Just arrived at South Terminal entrance - I was early so figured I'd check it out. Lots of people but tons of staff around to keep things organized - DL, airport, and CLEAR staff all helping.
I've been in a Clear+Pre line about 7-8 mins and looks like I'm maybe 1/3 or 1/4 through. They are saying the full line is 30-35 mins.
So it's a wait, but much better than what the news was showing this morning. When I arrived I figured if I'd used the Intl terminal I'd either be waiting for Pre to open or spending an extra 10 mins coming back to A Concourse.
