The newly formed Alaska Air Group is wasting no time in making its mark.

In May 2025, the group will launch the first of 2 new routes from Seattle (SEA) to Toyko-Narita (NRT) followed by nonstop service from Seattle to Seoul (ICN) in September.

“We believe our guests will be as excited as we are about these new nonstop flights to Tokyo and Seoul – two of the world’s most dynamic cities,” said Ben Minicucci, chief executive officer at Alaska Air Group.

Here are the details of these exciting new routes.

Hawaiian Will Fly Nonstop From Seattle to Seoul and Tokyo

It’s an exciting time for frequent Alaska, Hawaiian, and Oneworld flyers based in Seattle, thanks to the new Alaska Air Group.

The first Hawaiian-operated flight from Seattle to Narita will take to the skies on May 12, 2025.

The schedule, which has the same Seattle departure time as the Japan Airlines service, is as follows:

Depart Seattle (SEA) 1:30 p.m. — Arrive Tokyo (NRT) 4 p.m. (+1)
Depart Tokyo (NRT) 6:25 p.m. — Arrive Seattle (SEA) 11:30 a.m.

Honolulu-based travelers will be glad to learn that this won’t negatively impact services to Tokyo. In fact, the Alaska Air Group plans to operate an additional 2 weekly frequencies on its route to Haneda (HND), Tokyo’s second airport.

The Seoul launch is scheduled for September 12, 2025, and will be operated by the A330-200, though the 787 is expected to eventually join the route:

Depart Seattle (SEA) 3:25 p.m. — Arrive Seoul (ICN) 6:50 p.m. (+1) (Wednesday to Sunday)
Depart Seoul (ICN) 8:50 p.m. — Arrive Seattle (SEA) 3 p.m. (Thursday to Monday)

This is just the start of Alaska Air Group’s plans for nonstop flights to 12 long-haul global hubs from Seattle by 2030.

Hot Tip:

In addition to new flights and schedule updates, Alaska and Hawaiian’s merger has brought about changes to their frequent flyer programs, which you can read all about here.

Domestic Connectivity Is a Focus for 2025

As of March 2025 and the official start of the northern hemisphere’s aviation summer programming, the Alaska Air Group will be making changes to its domestic schedule. This is to streamline connectivity and provide a better variety of departure times for domestic passengers.

Updates will include more capacity from the group’s West Coast focus cities of Portland (PDX), San Diego (SAN), and Seattle to Hawaii.

A specific focus will be on San Diego, which will welcome additional services to Kahului (OGG) in Maui and retimed midafternoon and redeye departures.

Additionally, there will be additional frequencies on the Maui to Portland and Honolulu to San Francisco (SFO) routes, which the group hopes will facilitate better connectivity between Hawaii and the East Coast.

Final Thoughts

The merger of Alaska and Hawaiian is already bringing positive changes for U.S. travelers, both nationally and internationally.

While some might be frustrated by the decision to only operate the Toyko service nonstop from Seattle to Tokyo rather than both ways, the route is certainly a step in the right direction.
