The Tree at C and Grand Stairs to the right.<\/figcaption><\/figure>\n

Seattle-Tacoma International Airport (SEA) recently unveiled a $399 million, 145,000-square-foot expansion of the C Concourse and I had the opportunity to explore the space. I think passengers will be impressed and there is one new addition that AvGeeks will love!<\/p>\n

\"The<\/a>
An outside view of the new C Concourse expansion (on the left). Notice all the lovely windows.<\/figcaption><\/figure>\n

The overall space is quite striking. If you are familiar with C Concourse previously, you know it was cramped and a challenge to get through. As the number of passengers has grown, the airport has looked for creative new ways to expand, but it has been a challenge.\u00a0<\/p>\n

\u201cWe couldn\u2019t go out, so we have to go up,\u201d said SEA Airport Managing Director Wendy Reiter. \u201cUsing the same footprint, and not losing any gates, we\u2019ve created more comfort and utility for our travelers.\u201d And up they went. The new space is four stories tall, providing multiple levels of amenities, art installations, a sensory room, a performance area, and plenty of natural light.\u00a0\u00a0<\/p>\n

\"The<\/a>
The Tree at C, with the Grand Stairs. The colorful squares built into the Grand Stairs are called Table Art.<\/figcaption><\/figure>\n

The Tree at C instantly grabbed my attention and gave me vibes of the Pacific Northwest. The airport says that passengers \u201cwill feel the forest in the geometric patterns of Western Hemlock overhead that flow down an architecture centerpiece.\u201d I think that it looks rad!<\/p>\n

BONUS:<\/strong> Previewing the C Concourse While Under Construction in December<\/a><\/p>\n

Connected to the Tree at C are The Grand Stairs that serve a few purposes: they help connect the first and second levels, they act as additional seating, and they display the Table Art.\u00a0<\/p>\n

New dining and retail options were also added: Buffalo Wild Wings, Chili\u2019s, Nanny\u2019s BBQ, Bite Society, Great State Burger, Olympia Coffee, Port of Subs, Seattle Macaron Co, and Wanderlust.<\/p>\n

\"\"<\/a>
The Lookout at C provides great views of the airport and anyone is welcome to visit. <\/figcaption><\/figure>\n

I would say that the best part of the expansion is the Lookout at C. At the very top, you will find an area where you can take photos and watch airliners. The outside walls are glass, but there are a few inches of space between each pane, so it feels like you are inside and outside at the same time. Because of the openings, you can easily hear and smell all the airport operations, which is a huge benefit. Cheers to the airport for opting to put this feature into their plans!\u00a0<\/p>\n

\"There<\/a>
There were a few mascots running around and I had to get my photo!<\/figcaption><\/figure>\n

If you are flying through SEA (or using a SEA Visitor Pass<\/a>), it would be worth your time to check out the improved C Concourse and especially the Lookout at C. And if you have experienced it, let me know what you think in the comments.<\/p>\n
