Alaska Airlines Sets Launch Date for New Seattle-Seoul Route

After announcing plans for the flights last year, Alaska Airlines now has a date for its new Seoul service.

The airline will launch nonstop service between its hub at Seattle-Tacoma International Airport (SEA) and Seoul Incheon International Airport (ICN) on Sept. 12, 2025 on Hawaiian Airlines, which it purchased for $1 billion last year. It will operate the route five times weekly on its Boeing 787 Dreamliner aircraft.

Alaska has long planned to expand in Seattle-Tacoma, where it is the largest airline, serving 104 nonstop destinations across North America. By 2030, it expects to offer 12 nonstop international routes from the airport, including the Seoul route and daily flights to Tokyo Narita International Airport (NRT), which will start on May 12.

“With our robust network, we can connect our guests through our global gateway in Seattle for convenient nonstop service to Seoul and Tokyo, with additional connections to other Asian destinations with our global partners,” said Andrew Harrison, chief commercial officer at Alaska Airlines. “As we grow our global network from Seattle in the coming years, we’ll announce new international routes to dynamic destinations that we know our guests are going to love to visit.”
