AvGeeks traveling to, from, or transiting through Seattle-Tacoma International Airport (SEA) will soon have access to a relatively rare amenity, at least in the Pacific Northwest of the United States: an observation deck, albeit one that’s airside so it’s only available to ticketed passengers.

Currently expected to open to the traveling public in the second quarter of 2026, the expanded concourse will add at least 10 restaurants to the airport’s offerings, several new retail outlets, some fancy new seating, and lots of artwork. The signature artwork for the new spaces is a very large wood sculpture of a stylized tree, which will arch over an interesting stadium-style seating area.

But, back to what’s most exciting for the AvGeek crowd – the Lookout at C, as the airport is calling it. It’s a glassed-in observation area, looking west-southwest from the C concourse toward the main terminal and the airport’s taxiways, some of the gate areas, and SEA’s three runways.
