Delta will launch new non-stop service from Seattle to Barcelona and Rome – four times per week to Rome and three times per week to Barcelona – beginning summer 2026. Whether exploring the vibrant streets of Barcelona or the timeless landmarks of Rome, customers will enjoy a seamless journey aboard the next-generation Airbus A330-900neo, featuring Delta’s premium cabin experiences.
Delta One offers lie-flat seats with full-height privacy doors, direct aisle access and curated inflight meals paired with premium wines. Delta Premium Select offers a more spacious seat, adjustable footrest and leg rest, upgraded dining and an amenity kit, all designed to make long-haul travel more comfortable and refined.
Delta has launched 28 new markets in Seattle over the past decade and now operates nearly 180 peak-day departures to 60+ global destinations. Through Delta’s global alliances, customers have access to hundreds more across Europe, Asia, and Latin America.
For the first time ever, Delta is opening two lounges in one separate-but-connected space. Situated across from Gate A11, the two-story space features over 24,000 square feet of panoramic mountain views, sophisticated design and premium offerings to suit every customer. This is the fourth Delta One Lounge added to the network in the past year and the third new Delta Sky Club, bringing the total of Delta lounges and clubs to 57.
To enhance the Delta One Lounge experience, Delta One customers flying out of SEA now enjoy an exclusive, concierge-style Delta One check-in; similar experiences are offered at BOS, JFK and LAX, with plans to expand to all Delta hubs. Starting June 25, eligible passengers flying in any cabin who check in via the Fly Delta app and enroll in TSA PreCheck Touchless ID (formerly Delta Digital ID) can access expedited bag drop and security lanes, with this benefit rolling out to all Delta hubs by year’s end.
Perched on the top floor, the Delta One Lounge offers an exclusive retreat with seats for 149 guests inside and 72 seats on a wrap-around terrace with breathtaking views of Mt. Rainier. Just below, the Delta Sky Club seats 183, where expansive windows showcase the surrounding mountains and forests.
Complementing these enhancements, Delta has secured priority access to 18 gates across Concourses A and B—streamlining operations and ensuring a more seamless, elevated experience for travelers from check-in to take-off.
