Everything you need to fly Origin to Destination: timing, airlines, and insider tips.
3x Weekly Seasonal
Flown by Delta
Delta Air Lines is expanding its transatlantic network with a highly anticipated direct connection between the Pacific Northwest and the heart of Catalonia. Starting in the summer of 2026, travelers can fly non-stop from Seattle-Tacoma International Airport to Barcelona-El Prat, eliminating the need for connections in traditional hubs like Amsterdam or Paris.
This seasonal route operates three times weekly, bridging the 5,000-mile gap between Seattle and Barcelona. By utilizing the modern Airbus A330-900neo, Delta offers a premium experience for travelers heading to Spain for the summer season.
“Previously, travelers from Seattle had to connect through other major US or European gateways to reach Barcelona. This direct service significantly reduces travel time and provides a specialized link for the tech and tourism sectors that connect these two vibrant coastal cities.”
