N Concourse Modernization

Status: Completed

With more room, more views, and more Pacific Northwest feels, the N Concourse Modernization project (formerly called the North Satellite Modernization) elevates the travel experience with the comforts you’re craving. In the newly renovated N Concourse, you'll find modern amenities, seismic upgrades, sustainable features, and improved building function. While you’re stretching out and exploring the larger and brighter space, just know there’s still more to come!

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.

Watch the livestreams from the event.

Summer 2021

The new N Concourse opened 10 more remodeled gates and a new airport destination in June of 2021 – the Marketplace at N, with a stage for live performances and open seating with airfield views. This early opening marks another significant milestone – the end of Phase 2 construction for the N Concourse Modernization project.

  • What’s still to come? Tundra Taqueria, SEA Roast Coffee House, and Pike & Pine have already opened and Filson should be opening in Dec. 2021! There are still a dozen or so more dining and retail options to open in 2022.

A Space Celebrating the Pacific Northwest

Surrounded by warm wood and sunlight, the new N Concourse celebrates the natural wonder that is the Pacific Northwest. The iconic building is designed to evoke the movement of a meandering river. 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.

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.
