I'll be up front and tell you I have not flown since prior to 9/11 so perhaps I am naive about the process. So I traveled from Nashville, TN to Charlotte, NC 12/8/11. Went through the scanner where you turn to the side and put your arms up. It showed a hot spot on my shoulder which they patted, it was nothing so I was on my way. I was thinking, not such a big deal! I traveled back from Charlotte to Nashville 12/11/11. At Charlotte, you initially walk through what appeared to be just an "old school" metal detector. It buzzed on my first walk through so they had me go back to walk through again after asking me if I had anything in my pockets or a cell phone on my person (I didn't). It buzzed the second time and the TSA agent told me he would need me to wait for him and walked me over to a 4-walled, clear sided cubicle sort of area. I thought I was just put in there to wait. After a minute or so, another TSA agent opened the other side of the cubicle and told me to come with him where he swabbed my hands. After that, I was told I was free to go. I was confused because I thought I would either be subjected to a scan or pat down. When I mentioned it to my husband who was flying with me, he said he thought I was being scanned when I was put in that cubicle. I'm not really mad about it, and I'm not sure what I would have chosen if I had been given the choice (a scan versus a pat down), but shouldn't it have been made clear to me that I was being placed in that room for a scan rather than merely placing me in a room and telling me to wait? I mean, how can you opt for a pat down if they don't tell you they are scanning you?! If they scanned me while I was in that cubicle, was it one of those more "informative" scans rather than the scans that just show hot spot areas they need to pat down (like the one in Nashville)? I'm really not sure what to think about this, but I can tell you I felt really odd after the fact thinking that I might have been scanned and viewed without even being aware of it.
