SEA Previews Incredible Improvements Ahead with C Concourse Expansion

Seattle-Tacoma International Airport (SEA) revealed 30 percent design renderings of its next marquee capital improvement project. The C Concourse Expansion will elevate SEA, literally, by adding four additional floors above the existing building and raising the bar on the airport experience and sustainability. 

The project spans the C and D Concourses with 145,530 more square feet of dining and retail, sought-after amenities such as an Interfaith Prayer and Meditation Room and Nursing Suite, and an all-new, more than 20,000-square-foot Alaska Airlines Lounge. The heart of the space – The Grand Stairs at C – will be an iconic destination that invites travelers to linger with seating, airfield views, music and art, or head upstairs for more elbowroom and dining and retail options. The expansion also encompasses office space for airport businesses, airlines, and the TSA.
