Experience SEA @ N
The airport celebrated the end of major construction of the N Concourse on Nov. 4, 2021, with an event filled with performances of music, poetry, and spoken word as well as speeches from SEA representatives and representatives from the teams instrumental in the construction progress of this new and improved facility. Later in the evening was also a panel discussion on Travel Trends.

A Space Celebrating the Pacific Northwest

Notice how the building forms, such as the ceilings and corridors, curve and bend. Explore new museum-quality art pieces that reflect the diverse environment, culture, spirit, and history of the region.
Marvel at Boundary, a life-sized version of the expanding root structure of an old-growth Western Red Cedar and SEA’s largest art installation to date. Artist John Grade shares his inspiration behind this exciting new piece.
All the Creature Comforts
With twice the space there’s more room to roam. Our remodeled holdrooms are keeping you connected with enhanced Wi-Fi and a charger at every seat to power up all your devices. Relax, admire the amazing mountain views, or check out the Alaska Lounge on the upper mezzanine level.
Hidden Sustainability Features
Did you know the flushing water in the N Concourse's restrooms uses rainwater collected from the roof, saving 2.8 million gallons of potable water annually! Sustainable building solutions just like this are incorporated throughout and help the facility earn credits to achieve a Leadership in Energy and Environmental Design (LEED) certification from the U.S. Green Building Council. The N Concourse Modernization project achieved a LEED Silver certification.

Project Timeline
Construction of the N Concourse Modernization project occurred in two phases. Phase 1 started with the 240-foot expansion to the west and eight new gates, which opened January 23, 2019. This was followed by the opening of the Alaska Airlines Lounge and official celebration of Phase 1 in July of 2019. Phase 2 renovated the old facility, including remodeling 12 of the 20 gates at the N Concourse, which opened June 29, 2021.
Estimated Project Costs
This investment by the Port of Seattle and Alaska Airlines is built to preserve resources and meet our strict sustainability standards. Funding for the project will come from a combination of airline fees and Airport Development Fund and Passenger Facility Charge revenues. As with virtually all airport projects, no Port of Seattle taxes will be used. The estimated cost for the N Concourse Modernization is $712 million.
