TL;DR: Alaska Airlines launched daily cargo and passenger service between Seattle and London Heathrow on 21 May 2026, opening a transatlantic trade lane connecting UK shippers to over 100 destinations across the Pacific, Asia and West Coast. The route follows Seattle-Rome service launched in April. Alaska plans at least a dozen long-haul international routes from Seattle by 2030 as it scales its European network.

Alaska Airlines began daily nonstop cargo and passenger service between Seattle and London Heathrow on 21 May 2026, marking the carrier’s second European route. The new transatlantic link connects UK exporters and importers to Alaska’s Pacific hub, opening direct access to Japan, South Korea, Hawaii and over 100 North American destinations.

The Seattle-London service operates year-round from Terminal 3 at Heathrow using Boeing 787-9 Dreamliners configured with 34 international business class suites. Alaska launched Seattle-Rome service in April, becoming the first airline to offer daily flights on that route. Service to Reykjavík begins 28 May, completing Alaska’s initial European expansion.

Seattle Hub Becomes Transatlantic Gateway for Pacific Trade

Alaska Air Cargo launched dedicated belly-hold freight service on the London route the same day passenger flights began. The daily schedule creates a novel east-west corridor for UK and European shippers looking to reach Asian markets via Seattle rather than traditional eastbound routings through Middle Eastern or Asian hubs.

Des Vertannes, managing director of Wexco Cargo GSSA, noted the shift: “From the UK and Europe, when you’re looking at those Asian Pacific connections, you naturally look east. To have Seattle as a hub and Alaska Airlines is a novel option. We now have a new direction, new routes to explore and a new focal point.” Expected commodities include seafood, auto parts, health products and broadcasting equipment, with import demand boosted by Seattle hosting matches during this summer’s World Cup.

Fourth Largest US Global Carrier Targets Dozen International Routes

Alaska Airlines became the fourth largest global carrier in the US and 15th largest worldwide following its 2024 combination with Hawaiian Airlines. The merged entity operates from seven hubs including Seattle, Honolulu, Portland, Anchorage, Los Angeles, San Diego and San Francisco, serving 110 cities globally with plans to reach 550 aircraft by 2035.

The airline targets at least a dozen long-haul international destinations from Seattle by 2030, with LAX service to Guatemala and Costa Rica also planned. Alaska operates daily widebody service to Tokyo Narita, Seoul and Honolulu, with connections to Sydney, Osaka and Tokyo Haneda through the Honolulu hub. The carrier is the only US airline running dedicated freighters between Seattle and Alaska daily, maintaining cold-chain logistics experience built over more than 90 years.

$41,000-Square-Foot Lounge Investment Signals Premium Push

Alaska will open the largest airline lounge in Seattle in late 2027, spanning over 41,000 square feet across two levels with approximately 700 seats. The lounge investment accompanies new facilities in Portland opening summer 2026, with San Diego and Honolulu lounges scheduled for early 2028.

Andrew Harrison, Alaska’s chief commercial officer, said the expansion brings “West Coast hospitality to every step of the journey” for European passengers, while US travellers gain “more convenient access to Europe with the airline they know and love.” The carrier is installing Starlink Wi-Fi across its entire fleet, including 100% of widebody aircraft by autumn 2026.

Industry Perspective: Hub Strategy Opens Multi-Leg Routing Options

Alaska’s Seattle hub model creates competitive routing alternatives for forwarders assembling complex UK-Asia itineraries. Traditional eastbound Europe-Asia lanes face capacity constraints and premium pricing on high-demand routes. A westbound option via Seattle adds price competition and schedule flexibility, particularly for shippers moving time-sensitive goods that benefit from daily departures.

The combined Alaska-Hawaiian network brings over 90 years of cold-chain expertise and remote-community service to the transatlantic market. Ian Morgan, Alaska’s vice president of cargo, emphasised the connectivity: “We can connect from Japan or South Korea to Europe via Seattle, while still serving cargo needs throughout the West Coast and more remote places like Hawaii and communities in Alaska that no one else can serve like we can.” Forwarders booking multi-carrier, multi-leg routes need platforms that compare airport-to-airport and door-to-door options across carriers quickly to capitalise on new routing opportunities as they emerge.
