The Port of Seattle has formally approved a new Chase Sapphire Lounge at Seattle-Tacoma International Airport (SEA), signing off on a 15-year lease for a roughly 16,000-square-foot space in Concourse A. View from the Wing broke this story through its own reporting.
The approval, which came on a Tuesday, follows a commission vote in September that had to be postponed after two commissioners were absent, leaving only three present. With the full commission convened, the lease was passed and the project can now move forward.
What the Port Has Agreed To
Under the terms of the 15-year lease, the airport stands to receive around $135.6 million in rent over the course of the agreement, according to View from the Wing. A total of $70 million has been earmarked by Chase for the initial construction and a midterm refurbishment, a figure that underlines the scale and long-term nature of the bank's commitment.
Airport Dimensions is Chase's partner on the project and was selected through a competitive process. The firm has worked with Chase on its existing lounge network, and its involvement here signals a consistent approach to how the bank builds and operates these spaces.
Airport staff presented a 24-slide deck to commissioners ahead of the vote, covering what lounges are, how Chase operates, and the financial case for approval, according to View from the Wing. That level of groundwork reflects how much scrutiny the project attracted before it reached a final decision.
Where the Chase Sapphire Lounge Will Sit and What Will Move
The new lounge will occupy the current space of The Club at SEA in Concourse A, plus an adjacent area, positioning it next to the Delta lounge complex, which includes both a Delta One Lounge and a SkyClub. That cluster of premium spaces in Concourse A is set to become a significant draw for cardholders and frequent travellers transiting that part of the terminal.
The moves do not end there. One Mile at a Time reports that The Club at SEA will itself relocate into the space currently occupied by the United Club, while the United Club moves to the former American Express Centurion Lounge space in Concourse B. It is a chain of relocations that reshapes the lounge landscape across multiple concourses at SEA.
What Passengers Can Expect Inside
Planned amenities include shower suites and digital food ordering, according to One Mile at a Time. Access to Chase Sapphire Lounges is primarily available to holders of the Chase Sapphire Reserve and Sapphire Reserve Business cards.
Seattle will join Los Angeles and Miami as Chase Sapphire Lounge locations in the pipeline that are not yet open, per One Mile at a Time. The network of card-linked lounges continues to expand as financial institutions compete for premium travel spend.
The Questions Commissioners Asked
Not every commissioner was fully satisfied before the vote. Commissioner Toshiko Hasegawa questioned how setting aside terminal space for a subset of travellers aligned with the Port's equitable development mission, according to View from the Wing. Commissioner Hamdi Mohamed raised a more commercial concern: whether passengers eating inside the lounge would be less likely to spend at the airport's wider restaurant offering.
Airport staff tackled that second concern head-on, presenting data showing that lounge visitors were no more likely than the general passenger population to skip food and drink purchases elsewhere in the terminal. They also cited the American Express Centurion Lounge at SEA as a comparable example, pointing out that concession revenues in the surrounding areas had continued to rise following its opening, according to View from the Wing.
Those are reasonable questions for any port commission to ask when leasing large amounts of terminal space to a private financial product. The answers appear to have satisfied enough commissioners to secure the vote.

The Bottom Line
The Chase Sapphire Lounge at SeaTac now has a lease, a location, a partner operator and a substantial capital commitment behind it. At 16,000 square feet, a 15-year term and $70 million of planned investment, this is not a tentative entry into the market. The concourse shake-up that comes with it will change how several lounges sit within SEA's terminal layout, and the $135.6 million in expected rent gives the Port a clear financial rationale for the approval.
Whether the concerns raised around equity and restaurant competition resurface as the project progresses will be worth watching. For now, the deal is done and the build can begin.
