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 lines perform thorough security screenings of all luggage in 2026, similar to airport security but with different priorities. Every piece of checked and carry-on baggage is passed through an X-ray scanner at the terminal. Security is primarily looking for prohibited items such as weapons, illegal drugs, and fire hazards (like irons or candles). However, a major focus for 2026 is the crackdown on unauthorized alcohol. If the X-ray reveals "mystery liquids" or bottles that look like liquor, security will flag the bag for a manual search. Many cruise lines have adopted a "Zero Tolerance" policy in 2026; if you are caught smuggling prohibited items, your bag will be held in a "naughty room" until you come to claim it, and some lines may even deny you boarding or issue a fine. For 2026 travelers, it is a high-value "pro-tip" to keep your medication and valuables in your carry-on, as checked bags can take several hours to reach your stateroom after the initial security sweep.
