I was out at Sea-Tac again this morning for a few hours and, for the most part, it was under control. The D/N checkpoint varied, but usually wasn't more than 10 people deep at the ID checkers. They've also opened the removable wall behind the QX/CO counters to revel an auxilliary checkpoint - that one had no wait. Interestingly enough, the C checkpoint, a few hundred feet away, was about 30-40+ people deep. Go figure.

As far as counter lines go, AS was about 3-6 people deep at each kiosk and QX had no waiting (as usual). CO's line wrapped around the back of the counter, as it looked like they only had 2-3 agents behind the counter. WN's line also wrapped behind their counter. NW was slammed and all their queues were full and they were moving the chairs by the windows and setting up additional ropes. I would guess CO and WN were probably about a 30+ minute wait and NW could've been over an hour, just judging by the number of people and the pace at which the lines were moving. HP/US, AA, HA, and F9 either had no line or just a few folks waiting.
