I have always taken my wristwatch off if I had to go through the body scanner. 3 trips ago, I forgot and was already in the tube and TSA guy in Milwaukee says it's fine to leave it on. OK, so for the last 6 flights I've left it on w/o a problem. Milwaukee, Seattle & Vegas. My brother left Milwaukee on Saturday and they made him go back because he left his watch on Just curious what happens at your airport? What do you do? In the big picture it's not a big deal, just wondering since it's raining again and the grass won't get cut again. Oh and speaking of the TSA, my wife filled her 1 qt baggie with booze minis and had no problems either way.
