Alaska Lounge Sea Concourse
★4.4(514 reviews)SEA
Alaska's newest Seattle lounge, next to gate C16 — membership or day pass.
The Alaska Lounge in Concourse C is the newest of Alaska Airlines' three Seattle-Tacoma lounges, sitting on the mezzanine level next to gate C16. Alaska is the largest carrier at SEA, so its lounges are the natural home base for its passengers. Access is via Alaska Lounge or Lounge+ membership, eligible Alaska First Class and qualifying partner premium passengers, or a day pass bought subject to space. The lounge carries Alaska's signature self-serve touches — a pancake machine, freshly brewed coffee and espresso, soup and salad, light bites and a bar — alongside fast Wi-Fi, power and a mix of relaxed and work-friendly seating.
Crowding · busy at peak
A comfortable spot to work before a flight, with fast Wi-Fi, power at many seats and seating you can use for a laptop. Fine for email and light work, though it isn't a dedicated business lounge.
Alaska Lounges lean on a tidy self-serve spread rather than a full hot buffet — soup, salad, light snacks and the popular make-your-own pancake machine, plus barista-style coffee and espresso. The bar serves beer, wine and spirits, with some local Pacific Northwest pours.
