On past cruises 5 or 10 yeas ago, we would buy a case of liquor in St. Thomas and bring take it on board an airplane ....as carry-on luggage. Now because of the restrictions, of one carry on and one small purse or laptop, I would imagine it wouldn't be possible to do this now. Can a case be checked.....? I also remember reading about some airlines that wouldn't allow anthing over 75 proof as carry on? Anyone hear anything about this?
