My last time through there was one TSA agent checking IDs for elites and PreCheck and he was stationed outside security with the other agents checking the regular line. You really couldn't pass anybody because it was one line for both.

In the past, they would have you snake your way far to the right and check IDs way beyond the normal security entrance and there they had some signage for PreChecks only on the far right.

Hopefully, they will go back to the old ID checking station as that seemed to work better.
