Just used Clear tonight at LAX T2.
There was an agent at the Clear lane at the bottom of the staircase who opened the rope to… the main staircase up to screening. At the top of the stairs, there was the regular Pre-Check lane with like 4 people and another roped-off Clear area with one person.
Needless to say, I made it through slower than if I would've stayed with the TSA Pre-Check ID line, as the four people were long gone by the time I finished up with Clear.
Seriously, all that just so you don't have to show an ID??
