our transatlantic network, opening up opportunities for travel and trade between the UK and the US West Coast.”
Suites product and a flagship lounge
The European launches are being used to roll out Alaska’s new international business class Suites, the lie-flat product now flying on 787-9 services to Incheon, London and Rome. The cabin features Filson-designed bedding, Salt & Stone amenity kits, multi-course dining and a Salt & Straw dessert service. Seattle-Tokyo will get the Suites treatment this autumn when the 787 returns to that market.
Reykjavík, by contrast, will be operated by 737-8 MAX with a refreshed First and Premium Class offering rather than the Suites product.
Behind the route launches sits a heavier capital commitment. Alaska confirmed it will open a 41,000 sq ft, two-level lounge at Seattle-Tacoma International Airport in late 2027, with around 700 seats, showers, multiple bars and à la carte dining. The upper floor will be reserved for international long-haul Suites guests and Atmos Titanium members. Further lounges are planned for Portland this summer, with San Diego and an expanded Honolulu facility due in early 2028.
Alaska also said it will introduce a premium economy cabin by 2028.
Connectivity is being upgraded in parallel. The carrier said its entire 737-8 MAX fleet is being fitted with Starlink Wi-Fi, complimentary via T-Mobile, with the 787-9 Dreamliner fleet due to be fully equipped by autumn.
Premium economy by 2028, Suites already flying, a flagship lounge under construction and three European routes inside two months. The shape of Alaska’s long-haul ambition is no longer in question.
