Phase 3 Guidance for Port Construction Now in Effect 
Effective March 22, 2021, King County entered Phase 3 of Governor Inslee's Healthy Washington — Roadmap to Recovery plan. This did not change construction guidance from previous phases, and all construction continues under the Governor’s construction safety guidance. The Port of Seattle reviews and monitors job site safety plans for all construction in compliance with Governor Inslee’s Proclamation 20-25 and Phase 2 construction guidance. Visit our COVID-19 Updates for Port Construction page for details.

The North Satellite Modernization Project is the expansion and renovation of this 1970s 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.

Phase 2: In Progress

The Phase 2 renovation of the existing facility features 12 remodeled gates, a Central Marketplace with a flagship restaurant, nature-inspired art installations, and the airport’s first fully-integrated pet relief area. The renovated interior includes new building forms and functional interests that are cost-effective, environmentally friendly, and improve accessibility through thoughtful design considerations. Renovation highlights include:

  • More dining and retail spaces like Filson, Pike & Pine and sodoPop!
  • More than doubling the space in the entire facility to 468,000 square feet
  • Dramatic open space with natural light in a nearly 80-foot-tall Central Marketplace
  • Nature-inspired art celebrating Pacific Northwest ecology

Construction of Phase 2 will be completed in mid-2021.

As part of Phase 2, we're renovating the old facility to make it remarkably brighter and higher! In this video, Resident Engineer Oliver Konkel explains what that means and what travelers will see when the new space opens this summer.

Phase 1: Complete

In July 2019, the Port of Seattle and Alaska Airlines celebrated the grand opening of the first phase of the new North Satellite, including the upper-level mezzanine with a flagship Alaska Lounge and Nursing Suite for traveling mothers. 10 new gates are open as part of the completion of phase one. Passengers can now enjoy the brand-new seating with built-in charging stations at each gate. 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.

Additionally, travelers can enjoy elevated dining and shopping experiences from the Pacific Northwest with four recent openings, including:

  • Caffé D’arte, a locally- and minority-owned, Italian coffee roasting company, serves high-quality espresso, drip coffees, pastries, sandwiches, and snacks. 
  • Bambuza Vietnam Kitchen is owned by husband-and-wife team, Daniel Nguyen and Katherine Lam, who highlight cherished family recipes, locally-sourced ingredients, and vibrant Vietnamese flavors in every dish. The name Bambuza pays homage to the bamboo plant, found throughout Vietnam.
  • Evolving from a scrappy Airstream food truck, Skillet is all about American comfort food prepared with classic techniques and seasonal ingredients. 
  • A modern-era travel retailer and newsstand for the reading and gift needs of passengers, The New Stand opened in North Satellite in the spring of 2019.
