The 10 best lounges at Seattle-Tacoma International in 2026

Seattle-Tacoma is a single terminal, which makes lounge hopping easier than at most hubs. Concourses A through D fan out from the Central Terminal and connect on foot, while the North and South Satellites sit at the end of a short train ride. Alaska dominates the North Satellite and Concourses C and D. Delta has built its West Coast showcase in Concourse A. International carriers and the Priority Pass crowd gather in the South Satellite. The train to a satellite adds a few minutes each way, so do not leave it late.

Ratings are Lounge Frog overall scores out of 5, with ties listed alphabetically.

1. Delta Sky Club (A)

The Delta Sky Club (A) scores 4.8, the top mark at Sea-Tac. It is upstairs in Concourse A near gate A1, with a full bar, four showers and about 350 seats. Hours are 4:15 in the morning to 11:15 at night. Members and eligible cardholders bring two guests at $50 each, with entry three hours before a same-day Delta flight.

2. Alaska Lounge (N)

The Alaska Lounge (N) scores 4.7 and is Alaska's flagship, opened in 2019 on the mezzanine above gates N13 to N18 in the North Satellite. The rooftop views are the draw, backed by a full bar, two showers and about 400 seats. Hours are 5 in the morning to 11 at night. Members bring two guests or immediate family, oneworld Sapphire and Emerald elites get in, and day passes cost $65 when space allows.

3. Delta One Lounge

The Delta One Lounge opened in 2025 and scores 4.7. It is on the upper level above the A11 Sky Club, wrapped by a 270-degree outdoor terrace, with a craft cocktail bar, two showers and 149 seats. Hours are 8 in the morning to 9:30 at night. Entry is for same-day Delta One passengers, Delta 360 members in Delta First and premium-cabin passengers on select SkyTeam partners. There are no guests unless you are a Delta 360 member, and no card or membership qualifies.

4. The Centurion Lounge

The Centurion Lounge scores 4.6 and is the easiest lounge to reach from any gate. It is on the Central Terminal mezzanine above the food court, opposite gate B3, with a craft cocktail bar, two showers and about 200 seats. Hours are 5 in the morning to 10 at night. Platinum cardholders pay $50 per guest unless they spend $75,000 a year, and since July 8, 2026, guests must be on the cardmember's flight.

5. The Club SEA (S)

The Club SEA (S) scores 4.5 and is the best Priority Pass lounge at the airport. Take the train to the South Satellite and the elevator next to gate S9 up one level. It has a full bar, two showers and about 100 seats, and it stays open from 6 in the morning until 1:30 at night. Priority Pass and LoungeKey members bring guests per their card, and day passes cost $60. Airline memberships are not accepted.

6. Alaska Lounge (C)

The Alaska Lounge (C) scores 4.3 and sits on the Concourse C mezzanine next to gate C16. It has a full bar and about 200 seats but no showers, and it closes early at 7 in the evening. Access matches the North Satellite lounge. It is fine for a quick visit, but the N lounge is worth the train ride if you have more than an hour.

7. British Airways Terraces Lounge

The British Airways Terraces Lounge scores 4.3 after a refresh. It is on the upper level of the South Satellite near gate S10, with a full bar and about 80 seats but no showers. Hours are 10 in the morning to 8 at night. Business class passengers enter without guests, and oneworld Sapphire and Emerald elites can bring one.

8. The Club SEA

The Club SEA scores 4.2 and is the Concourse A sibling of the South Satellite room, on the mezzanine across from gate A11. It has a full bar and about 100 seats, no showers, and the same long hours from 5 in the morning to 1:30 at night. Priority Pass, LoungeKey and DragonPass work here, and a day pass costs $50.

9. Alaska Lounge (D)

The Alaska Lounge (D) scores 4.1 and sits at the start of Concourse D, just beyond checkpoint 4 near gate D1. There is a full bar and about 200 seats, no showers, and hours from 5 in the morning to 11 at night. Reviewers rate it quiet and clean but find the coffee ordinary.

10. Delta Sky Club (A11)

The Delta Sky Club (A11) scores 3.8 and opened in 2025 across from gate A11, below the Delta One Lounge. It has a full bar, two showers and 183 seats, with hours from 5 in the morning to 10:30 at night. Guest rules match the A1 club. If both are open, the A1 club is the better room.

Where to look next

The full ranking is at the best lounges at SEA, each concourse is on the Seattle-Tacoma airport page, and the scoring is explained on the methodology page. One lounge was left out for lack of a photo: the United Club in Concourse A scores 4.2 and would have tied for eighth. The old Delta Sky Club in the South Satellite closed for good in 2021. Chase's planned Sapphire Lounge is still waiting on a Port vote.
