Beware: SeaTac Delays Today

Currently sitting on a plane scheduled to take off 35 minutes ago. Pilot just announced that they have shut down one of the runways (reason unclear), and so all arriving and departing planes are using the same runway. There are 22 planes ahead of us for takeoff and we have been delayed by at least an hour and a half, but potentially more. Be aware that any flights in or out of SeaTac today will likely be delayed as long as that runway remains closed!
