Turns out there was supposedly a bomb discovered in one of the parking garages. They shut down three terminals while they investigated it. We got to the airport at 7:45, and they shut everything down at 8:30. They wouldn't even let people arrive at the terminals to be dropped off.
We got off the ground 90 minutes late, and made up all but 15 minutes in the air. Good flying! :)
We're in Seoul waiting for our flight to Vlad. Can't wait!
