There is a fast lane actually for "pre-check" passengers. I got in that line last time we flew, though my wife had to go in the slow line. I must have gotten in it via the random factor (you can sign up for it apparently) - there was something extra printed on my boarding pass. It was great. No one was in the line and I didn't have to remove my shoes or belt or take my laptop out of the bag. In and out like the wind. Then I had to wait on the other side for my wife.
