SEATTLE – Seattle-Tacoma International Airport (SEA) revealed today 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.

“We have a clear vision for how the airport will look and feel in the coming years,” said SEA Managing Director Lance Lyttle. “Making your experience less stressful and more predictable is at the center of our vision. You can feel the difference now at the newly modernized N Concourse and soon to open International Arrivals Facility. The C Concourse Expansion is what’s next in how SEA serves travelers, and we can’t wait.”
