Ive brought some really unusual shit onto planes before…
They almost always inspect my carry on, but I never have a problem with what im bringing. As long as you dont have a towel on your head you should be good to go. Any of the ‘searches’ they did on my carry on were always stunningly poor. You can see the guy on the x-ray machine all pissed that he cant see shit in there, and flags it for a guy to check. They see its a skinny white kid and dont really care.
