Chase is preparing to bring its Sapphire Lounge network to Seattle-Tacoma International Airport (SEA) with a 16,000-square-foot (1,486 square-meter) facility planned near Gate A11, immediately adjacent to the Delta Air Lines lounge complex. The Port of Seattle is scheduled to consider a 15-year lease for the project on September 22, with documents presented to commissioners outlining the proposed credit-card lounge concession. Chase is expected to invest heavily in the initial build-out and a future midterm refurbishment.

The project will occupy the existing space used by The Club at SEA in Concourse A, together with an adjacent expansion area that had previously been planned for The Club. The arrangement is part of a broader reshuffling of lounges at SEA. The Club is expected to relocate into the United Club space that will become available when United Airlines moves to its new facility, allowing Chase to combine the existing footprint with the unused expansion space.

The proposed Sapphire Lounge will be considerably larger than the roughly 6,096-square-foot (565 square-meter) Concourse A facility currently occupied by The Club at SEA. The project combines that footprint with nearly double the expansion space previously planned for The Club, creating a substantially larger premium facility. Renderings submitted to the Port of Seattle show a purpose-built Sapphire Lounge environment rather than a simple refurbishment of the existing club. The design is intended to provide multiple seating environments, dining and bar areas, work-oriented spaces, and areas for passengers seeking a quieter place to spend time before departure.

The investment also reflects the scale of Chase’s commitment. Under the proposed agreement, Chase would spend about $70 million on initial construction and a midterm refurbishment. The airport would charge starting rent of $500 per square foot (0.09 square meters), generating about $7.9 million annually, with 10% increases scheduled in years six and eleven.

Chase Is Entering SEA Through A Lounge Shuffle

The Sapphire Lounge cannot simply take over an empty terminal space. Its arrival depends on several other moves occurring first.

United is developing a new Seattle club in the former American Express Centurion Lounge location, with plans to expand that footprint and add a second level. Once United moves, its existing Concourse A club becomes available. The Club at SEA is then expected to move into that vacated United space, freeing its current location for Chase’s project.

The sequence explains why the airport’s lounge landscape is changing even though the number of physical spaces is not increasing at every step. Existing facilities are being redistributed to accommodate larger, more specialized clubs. The Port of Seattle’s September 22 meeting agenda specifically identifies the transaction as a “Credit Card Lounge Lease Concession Agreement.” The meeting page lists both a memorandum and presentation for the proposal, although the meeting itself had not yet occurred when the project details were published.

The Location Puts Chase Beside Delta’s Premium Operation

The planned lounge will sit near the end of Concourse A, across from the current Club location around Gate A11. That places Chase immediately alongside Delta’s growing lounge presence, including the airline’s premium Delta One Lounge. The location gives the Sapphire Lounge access to a part of SEA already associated with premium international travel. It is also connected to the rest of the airport through SEA’s concourse system, although passengers departing from other areas will need to account for the additional walking or train journey. Chase currently identifies The Club at SEA’s Concourse A facility across from Gate A11 as accessible to passengers using Priority Pass.

For Chase, the move fills a notable gap in its West Coast lounge network. The company’s current Sapphire portfolio includes facilities in cities such as Boston, Dallas, Las Vegas, New York, Philadelphia, Phoenix, San Diego, and Washington, while Los Angeles and Miami are also in development. The Seattle project would therefore give Chase a substantial presence in a major Pacific Northwest gateway, while the airport gains another premium lounge option without requiring an entirely new terminal footprint.

For travelers, the biggest change will come after the relocation is complete. Eligible Chase Sapphire Reserve, J.P. Morgan Reserve, and Ritz-Carlton cardmembers currently have access to Chase Sapphire Lounges, and Chase also offers Priority Pass Select access through eligible cards. The proposed Seattle lounge would turn that existing card benefit into a dedicated facility at SEA. However, because construction depends on the surrounding lounge moves, the Port of Seattle documents do not yet establish a firm opening date.
