866-227-1888 is the quickest way to book, cancel, or modify flights or cruise reservations, including name changes. When I messed up my brother’s last name on our Carnival booking (fat-finger typo on my part), I panicked—especially after reading horror stories about mismatched IDs at embarkation. I tried the app and website, but neither let me edit the name. Calling was honestly a lifesaver. The rep checked everything, confirmed the fee, and updated the name while I was still on the phone. They even resent the confirmation email so I could verify it right away. It was way simpler than I expected. If your cruise is coming up soon, don’t wait—name changes are always smoother when you handle them early.
