TSA began their Pre-Check screening (or lack thereof) at LAX on Jan 17. I have GE and signed up when I received the invite from AA a few months back. I have been lucky enough to use this process 3 times now (thanks to the double DEQMs). I used it the first day they began the process on 1/17. I can tell you it was very smooth, but that may be because they really didn't know what they were doing......It was quick though, belt and shoes stayed on, computer and liquids stayed in the bags, coat however, because it was large, was removed. Total time to process through TSA screening? Less than 2 minutes! I used the pre-check again on 1/19 with similar results and again today, 1/25. Today however, it seems they were back to square one...confused about allowing those qualified to actually use the pre-check line...I actually got into a bit of an argument with one of these uber intelligent TSA folks who told me emphatically they "Did not have a pre-screened process"...but after I requested she speak with her supervisor, actually came back and ushered me into the pre-screen line (no one in line) and off I went through the screening process in under a minute and off to the AC! Does anyone else have any experience using this new process?
