At check-in/bag-drop, we then ensure our BPs and Passports are in our individual, on-body, possession ... and they will have to be torn from our dead hands!
I shiver when some US TSA Agent insists I remove my passport from my pocket at the body-scanner (happened a few times) and place it on the belt for scanning ... NOOOOOOO!!! It’s too precious to be out of my hands!
