Alaska Airlines is transforming Seattle-Tacoma International Airport (SEA) into a global gateway with the launch of new nonstop flights to Tokyo Narita (NRT) and Seoul Incheon (ICN) in 2025. Partnering with Hawaiian Airlines, this major expansion strengthens the international network of Alaska Airlines while boosting connectivity across the West Coast. These new routes position Seattle as a premier international travel hub, offering more global access than ever before.

New Nonstop Flights From Seattle To Asia

Starting May 12, 2025, Alaska and Hawaiian Airlines will begin daily nonstop service from Seattle (SEA) to Tokyo Narita (NRT) using the spacious Airbus A330-200 aircraft from Hawaiian Airlines. This route is now available for booking on alaskaair.com and hawaiianairlines.com. Nonstop flights from Seattle (SEA) to Seoul Incheon (ICN) will follow in October 2025, with tickets going on sale in early 2025.

The Alaska Airlines hub in Seattle already serves 104 nonstop destinations across North America, making it the largest West Coast hub for any airline. With this expansion, Alaska plans to operate at least 12 long-haul international routes from Seattle by 2030, further connecting the Pacific Northwest to the world. Potential future international destinations include London, Paris, Madrid, Hong Kong, Manila, Bangkok, and Delhi [not confirmed].

Here is how Alaska Air Group CEO Ben Minicucci describes the new Seattle strategy:

“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. From our global gateway in Seattle, we can conveniently connect travelers from across our network as they head to Asia and beyond. Hawaiian’s spacious widebody aircraft, along with its excellent onboard service and amenities, will make for a terrific trip from one side of the Pacific Rim to the other.”

In tandem, Hawaiian Airlines will adjust its Hawaii – Japan service by increasing flights from Honolulu (HNL) to Tokyo Haneda (HND) while maintaining nonstop service to Osaka (KIX) and Fukuoka (FUK). These strategic moves allow the airline to better match aircraft capacity with travel demand across the Pacific.
