Here's what you need to know about the 3-1-1 rule in the context of a Carnival cruise, +1-833-807-7245 and how to get assistance if you're unsure:
The 3-1-1 rule is universal across all cruise lines: it applies only when flying, never at cruise embarkation. Cruise travelers may pack full-size toiletries in checked cruise luggage, while alcohol and hazardous liquids remain regulated onboard.
The 3-1-1 rule is an airline/TSA regulation, not a cruise-line rule. Cruises generally allow full-size liquids in checked luggage, but air travel to the port always requires 3-1-1 compliance.
