I guess I've been very lucky with the TSA. Mainly San Diego, Phoenix, Dallas and Dayton. Phoenix they seem so slick on a Sunday afternoon you don't have time to put your case down while waiting in line before you're moving. Dayton, somewhat pedantic. I guess they're not ueed to pax going international. San Diego, no problem. DFW, they were fast and efficient and polite.. Does it help if you travel Business or First Class? don't know, except that travelling First internally, you appear less likely to get a SSSS on your boarding card than if you're travelling economy - which in view of 9/11, seems crazy. But we are talking about an agency that seems to have stupidity of its top management as a primary requisite.
At the end of the day, I still think it gives employment to a lot of people without enhancing security. Regrettably, pax have to pay for it........
