The route will operate on Delta’s Airbus A321neo aircraft, offering a premium customer experience while supporting a more sustainable future of flying through operational efficiency and lower fuel usage. Delta continues to invest in a fuel-efficient fleet and recently received recognition from the Port of Seattle as having the highest percentage of fuel-efficient aircraft in use at SEA in 2023.
Delta also offers fast, free Delta Sync Wi-Fi onboard for SkyMiles Members throughout the flight, and all customers can enjoy a wide selection of in-flight entertainment options with Delta Studio movies, TV series, music, podcasts and more.
In addition to this new service to and from DCA, Delta has focused heavily on establishing SEA as a key gateway to Asia with routes to Tokyo (HND), Seoul (ICN), Shanghai (PVG), and most recently Taipei (TPE). As Seattle’s global airline, Delta offers consumers in the Pacific Northwest the most nonstop travel options to long-haul international destinations.
Customers can look forward to continued enhancements starting in spring 2025 as these routes transition to Airbus A350 aircraft with a total of 306 seats. These updates will provide about 55,000 more seats per year than the A330s currently operating on these routes and will increase premium seat options in Delta One and Delta Premium Select by 40%.
Additionally, in summer 2025, Seattle will become the 4th airport to feature a Delta One Lounge, complemented by the addition of a second Sky Club spanning more than 23,000 square feet on Concourse A.
