I went through TSA at DFW terminal D last week. The airline had gifted me with Pre Check but that service wasn't offered at that checkpoint so it was Pre Check lite. WTMD and x-ray. Quick and easy the way it should be but often is not. I can see first hand that TSA can run checkpoints well so the focus should be on demanding that level of performance 100% of the time. That goes back to faulty training, supervision, and leadership. I don't give Neffenger a snowballs chance in hades to fix that problem.
