The North Satellite Modernization Project is the expansion and renovation of a 45-year-old facility to better serve passengers with more choices and amenities for an enhanced travel experience. This investment by the Port of Seattle and Alaska Airlines will be built to preserve resources and meet our strict sustainability standards. The entire venue will open up with natural light and views of the airfield and mountains, befitting of a world-class airport.

January 2019 update:
Five new gates are now open as the first of several milestones in the expansion phase of the project. With the 240-foot expansion of the building to the west, these new gates allow construction to take place in stages to minimize impact to passengers during the renovation.
Additional sections of the building will open in the next four months, including an upper level mezzanine, four new eateries, additional gates, and a flagship Alaska Lounge. Passengers can currently enjoy the brand-new seating with built-in charging stations.
