North Satellite Modernization 

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.
