Not sure if 'true' PreCheck is setup for DL, but they are running expedited screening at all terminals. For all pax who get the three beeps when the BP is scanned, you get a laminated card which allows you to avoid the NoS, keep shoes, jacket, & belt on. Only thing that has to come out is your laptop and liquids.

I experienced it two weeks ago at MCI, and will be using it again tomorrow..
