I'm not sure what's up lately. Maybe I just haven't seen this very much, but twice in the past two weeks I have seen people getting the full body check at gates prior to departure. Last week at ORD, a woman was extremely unhappy being told that she had to wait for TSA and wouldn't be allowed to board until she was screened -- and the flight wasn't going to be held for her. She had been at ORD for four or five hours on a layover apparently and was pulled out of line for the treatment.

Today at IAH, I saw two guys getting the treatment before boarding.

What's going on? Are these SSSS tickets that got missed? Or are these SSSS BPs that got issued to connecting pax? (And that makes no sense whatsoever.)
