Key Takeaways:

Delta is expanding its international non-stop service from Seattle with new routes to Rome (four times weekly) and Barcelona (three times weekly), launching in May 2026.
These new flights will be operated by Airbus A330-900neos and will feature premium seating options.
The move puts Delta in direct competition with Alaska Airlines, which also recently announced new Seattle-Rome flights.

Delta currently flies nonstop from Seattle to three destinations in Europe – London, Paris, and Amsterdam. It also serves several markets in Asia, including Taipei, Tokyo, and Seoul.

Earlier this month, Alaska announced new flights between Seattle and Rome as the carrier looks to bolster its long-haul network from the city. Rome will be the airline’s third long-haul route, joining Tokyo Narita and Seoul.
