Delta Air Lines increases capacity on several transpacific routes from Seattle-Tacoma to key markets in South Korea, Japan, and Taiwan.
Starting on the 29th, Delta Air Lines will operate Airbus A350-900 aircraft to Seoul-Incheon and Taipei, marking the first time this model has been used in Taiwan. For the summer 2025 season, it will have six daily flights with the same aircraft to the South Korean capital, making it Delta’s transpacific destination with the highest seat capacity offered.
Beginning May 23, 2025, the A350 will be introduced on the route to Tokyo-Haneda. Previously, this model operated to Narita between 2019 and 2020. The A350 will replace the Airbus A330-900neo on all these routes, allowing for an increase in premium seats.
The configuration used for these A350s will be the standard 306-seat layout: 32 Delta One Suites, 48 Premium Select, 36 Delta Comfort+, and 190 Main Cabin.
Additionally, one of the two flights on the Atlanta-São Paulo route will be operated with an Airbus A350-900, replacing the A330. This is the third destination in South America to use this model after Santiago de Chile and Lima.
The configuration employed will be the premium A350 layout with 275 seats: 40 Delta One Suites, 40 Premium Select, 36 Delta Comfort+, and 159 Main Cabin.

Competition in Seattle-Tacoma
This move by Delta comes after Hawaiian Airlines, in partnership with Alaska Airlines, announced their first long-haul services from Seattle, launching flights to Tokyo-Narita and Seoul-Incheon next year.
Delta has led the long-haul market in Seattle-Tacoma for years and is preparing strategies to compete with Hawaiian and Alaska in this segment.
