Chase Plans Massive 16,000-Square-Foot Sapphire Lounge at Seattle-Tacoma International Airport in a $70 Million Premium Travel Expansion

Chase is aggressively expanding its footprint in the competitive airport lounge sector, with newly surfaced Port of Seattle documents revealing plans for a massive, 16,000-square-foot Chase Sapphire Lounge at Seattle-Tacoma International Airport (SEA). The proposed facility, which represents a substantial multi-million-dollar investment, would occupy a prime location in the airport’s Concourse A, directly positioning the credit card giant’s signature hospitality brand adjacent to major competitor Delta Air Lines.

The blueprint for the expansive new lounge, first brought to light by aviation blog View from the Wing, is scheduled for a formal vote by the Port of Seattle Commission. If approved, the project will transform the landscape of airport amenities at SEA, offering premium travelers a heavily upgraded space featuring Chase’s signature blend of sophisticated design, localized culinary offerings, and wellness-focused amenities.

A Closer Look at the Proposed SEA Sapphire Lounge Layout

According to architectural renderings and planning documents submitted to the Port of Seattle, the proposed Chase Sapphire Lounge in Concourse A is designed to be one of the most ambitious spaces in Chase’s growing network. Spanning two levels across an impressive 16,000 square feet, the facility will incorporate a wide array of high-end amenities tailored to modern frequent flyers.

Among the standout features outlined in the documents are made-to-order dining and artisanal beverages accessible directly from travelers’ seats via QR code ordering. This touchless, seated service model has become a hallmark of the Sapphire Lounge experience, distinguishing Chase’s properties from traditional buffet-heavy airline clubs. In addition to culinary stations, the plans include dedicated shower suites for freshening up between long-haul flights, quiet zones, family rooms, and a striking signature bar.

Perhaps most intriguing for premium travelers and spirits enthusiasts is a specialized space designated in the renderings as a “Collector’s Lounge.” Furthermore, architectural designs tease a semi-outdoor terrace—a rare and desirable feature for airport lounges, offering passengers fresh air and dynamic views of the airfield. The aesthetic direction follows Chase’s established design language: an elevated, residential-inspired interior that feels more like a boutique hotel than a standard airport terminal waiting area.

Background and Evolution of Concourse A Development

The emergence of the Chase Sapphire Lounge proposal marks the latest chapter in a complex, multi-year saga regarding the allocation of premium real estate in SEA’s Concourse A. The origin of the current development phase dates back to May 2022, when the Port of Seattle Commission initially approved a sweeping expansion project aimed at increasing premium lounge capacity.

Under the original 2022 agreement, the port intended to construct a two-story Delta Sky Club while simultaneously expanding an existing, Priority Pass-accessible independent lounge known as “The Club SEA,” located across from Gate A11. That initial vision materialized in late 2025 with the grand opening of a massive new Delta Sky Club, which notably included a dedicated 10,000-square-foot Delta One Lounge on its upper level, catering exclusively to long-haul business class passengers.

However, the companion project to expand The Club SEA ran into severe headwinds. Construction plans stalled significantly, and the port ultimately scrapped the original expansion concept late last year. By that point, public funds had already sunk approximately $34 million into the initial build-out of the stalled Club SEA footprint.

Faced with millions in sunk costs and an incomplete facility, Port of Seattle leadership sought an alternative financial and operational strategy. Inviting Chase to take over the space offered a viable exit strategy. Under the proposed terms, partnering with Chase relieves the port of the remaining financial burden required to finish the original lounge build-out. Additionally, projected revenue from the long-term lease agreement with Chase is expected to fully offset and pay off the historical construction sunk costs by the year 2043.

To accommodate the displaced independent lounge, the Port of Seattle has devised a contingency plan. If the Chase Sapphire Lounge proposal wins commission approval, the existing operations of The Club SEA will eventually relocate to a nearby space in Concourse A that United Airlines is scheduled to vacate in 2027. This secondary space requires a significantly smaller and less expensive build-out than the sprawling 16,000-square-foot footprint dedicated to Chase.

Timeline and Implementation Challenges

While the architectural plans and financial structures are largely detailed in the public commission documents, eager travelers will likely have to exercise patience. As of the public disclosure, neither Chase nor the Port of Seattle has established a definitive timeline for construction or a grand opening date.

Logistical hurdles dictate that the project will take considerable time to complete. Before Chase can even begin demolition, interior restructuring, and expansion work, the current occupant—The Club SEA—must be successfully transitioned out of the space across from Gate A11. Given the complexity of modern airport infrastructure projects, industry analysts estimate that travelers should not expect the doors of the Seattle Chase Sapphire Lounge to open for at least a year, if not longer.

Access Rules and the Shifting Economics of Airport Lounges

The rapid proliferation of Chase Sapphire Lounges—with nearly ten locations either open or in active development nationwide—has significantly altered the competitive landscape of premium travel rewards. Understanding the access policies for these facilities is crucial for cardholders navigating airport terminals.

The primary and most cost-effective gateway to the Chase Sapphire Lounge network is the Chase Sapphire Reserve® card. Cardholders possessing the Reserve card enjoy complimentary access for themselves, along with guest privileges that typically include two complimentary guests per visit. Furthermore, authorized users added to the account receive their own independent access and guest allowances.

Travelers holding the legacy Ritz-Carlton Credit Card from Chase—a metal card that is no longer open to new applicants but remains active for existing cardholders—also enjoy complimentary entry privileges with up to two guests.

However, broader access policies have tightened significantly across the industry. Chase recently adjusted its rules to eliminate a popular loophole that previously allowed travelers with Priority Pass memberships issued by competing financial institutions, such as American Express or Capital One, to visit Sapphire Lounges once per calendar year. Under the revised policy, visitors who do not hold a qualifying top-tier Chase credit card must purchase a single-entry day pass, which runs $100.

Strategic Implications for the Competitive Landscape

The addition of a 16,000-square-foot Sapphire Lounge in Seattle represents a calculated strategic move by Chase. SEA has evolved into a fiercely contested aviation hub, particularly dominated by Delta Air Lines and Alaska Airlines. By planting a massive, luxury-tier lounge directly in Concourse A—steps away from Delta’s premier facilities—Chase is signaling its intent to capture the lucrative market of high-spending business and leisure travelers in the Pacific Northwest.

For the Port of Seattle, the partnership provides a fiscally responsible resolution to an expensive development misstep, transforming a stalled public investment into a long-term revenue generator. For travelers, the potential addition of a world-class Sapphire Lounge promises to inject much-needed capacity and elevated dining options into an airport that frequently experiences high passenger volume and crowded terminal conditions.

The final decision now rests with the Port of Seattle Commission during Tuesday’s scheduled vote. Should the commissioners greenlight the proposal, Seattle will officially secure its place as home to one of the largest and most ambitious bank-branded airport lounges in the United States.
