United Airlines Commits $21 Million to New Seattle Lounge

New Seattle Lounge Development Underway

United Airlines is proceeding with a new two-story lounge at Seattle-Tacoma International Airport (SEA), representing an investment of $21 million. The Port Commission authorised a $15.5 million reimbursement agreement with United, allowing construction to commence. Work is scheduled to begin in the third quarter of 2026.

The 7,181-square-foot facility will occupy the former American Express Centurion Lounge space across from gate B3, aligning with United’s relocated gate operations in Concourse B. The Port’s schedule indicates the lounge will enter service in the fourth quarter of 2027, though staff informed commissioners that substantial completion is anticipated in December 2027, suggesting a more probable opening in 2028.

This development follows United's operational shift to Concourse B in November 2025, necessitating the replacement of its former Concourse A Club.

Facility Features and Cost Breakdown

The new United Club is a complete two-story build-out, not merely a repurposing of the previous space. It will include a full-size kitchen, family rooms, and views from both concourse and mezzanine levels. Interior details will feature terrazzo flooring, decorative wall paneling, and ceiling artwork, reflecting United’s updated lounge standards.

The total project cost of $21 million includes $15.5 million for construction, which the Port will reimburse to United. An additional $5.752 million covers design, Port-controlled contingency, project and construction management, and other supplemental expenses. This translates to an all-in cost exceeding $2,900 per square foot.

The Port of Seattle noted that the project’s cost increased by $3.252 million from an earlier $18 million estimate in 2021, attributing the rise to construction cost inflation and changes in the final design.

Strategic Upgrade Reflects Evolving Standards

The Port of Seattle stated that United’s lounge standards have changed significantly since its previous Concourse A Club, near gate A9, was constructed. That 6,096-square-foot facility opened in 2013. The replacement lounge in Concourse B is designed to support current product offerings, such as substantially more hot food, rather than the older lounge standard.

While the Port was contractually obligated to provide a like-for-like replacement following United’s move, the airline opted for betterments beyond this requirement, funding features like terrazzo, wall treatments, and ceiling art.

The new lounge’s larger footprint and enhanced amenities are intended to align directly with United’s current operational footprint in Concourse B, placing the lounge immediately adjacent to its gates B7A, B9, B11, and B15. The former A9 Club remains operational for the interim period.

Business Participation Goals

The United Club project at SEA includes a 19% "aspirational goal" for participation by women- and minority-owned businesses. The Port of Seattle clarifies that this goal applies to locally-funded Port contracts, distinct from federal guidelines.

Federal Department of Transportation programmes have suspended race- and sex-based preferences following constitutional challenges, requiring business owners to demonstrate individual social and economic disadvantage. However, the Port maintains that its aspirational goal, funded by airport revenues derived from airline charges, falls within its independent authority.

Washington state law prohibits preferential treatment based on race or sex in public contracting. The Port argues that an aspirational goal encourages outreach and documented efforts without mandating the selection of a specific bidder or making utilisation a condition of contract.

The Washington state attorney general supports aspirational goals, outreach, and training, provided they do not lead to less-qualified contractors being chosen.

Implications for Travellers and Industry

For travellers flying with United Airlines from Seattle-Tacoma International Airport, the new lounge signifies a substantial upgrade in ground services.

Upon its anticipated opening in late 2027 or 2028, passengers can expect modern amenities, expanded dining options with a full kitchen, and dedicated family areas, reflecting a broader industry trend towards premiumisation of airport lounges.

This significant investment by United, supported by the Port of Seattle, demonstrates the airline’s commitment to passenger comfort and aligns its lounge offerings with its updated brand standards.

Industry observers will closely monitor how this substantial capital outlay influences passenger loyalty and perceived value for United’s services in a key West Coast hub, as airlines increasingly compete on ground facilities to differentiate their premium offerings.

This move also highlights the ongoing evolution of airport infrastructure to meet changing airline and passenger demands.
