Some international airports won’t allow your regs in carryon. Rightly so
I have never understood the US obsession with all dive gear as carry on- maybe I’m missing somthing
My dive gear flies internationally 4-6 times a year...
To the original question. I’ve seen carryons weighed once, often they can see by the size of the bag and the way you lift it if it’s overweight
