Over the past year or so, Delta Air Lines has been very nicely growing its network of Delta One Lounges, which are exceptional, among the best you’ll find in the US. So far, we’ve seen lounges open in New York (JFK), Los Angeles (LAX), and Boston (BOS).
There’s now an exciting update, as the fourth location in the network will be opening this week, in Seattle (SEA). Let’s take a look at everything we can expect.
Details of the new Delta One Lounge Seattle
On Thursday, June 26, 2025, we’re going to see the opening of the new Delta One Lounge at Seattle-Tacoma International Airport.
The new Delta One Lounge Seattle is located in an expansion of Concourse A, adjacent to gate A11. Note that all terminals at the airport are connected airside, so it shouldn’t be an issue to use this lounge regardless of where you depart from.
The Delta One Lounge Seattle will be open daily from 8:30AM until 8PM, covering most long haul departures from the airport, but not necessarily opening to those who may be connecting to another airport to catch a Delta One flight.
The Delta One Lounge Seattle is roughly 10,000 square feet, with seating for a total of 221 guests. So in terms of size, the lounge is around 50% bigger than the Boston lounge, around the same size as the Los Angeles lounge, and roughly one quarter the size of the New York lounge. Keep in mind that Delta’s long haul network out of Seattle isn’t that big, so I can’t imagine the lounge will ever get too busy.
The Delta One Lounge Seattle is located on the fourth level of the terminal, one level above the new Sky Club. Of the 221 seats, 149 seats are located inside, while 72 seats are located on a wraparound terrace, with views of Mt. Rainier.
As it’s described, the lounge’s design pays homage to Seattle’s natural beauty, with stone accents, rich wood paneling, and a palette of emerald, navy, rust, and warm wood tones. Metallic finishes and reflective glass are intended to mimic misty mountain peaks, while curated lighting is supposed to enhance the atmosphere.
As you’d expect, dining is a huge focus for any Delta One Lounge, with a restaurant style dining experience. I’ll talk a bit more about that below. When it comes to special amenities, the Delta One Lounge Seattle is lacking a bit, though. It doesn’t have a spa or wellness area, and for that matter, doesn’t even have showers (though the Sky Club underneath it does have two showers).
Below you can see the pictures that the airline has shared of the new Delta One Lounge Seattle.
Delta One Lounge Seattle food & drinks
Food and drinks are a huge focus for Delta One Lounges, with a particular focus on partnering with regional businesses.
The Delta One Lounge Seattle is described as offering a Seattle-inspired fine dining experience with an open kitchen. As a standard, the airline serves three course menus, highlighting 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 a cheese plate featuring Beecher’s flagship cheese.
Breakfast continues with the Pacific Northwest theme, with fresh pastries, dungeness crab benedict, and dutch baby pancakes topped with Rainier cherry compote.
Coffee is also sourced from Seattle’s 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.
Delta One Lounge Seattle access rules
The Delta One Lounge Seattle has the same access requirements as existing Delta One Lounges. There are essentially three sets of passenger who get access to Delta One Lounges:
- Same day departing or arriving Delta One ticketed passengers (this is the name of Delta’s premium business class experience); it doesn’t matter if you paid cash, redeemed miles, or upgraded
- Delta 360 members departing or arriving on a same day Delta first class ticket
- Same day departing or connecting passengers on flights operated by select Delta partners in first or business class; this includes passengers on Air France, LATAM, KLM, Korean Air, and Virgin Atlantic
As far as guesting policies go, guests aren’t allowed for those eligible for access, with the exception of Delta 360 members. Delta 360 members eligible for access may bring their immediate family (spouse or domestic partner and children under the age of 21), or up to two companions, for an entry fee of $100 or 10,000 Delta SkyMiles per person.
Note that while Delta Sky Club have a three hour access rule (whereby you can only access the lounge within three hours of departure, unless connecting), that doesn’t apply at Delta One Lounges.
Bottom line
The Delta One Lounge Seattle is opening on Thursday, June 26, 2025. This is an exciting development, and marks the fourth lounge in the Delta One network. Delta has really done a phenomenal job with its dedicated business class lounges, and I imagine this lounge won’t be an exception. I look forward to visiting!
