right but you gotta check your skis anyway, and the airline doesnt charge u for the boot bag too, it all counts as one.
so if you carry your boots, you gotta check your regular gear, at extra expense.
the cheapest way I figured is to pack all ski gear in boot/ski bags, then normal clothes in a small roller and messenger bag. then you only get charged for checking one bag.
would waaaaay suck if they lost your boot bag tho
