I get that nice TSA notice every other time I travel. Seems they don't like my curling iron. LOL They rifle through the bag making a mess and sometimes things don't all get back in my bag. I do now keep the iron on top so when they open the bag it is the first thing they see. They still rifle the bag, but not as badly and things haven't gone missing.

Why don't you put your curling iron in your carry-on if this happens so often? That way if a bag check is called for, you will be right there to oversee what is being left out of your bag.
