N Concourse Modernization

Status: Completed Q4 2021

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!

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.

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.

Project Timeline

Major construction kicked off Q1 2017
Major construction finished Q4 2021

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 flagship 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. A final celebration to mark the end of major construction for this project took place November 4, 2021. 

Estimated Project Costs

The final estimated cost for the N Concourse Modernization is $712 million.

Funding for the project will come from a combination of Airport Development Fund and future revenue bonds. As with virtually all airport projects, no tax-payer dollars will be used to fund the project.
