I'll be flying international into the US. I plan to opt-out from the body scanner while going through security in my own country, but I'm reading here
that you have to go through security again
when you get off the flight onto American soil.
So I'm asking - is this standard operating procedure? How does this work - do you have to carry your checked luggage with you, or do you go through customs post-security? Am I allowed to opt-out then?
I'll also be traveling with a person who's got several medical issues, one of them being type II diabetic that's controlled via diet, the other having to do with wearing a medical brace underneath their clothing - this person is also going to opt-out. Is this person allowed to carry some sort of granola bar or snack on their person in case the wait for a pat-down is long and their blood sugar starts to drop? Will this person be allowed to wear the brace while going through security or while getting patted-down? What about flying out of the US - is the security pretty invasive then too?
I know this is a whole lot of questions, but I'm looking for personal anecdotes from people who've flown internationally into the US recently - I'm somewhat anxious about what my companion might have to go through, and while I have no problem in waiting around, my companion's blood sugar levels don't have that luxury. (Please note: going through the body scanner isn't an option: my companion's history includes a fairly vicious fight with cancer along with a family history of cancer, and regardless of the current opinion regarding the safety of these scanners, our collective choice is to not go through them.)
