Delta launches new nonstop Seattle-Tokyo Narita route starting March 2027

Delta Air Lines announced it will launch a new nonstop route between Seattle-Tacoma International Airport (SEA) and Tokyo-Narita International Airport (NRT) starting in late March 2027, giving travelers a second direct way to reach Tokyo from the Pacific Northwest.

The new service will run alongside Delta’s existing nonstop flights between Seattle and Tokyo-Haneda International Airport (HND), giving customers two distinct paths into Tokyo depending on where they need to go in the city or beyond. 

Delta also flies to Haneda from several other US cities, including Atlanta (ATL), Detroit (DTW), Minneapolis-St. Paul (MSP), Los Angeles (LAX), and Honolulu (HNL).

Narita as second daily nonstop option to Tokyo from Seattle

Jeff Arinder, Delta’s Vice President of International Network Planning, said Japan remains one of the airline’s most important and popular destinations, and that adding Narita service gives travelers more flexibility when planning trips. 

He said flying to both Haneda and Narita allows Delta to offer more overall capacity and two convenient ways into Tokyo, backed by the strength of the airline’s broader U.S. network.

Port of Seattle Commissioner Toshiko Hasegawa echoed that sentiment, pointing to the long-standing relationship between Japan and the Pacific Northwest built through trade, tourism, and cultural exchange over generations. She said expanding service to both airports gives travelers more options while reinforcing those economic and cultural ties.

The new Seattle-Narita route will operate daily using Delta’s Airbus A330-900neo aircraft, which includes the airline’s full suite of long-haul cabins: Delta One, Delta Premium Select, Delta Comfort, and Delta Main.

Seattle’s growing role as a global gateway

The announcement builds on Delta’s broader investment in Seattle, where it remains the largest international carrier. 

The airline currently operates more than 160 peak-day departures to over 62 destinations from Seattle, including recently added nonstop routes to Barcelona (BCN) and Rome (FCO). 

Eligible Delta One customers departing Seattle can also access the Delta One Lounge before their flights.

While the new Narita route originates in Seattle, its reach extends further, since SEA serves as a key West Coast connecting point for travelers from across the US heading to Japan. 

For business travelers, the added flights support continued demand between the two countries, while leisure travelers gain more flexibility to explore Tokyo and destinations beyond it.

The route also complements Delta’s joint venture with Korean Air, which connects travelers to 15 destinations across Japan, including Osaka and Sapporo, via Seoul-Incheon.

Route details

The Seattle-Narita service is scheduled to launch March 27, 2027, operating daily aboard the Airbus A330-900neo. 

Combined with existing Haneda service, Delta will now offer customers two nonstop options for flying from Seattle to Tokyo. Flights are expected to go on sale soon at delta.com.

Beyond passenger travel, the new route will add cargo capacity between Japan and the US supporting freight demand between two major commercial markets. Delta noted that Narita’s cargo infrastructure makes the route a useful addition for its cargo customers as well.
