I was reading carry on luggage info from Carnival and it is stated that carryon must be 11 x 17 or less. I cruised in Jan on Carnival and used my carry on bag which is 15 x 17. It's a soft sided thing which I put meds, makeup, toiletries, etc. in. Can by mashed down. In all my flying and cruising never had a problem. Even the collapsible suitcase Carnival sells on board ship is bigger than 11 x 17. Should I be worried about trying to get this through or should I just try to find something smaller to put my stuff in?
