North Sea-Tac Airport Renovation
(NorthSTAR)

The North Sea-Tac Airport Renovation (NorthSTAR) is an unprecedented working arrangement between the Port of Seattle and Alaska Airlines with the goal to better serve passengers. The 40 year-old north satellite has seen only limited upgrades during its lifetime and is in need of modernization, renewal and replacement of many of its basic systems.

NorthSTAR will provide upgrades for travelers and employees from airport drop-off to flight departure. This investment by the port and Alaska, now the sole tenant in the north satellite, will include modernizing current facilities, seismic upgrades, enhanced traveler amenities, new gates, a roof-top lounge for Alaska Airlines, plus long-term energy savings and improved operational efficiency.NSat06_21_12.jpg

Project Highlights

NorthSTAR brings together the north satellite renovation and several parallel projects, including main terminal improvements, refurbished north satellite baggage systems, and new exterior walkways, stairs and elevators
  • Complete renovation of the north satellite passenger boarding level to include more natural lighting, open circulation areas and unobstructed views
  • Enhanced passenger amenities will include redevelopment of dining and retail offerings tailored to the preferences and needs of the Pacific Northwest traveler.
  • Technology upgrades with new dynamic, interactive signage and more robust Wi-Fi service
  • Current plans include a rooftop Alaska Airlines Board Room with views of the Puget Sound area
  • Additional aircraft gates
  • Refreshed north satellite transit system lobbies
  • Aircraft tri-taxi lane changes around the north satellite
  • Refurbishment of the baggage handling system
  • Add access walkways, elevators and stairs
  • Main terminal improvements
Alaska Airlines will continue to use concourses C and D for operations, which will also receive specific upgrades. The renovation will be completed in stages in order to minimize impacts to passengers during construction.
