I flew a couple days ago and it wasn't anything extraordinary. Typical 15-20 minutes and that was in the Elite line. I usually try to avoid security at C2 seems like C2 is always the worst. The security people will sometimes try and force you to use a certain line but i usually walk through whichever works best. Just tell them your going to the PC at C1 or the one by C3 if those lines are shorter.
