Current Initiatives

North Satellite

Expanding and renovating a 45-year-old facility with more amenities, more elbow room, and sustainable design.

Setting foot into Sea-Tac’s North Satellite facility will mean stepping into natural light, views of the airfield and mountains, and enjoying more offerings of a world-class airport.

The expansion and modernization of the North Satellite will make room for eight new gates for additional flights each day. The renovation includes a new rooftop-level Alaska Airlines lounge with Olympic Mountain views, improves the Concourse C Satellite Transit Station,  and opens up the entire facility with natural light and views of the airfield and mountains.

Five new gates are now open as part of the expansion phase of the North Satellite Modernization Project at Sea-Tac Airport. Opening the 201,000 square foot expansion for limited service allows final construction to continue while giving passengers early access to more elbow room and brand-new seating with built-in charging stations at additional gates and waiting areas.

What’s more, the new North Satellite will offer double the dining and retail square footage, creating more choice for customers and more opportunities for local retailers and entrepreneurs.

To minimize the impact on travelers, construction will happen in two phases. Teams will expand the building from 160,000 square feet to 428,000 square feet, pushing 240 feet to the west and then adding a second story.

Beautiful design and more amenities for travelers

The expansion and renovation of the North Satellite will provide passengers with more choices and amenities. Inspired by Washington’s natural connection to the water, the wavelike articulated roof becomes a signature visual element bringing in natural light. The interior will feature wide, day-lit concourses constructed of materials, colors, and finishes inspired by the native Pacific Northwest environment. Inside, new dynamic, interactive signage, more robust Wi-Fi service, seismic upgrades, improved seating, and a refurbished transit system lobby will make for a more seamless and modern travel experience.

Sustainable from the start

The newly renovated North Satellite features energy-efficient and resource-friendly design elements. The building celebrates the ecology and environment of the Pacific Northwest, with a renovated interior that draws in more natural light, a new rainwater harvest system that supplies flushing water to the restrooms, and a nature-inspired "living wall" art piece of plants to complement the open design of the building.
