Delta Air Lines will launch a daily nonstop service between Seattle-Tacoma International Airport and Tokyo Narita from late March 2027, using an Airbus A330-900neo. The route is scheduled to begin with Seattle departing on 27 March 2027 and Narita departing on 28 March 2027, extending Delta’s transpacific network from Seattle and restoring its link to Narita after a gap of several years.
The new service will complement Delta’s existing Seattle–Tokyo Haneda operation, giving the carrier service to both major Tokyo airports from its Pacific Northwest hub. Delta describes the addition as its most comprehensive Seattle–Tokyo offering to date and positions Seattle as a key gateway for its Asia network.
The route will operate as DL115 from Seattle at 13:35, arriving in Narita at 16:20 the following day, with the return DL114 leaving Narita at 18:30 and reaching Seattle at 12:00. Delta’s Japanese-language material links the launch to broader Pacific growth and highlights Seattle’s connections to more than 50 North American cities. The airline has not disclosed fares, and booking availability details remain limited.
