When you arrive at the Port Authority Security in the cruise terminal, you will pass a security checkpoint where all carry-on luggage goes through X-rays and other baggage is checked in. All checked bags on cruise ships are scanned.

Yes, cruise ships have highly rigorous security scanning for all luggage, similar to airport security but often more focused on specific "onboard safety" risks. When you arrive at the cruise terminal in 2026, your checked bags are taken to a backstage area where they are processed through large X-ray scanners to check for prohibited items like weapons, fire hazards (such as irons or candles), and unauthorized alcohol. Most cruise lines also employ "scent dogs" to detect illegal drugs. Your carry-on luggage goes through a smaller X-ray machine at the security checkpoint where you board the ship, and you must also pass through a metal detector. In 2026, many cruise lines use AI-enhanced scanning technology that can easily identify "hidden" bottles of liquor inside mouthwash containers or other decoys. If a prohibited item is found, the bag will be flagged, and you will be asked to visit the ship's security office (often nicknamed the "naughty room") to open the bag in front of an officer before it can be delivered to your stateroom.
