Alaska Airlines Goes Transatlantic: Schedules & Award Math

Alaska Airlines is no longer just a West Coast specialist. The carrier has launched Seattle-London, launched Seattle-Rome earlier this spring, and is scheduled to add seasonal Seattle-Reykjavík service on May 28, 2026. That turns Seattle into a real Europe gateway for Alaska flyers and makes Mileage Plan redemptions worth a fresh look.

The expansion comes with a broader premium push: 787-9 Dreamliners on London and Rome, a 737-8 MAX on Reykjavík, and a major lounge investment at Seattle-Tacoma International Airport. Below is the practical schedule, award-chart math, and connection strategy.

The Transatlantic Flight Schedule

Alaska’s European map now targets three distinct profiles: a primary business hub, a major leisure market, and an Iceland gateway with onward partnership utility.

Route	Departure Hub	Destination Airport	Frequency	Aircraft Type
SEA – LHR	Seattle (SEA)	London Heathrow	Daily	Boeing 787-9
SEA – FCO	Seattle (SEA)	Rome Fiumicino	Daily seasonal	Boeing 787-9
SEA – KEF	Seattle (SEA)	Reykjavík	Daily seasonal from May 28, 2026	Boeing 737-8 MAX

Mileage Plan Redemption Math

Alaska Mileage Plan now uses a distance-based award chart, which makes the exact route mileage matter. The headline: Seattle-London falls below the 5,000-mile threshold, while Seattle-Rome prices in the next band.

The table below outlines the one-way mileage requirements for Alaska-operated transatlantic flights based on these distance bands:

Route	One-Way Distance	Economy (Starting At)	Premium Economy (Starting At)	Business Class (Starting At)
SEA – KEF	3,622 miles	22,500 miles	30,000 miles	45,000 miles
SEA – LHR	4,798 miles	22,500 miles	30,000 miles	45,000 miles
SEA – FCO	5,619 miles	30,000 miles	40,000 miles	70,000 miles

Key Takeaway: Seattle-London sits just under 5,000 miles, placing it in the same lower redemption band as Reykjavík. If Alaska releases saver-level business awards, SEA-LHR at 45,000 miles one-way should be the sweet spot. Rome crosses into the 5,001-7,000 mile band, which raises the business-class floor to 70,000 miles.

Strategic Partner Connections

For onward travel beyond the nonstop gateways, Alaska’s oneworld membership and individual partnerships are doing a lot of the work:

• London (LHR): Seamless terminal transfers to British Airways for connection to Africa, India, and the Middle East.
• Rome (FCO): Connects to Oneworld partner Iberia and regional carriers for Mediterranean access.
• Reykjavík (KEF): Leverages Alaska’s long-standing partnership with Icelandair for secondary European markets not served by Oneworld.

Lounge Infrastructure Upgrades

To support premium international departures, Alaska is planning a large new Seattle lounge as part of a broader lounge investment.

1. New Seattle global lounge: Alaska says the planned C Concourse lounge will span more than 41,000 square feet, with roughly 700 seats across two levels.
2. Premium positioning: The upper level is expected to focus on international long-haul travelers, including Suites passengers and eligible top-tier Atmos elites.
3. Partner access: Alaska Lounge+ members, international business-class travelers, and eligible oneworld elites should also benefit from partner lounge access on international itineraries.

Bottom Line

This is more than a route announcement. Alaska is trying to turn Seattle into a credible long-haul gateway, and Mileage Plan members should watch award space closely. London is the obvious first target because it combines daily 787 service, broad partner connections, and the better distance band. Rome is more expensive on miles but compelling for nonstop summer travel. Reykjavík is the wildcard: a narrower aircraft, seasonal timing, and Icelandair connections could make it useful even without a lie-flat seat.
