Anyone carry on hubcaps on a domestic flight? I picked up 4 nice original 14" caps correct for a 69 Dodge Coronet in Florida and want to take them onboard an American flight from Orlando to San Jose via DFW. They stack just under nine inches high and are about fifteen inches around. Overhead gets pretty vicious with the panicking late boarders and I'm not sure if they will go under the seat. Supposed to have an MD80 for both flights. Advice please. Should I just ship them. No dents or scuffs and they have the factory paint on them so I want damage free shipping. Will they be ok on the Security check conveyer?
