Based on this description, the AS Board Room at SEA was listed as landside with a question mark. "D Concourse, adjacent to security checkpoint."

Now AS has updated their website, modifying the description and including a map. "Concourse D, Near Gate D1."

So unless I hear objection from someone who knows, I'm removing it from the landside list. I would still welcome confirmation from someone who's been there.
