BWI has somewhat improved. They gave me much less crap about opt outs. I haven't had to do in a month or so as I've successfully avoided the NoS with a SDOO.
SLC T1 has gone down the tubes. It used to be "pleasant" as far as TSA goes. Last month, the 2 striper copped an attitude with me when I insisted I see my stuff. Of course, a complaint backed that screener 100%. I did a SDOO yesterday but the lines were horrible for a midday Monday flight. This one 2 striper lady would not shut up. I understand she was trying to be helpful but she waaaay overdid it. Barking about how the line I was in was WTMD only, and if there were problems (metal implants, artificial joints, etc), they should just head on over now. Ironically, there were no signs saying that one could opt out at all, but there were several signs strewn throughout the checkpoint explaining how the NoS with the new "privacy" protection.
