How bad is the PreCheck line?
We where there 3-4 weeks ago, Precheck took ~5 minutes. Our flight was delayed, so we went to the Priority Pass lounge. I twas in concourse 4 and our flight was in concourse 3, so we had to go through security twice, it wasn't bad either time.
(Although it was annoying that you cannot get from concourse 3 to 4 without leaving security.)
