The C Concourse Expansion at Seattle-Tacoma International Airport (SEA) is a major step in the Port of Seattle’s effort to improve the travel experience and keep up with a rapidly growing number of passengers. The four-story, 110,000-square-foot addition expands on the existing 99,000-square-foot C Concourse building and turns one of the airport’s busiest hubs into a more spacious, welcoming and efficient destination.

The project reimagines how travelers move, rest and connect, introducing an expanded Gate C3 waiting area, vibrant new dining and retail options, and modern amenities such as a post-security sensory room, interfaith prayer and meditation room, a nursing room, and an public lookout. Behind the scenes, upgrades to baggage systems, loading docks and mechanical infrastructure enhance both comfort and operational performance.
