Deepening its investment in Seattle, Delta has announced new nonstop service from Seattle-Tacoma International Airport (SEA) to both Barcelona and Rome, along with the debut of two new premium lounges at SEA: a Delta One Lounge and a Delta Sky Club. Complementing these enhancements, Delta has also secured priority access to 18 gates across Concourses A and B—streamlining operations and delivering a more seamless, elevated experience for travelers from check-in to takeoff.
Service will operate four times per week to Rome and three times per week to Barcelona, beginning in summer 2026—opening the door to two of Europe’s most iconic destinations. Customers will travel aboard the next-generation Airbus A330-900neo, featuring Delta’s elevated 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 provides a more spacious seat with an adjustable footrest and leg rest, upgraded dining, and an amenity kit.
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. 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.
Located 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 views of Mount Rainier. Just below, the Delta Sky Club seats 183, where expansive windows showcase the surrounding mountains and forests.
The Delta One Lounge offers a Seattle-inspired fine-dining experience with an open kitchen, where guests can engage with chefs as dishes are prepared. The three-course menu highlights locally sourced seafood, from Dungeness crab cannelloni to wood-fired teriyaki steelhead, alongside dumplings, ramen and yellowtail crudo. Desserts include a Rainier cherry sundae, chocolate mousse and an artisanal cheese plate featuring Beecher’s flagship cheese.
Breakfast at the Lounge continues the Pacific Northwest theme with fresh pastries, Dungeness crab benedict and Dutch baby pancakes topped with Rainier cherry compote.
The regional flair goes beyond the plate—coffee is sourced from Seattle’s own Caffe Umbria. At the bar, guests can enjoy a selection of cocktails inspired by Seattle destinations, premium sake and a West Coast–focused wine portfolio.
The Delta Sky Club rotates seasonal specialties, offering zesty salads, hearty entrees like lemon chicken and ribs and clam chowder from Seattle’s iconic Ivar’s. Desserts include coconut cream pie and marionberry crumble. Like at all Delta Sky Clubs, guests can sit back and enjoy coffee from Starbucks—a hallmark of Delta’s wide-ranging partnership with the beloved Seattle brand. At the bar, cocktails, beer and wine are served, along with non-alcoholic options, with sweeping views of Mount Rainier in the backdrop.
Beyond its striking design, the space was created with sustainability in mind, featuring smart windows that adjust to sunlight, all-electric energy with motion-sensing lights, and reusable dinnerware to reduce waste. These touches help lower energy consumption while fostering an eco-friendly, comfortable, and elevated atmosphere.
These enhancements are matched by a broader commitment to sustainability in Delta’s Seattle hub: 87 percent of Delta’s CORE fleet and 70 percent of its ground support equipment at SEA are now electric. As a testament to Delta’s focus on enhancing sustainability initiatives across its operation at SEA, last year the Port of Seattle recognized the airline with a Sustainable Century Award for operating the highest percentage of fuel-efficient aircraft at the airport.
