Last spring, I flew with a box of business cards. Apparently, that box looked like something dangerous or suspicious, based on the reaction of the screening agent.
He advised me that next time I should put that sort of thing in an easily accessible place, rather than the bottom, of my carry-on. He had to basically unpack my bag to get to the item he wanted to check. In fact, he seemed more freaked out than the time I shoved all my cables and chargers into a tangle in my backpack.
I don’t know whether that’s new, because I’ve been flying with books for, well, forever. But maybe it was the fact that it was a perfect rectangle and not really book shaped.
