Delta Air Lines has announced plans to introduce new international routes from Seattle-Tacoma International Airport. The airline will begin flights from Seattle to Rome on May 6, 2026, followed by a route to Barcelona on May 7, 2026. This move comes shortly after Alaska Airlines revealed its own nonstop service from Seattle to Rome, marking its first branded long-haul operation.
Alaska Airlines holds a significant market share in Seattle and recently acquired Hawaiian Airlines. This acquisition allows Alaska to expand its intercontinental routes using widebody aircraft previously ordered by Hawaiian. In response, Delta is intensifying its focus on Seattle as a key hub.
Delta's new routes will be operated with Airbus A330-900 aircraft, configured with various seating options including DeltaOne suites and Premium Select seats. These additions will bring the total number of European destinations served by Delta from Seattle to five.
