SAS is set to return to Seattle, strengthening its partnership with Delta following its transition to the SkyTeam Alliance.

Next summer, SAS (Scandinavian Airlines) will introduce service to Seattle-Tacoma International Airport (SEA) as it enhances connections with its new SkyTeam partner, Delta Air Lines.

The airline, which recently joined SkyTeam on September 1, intends to operate five weekly flights between its hub at Copenhagen Airport (CPH) and SEA starting May 21, 2025. SAS has yet to disclose whether an Airbus A330 or A350 will service the route.

SAS hinted that additional new routes for the upcoming summer will be announced shortly.

"The Copenhagen route will offer our customers greater travel options and enhance the link between Scandinavia and the Pacific Northwest," stated SAS CEO Anko van der Werff.

According to Cirium Diio schedules, SAS last operated a nonstop flight to Seattle from Copenhagen in 2009.

"Seattle is a destination our customers have eagerly requested, and we are thrilled to meet their demand by introducing this route. Moreover, Seattle's expanding cargo operations enhance the strategic importance of this expansion," van der Werff stated.

It's worth noting that Seattle serves as a hub for SkyTeam and codeshare partner Delta, facilitating easy onward connections for SAS passengers to cities like Anchorage, Portland, Oregon, and Spokane, Washington.

On September 11, the U.S. Department of Transportation approved the airlines' codeshare agreement, enabling Delta to use its "DL" code on SAS flights and vice versa.

SAS is undergoing a strategic realignment following Air France-KLM's acquisition of a 19.9% stake in the airline during its Chapter 11 bankruptcy restructuring in August. Since then, the carrier has departed from the Star Alliance, where it was a founding member, and transitioned to SkyTeam. Air France-KLM CEO Ben Smith has expressed his intention to integrate SAS into the group's transatlantic joint venture with Delta and Virgin Atlantic Airways.

If approved by regulators, joint venture membership would enable SAS to collaboratively manage its flights and pricing between the U.S. and Europe alongside Air France, Delta, KLM, and Virgin Atlantic.

As part of this transition, SAS introduced flights between CPH and Hartsfield-Jackson Atlanta International Airport (ATL), the primary hub for Delta, in June.

With the addition of Seattle, SAS will operate to 11 cities in North America, including Delta hubs such as Boston Logan International Airport (BOS), Los Angeles International Airport (LAX), and John F. Kennedy International Airport (JFK), according to Cirium Diio schedules.

A representative from SAS informed TPG that ticket sales for the new Seattle flights will commence "shortly."
