Seattle-Tacoma airport expands concourse C ahead of 2026 World Cup

Alaska Airlines is set to be the largest tenant in Concourse C, alongside Horizon Air and Hawaiian Airlines. Monty Anderson from the Seattle Building and Construction Trades Council highlighted that SEA's investments have created numerous jobs and opened opportunities through apprenticeships for underrepresented groups.

Port of Seattle Commission President Hamdi Mohamed emphasized the project's role in job creation and sustainability efforts aligned with the Port's Century Agenda goal of becoming North America's greenest port.

Airport Managing Director Lance Lyttle discussed SEA's spatial constraints and how vertical expansion addresses these challenges by providing new amenities like restrooms, lounges, sensory rooms, a nursing station, and a solarium offering views of airfields and mountain ranges.

An extension to SEA's ramp tower is also included in this expansion to manage ground operations effectively. Lyttle stressed that growth is essential for maintaining service levels as demand increases due to regional population growth.

Lyttle stated: "We know that we are one of the most space-constrained airports in the country... By adding four new floors to C Concourse, we’re able to provide a much higher level of service desired by our customers."
