She’s right. Go home and then start the arduous process of trying to get your luggage back. Good luck!
Actually, they would have never let his luggage on the plane.
I would suggest going home too, except for the fact that the plane tickets to get this far of course cost an arm and a leg that isn’t going to be refunded now, so, it’s either accept the lost and wasted money, or get on the flight anyway.
My dad got stopped when he had two big 8 day cuckoo clock weights in his carryon. Looked like hand grenades in the xray. They are shaped like big fat pinecones.
By abandoning your flight and leaving now would likely get you back on the list for suspicious behavior.
