When your TikTok "viral travel hack" gets you barred from the flight you're ticketed for and escorted out of the airport.
When I traveled all the time, I own a jacket that literally had about two dozen pockets in it. Handy!
I have never been denied boarding nor escorted out of ANY airport.
@mcfate got escorted out once for having a kubotan, I mean c'mon. But let through when I had three cooking knives in my winter coat. Different times.
Anything remotely weapon-like ALWAYS got put into checked luggage. Keeps life simple.
