The new all-in-one Delta Sky Club and Delta One Lounge at Seattle-Tacoma Airport (Sea-Tac) is defined by its height. The magnificent, two-story space has a soaring roof and towering columns. Even the bathroom stall doors seem unusually tall.

And whether you’re in the Delta Sky Club on the lower floor or the even more exclusive Delta One Lounge on the top floor, the high ceilings and giant windows give everyone an elevated experience. In fact, if you want a taste of a first class lounge experience without buying a first class ticket, the Delta Sky Club on the lower floor is probably as close as you can get.

I was invited to a media preview of the lounge before the Delta Sky Club opened to the public on June 25, 2025. The Delta One lounge opens June 26, 2025.

Here’s what it was like inside.

The new Delta Sky Club and Delta One lounge at Sea-Tac is located near gate A11. Guests will enter through a set of automatic sliding doors, check in at the front and then ride the elevator to either the third floor for the Delta Sky Club or the fourth floor to the Delta One lounge.

The Delta Sky Club at A11 is open from 5:00 a.m. to 10:30 p.m. The Delta One lounge at A11 is open from 8:30 a.m. to 8:00 p.m.

Delta will also retain its existing lounge, which is located just down the A concourse, closer to gate A1 and the B gates.

Though the two lounges are in a connected space, there are separate entry requirements for each one.

• Cardholders with The Platinum Card® from American Express, The Business Platinum Card® from American Express, Delta SkyMiles® Reserve American Express Card or Delta SkyMiles® Reserve Business American Express Card. Terms apply.

• SkyTeam airline premium cabin passengers.

• Delta Diamond, Platinum or Gold Medallion members traveling internationally in Delta Premium Select or Delta One.

In all cases, you’ll need a same-day boarding pass for a Delta flight or an eligible flight on a partner airline.

Meanwhile, Delta One Lounge access is restricted to:

• Passengers departing or arriving with a same-day Delta One ticket.

• Same-day departing or connecting flights in Air France La Premiere and Business Class (long-haul), LATAM Premium Business Class, KLM Business Class, Korean Air First Class and Prestige Class or Virgin Atlantic Upper Class.

There are no credit cards that can get you into a Delta One lounge. However, you can use Delta SkyMiles or its partners’ miles to book a qualifying ticket to gain access to the Delta One lounges.

The two-story lounge is built similar to an atrium, with the second-level Delta One lounge overlooking the Delta Sky Club below. It feels spacious, but it could get noisy when it’s at capacity. The 14,000-square-foot Delta Sky Club has 183 seats, while the 10,000-square-foot Delta One lounge has 221 seats.

Both levels have many seating options, from square solo booths to long, communal tables. And the electrical outlets to recharge electronics are plentiful.

The design also pays tribute to the Emerald City in color scheme and materials. This lounge is accented with emerald and navy tones, as well as some visually compelling wavy wood structures to echo the water and forests surrounding Seattle.

On both levels, natural light pours in from the windows on two sides of the lounge and offers views of Mt. Rainier (hidden behind a Hilton DoubleTree hotel and clouds in the picture below), a small lake, a corner of the tarmac and the light rail line.

The Delta One lounge lets guests perch right next to the windows on a huge, covered wraparound outdoor terrace.

The Delta One lounge’s outdoor terrace has plenty of seating (72 outdoor seats in all) and because of the lounge’s location on the edge of the tarmac, it’s not as loud as other outdoor airport spaces where the whining of airplane engines drowns out any peace you might’ve momentarily found.

The Delta Sky Club on the lower level is all indoors, but similarly, it offers plenty of spaces to enjoy the scenery, with armchairs and tables lining one wall of windows. The other wall has an eye-catching bar that’s one step lower than the main floor to avoid obstructing the view.

The buffet on the Delta Sky Club level has an impressive variety for just three islands of food. When I visited, there were sandwiches, salads, charcuterie, and hot food, including mac and cheese and chipotle BBQ ribs.

The general manager of the Delta Sky Club told me that the clam chowder from the Seattle chain Ivar’s is so popular at the previous Sky Club location that some travelers purposefully plan a layover in Seattle to have a taste.

There’s also a dessert table for travelers hankering for something sweet. Some of the offerings may include coconut cream pie and marionberry crumble.

Around the corner from the buffet is the drink station with an array of hot and cold drinks. The coffee bar features a local coffee roaster you might have heard of — Starbucks.

And the bar serves complimentary cocktails, beer and wine.

The Delta One lounge features an la carte menu, table service and an open kitchen to watch the magic happen.

There are some good Asian-inspired dishes on the menu, including sticky pork ribs glazed in hoisin sauce and edamame dumplings. I was also impressed with the dishes that feature locally sourced seafood, such as the delicious Dungeness crab stuffed cannelloni, a stuffed pasta dish.

For dessert, Delta One guests can order options, such as the Rainier cherry sundae (the best type of cherry hands-down) or a cheese plate from Beecher’s, an iconic Seattle cheesemonger.

The coffee on the Delta One lounge level is sourced from Caffe Umbria, and the baristas can even customize your latte for special occasions.

Each lounge has its own set of restrooms with several individual toilet stalls. The mirrors and doors are very tall in the bathroom, which again, fits with the entire lounge’s vertical design.

There are showers available to guests of both lounges, but the showers are located on the Delta Sky Club level. There’s a kiosk where you can sign up for a shower time slot. The bathrooms are stocked with Grown Alchemy products, and the showers include some extra amenities like a robe and a vanity kit.

The combination of two lounges in one space is a first for the airline. The design will go a long way in making both lounges feel spacious, even during crowded times (which there are sure to be).

With other airlines racing to build new premium lounges and larger flagships, it seems like out-lounging Delta will be a tall order.
