The current airline standard for carry on luggage is 45 linear inches (approx. 22 X 14 X 9) for airlines, but check with your particular airline for their maximum. Both domestic and international (international may change if you are flying regional airlines).
As far as ships go, luggage can be larger,but must fit through the security device, which is typically the same size as airline security scanners. The length doesn't matter quite as much as the width, but it's rare you will find luggage out of the typical measurements.
I have read here on CC that people have attempted to roll on their larger sized luggage and were directed back to the luggage drop-off area.
