Seattle–Tacoma International Airport (SEA/KSEA) is Alaska Airlines' primary hub, located in SeaTac, Washington. The airport handles roughly 50.9M annually and is a major operating base for Alaska Airlines, Delta Air Lines. Travelers connecting through SEA have access to 8 airport lounges spread across 7 terminals or concourses, including some of the most highly regarded card-issued and airline-operated lounges in the United States.
The airport sits in SeaTac, Washington and is well connected to the surrounding metropolitan area by interstate, light rail, and rideshare. Most travelers heading to a lounge should pass through TSA security at their assigned terminal first, then follow signage for the relevant concourse. Plan to arrive at the lounge entrance at least 60 to 90 minutes before boarding to take full advantage of the food, drink, and shower facilities.
Lounge programs available at SEA include American Airlines Admirals Club, Alaska Lounge, British Airways, American Express Centurion Lounge, Delta Sky Club, Priority Pass, United Club. Below you'll find each individual lounge with its terminal, operator, access rules, and a current amenity list.
Insider tip: when planning a long connection at SEA, verify your boarding pass shows the correct terminal — and whether the lounge you plan to visit is post-security in your concourse. Some networks operate multiple locations within the same airport, and entering one and exiting through security to reach another can cost you 30+ minutes during busy periods.
For travelers planning a longer layover at SEA, lounges with shower suites and quiet rooms are highlighted in the listings below. Standard guest policies apply for each program; expect to pay $45–$75 for additional guests at most card-issued lounges. Day-pass options vary, so confirm pricing with the operator before relying on a paid walk-up.
