Delta Air Lines to Resume Seattle-Tokyo Narita Service in 2027, Challenging Alaska Airlines

Delta Air Lines is preparing to reinstate nonstop flights between Seattle-Tacoma International Airport (SEA) and Tokyo Narita International Airport (NRT) after a seven-year hiatus. The Seattle-based service had been halted in 2020 amid the COVID-19 pandemic, and its return marks a significant expansion in Delta’s transpacific network from Seattle, also complementing its daily flights to Tokyo Haneda (HND).

The new SEA–NRT service is slated to begin in late March 2027, although an exact launch date remains undisclosed. Scheduled departure times indicate a 1:30 PM local takeoff from Seattle, arriving the following day at Narita around 4:20 PM. The eastbound leg will depart Narita at 6:30 PM, reaching Seattle the next day close to noon. This timing offers convenient afternoon departure and midday arrival options for transpacific travelers.

While Delta’s Haneda route utilizes Airbus A350-900 aircraft, the reintroduced Narita flights will be operated by Airbus A330-900neos. The A330-900neo configuration includes Delta’s premium Delta One business class with 29 lie-flat seats in a 1-2-1 layout, 28 seats in Delta Premium Select premium economy, and 224 seats in the main cabin, which includes 56 Delta Comfort seats offering extra legroom. The total passenger capacity stands at 281.

Delta’s Vice President of International Network Planning, Jeff Arinder, emphasized that offering service to both Tokyo airports provides travelers with more choice and increased capacity. This dual-hub strategy leverages Delta’s extensive U.S. network and strengthens its connectivity to one of its most important international destinations.

The SEA–NRT route reinstatement also sets the stage for direct competition with Alaska Airlines, which officially launched nonstop flights from Seattle to Tokyo Narita in May 2025. Alaska, operating initially with Hawaiian Airlines’ A330-200s before introducing its Boeing 787-9 Dreamliners, is Seattle’s largest carrier overall and a dominant Pacific Northwest competitor to Delta.

This will be the fourth long-haul market from Seattle where Delta and Alaska Airlines compete on nonstop service, alongside London, Seoul, and Rome. Delta further operates multiple international flights from Seattle to European destinations like Amsterdam, Paris, and Barcelona, as well as Asia destinations including Shanghai and Taipei. Alaska plans to expand its international long-haul Seattle routes to at least 12 by the end of the decade.

Delta describes itself as the largest international carrier at Seattle, boasting over 160 peak day departures to more than 62 destinations. The renewed focus on Seattle as a transpacific gateway is part of Delta’s broader commitment to serving key global markets and increasing its presence in Northwest U.S. aviation.

The reintroduction of the Seattle-Narita route represents a notable development in the competitive dynamics of the Pacific Northwest’s international air travel market. With Delta deploying modern widebodies and offering premium cabin options, travelers from Seattle will have significantly more diverse choices for flights to Tokyo starting in early 2027.
