I just returned from a Carnival cruise to the Dominican Republic, St. Thomas, Puerto Rico, and Grand Turk. I had the Mavic fly more combo and accessories in a backpack. No problems getting through the airports. Upon boarding the ship, I sent my backpack through the x-ray and the security person grabbed it as it came out the other end and ran it back through. It came out and I picked it up and proceeded on my way. It went with me at every port of call and was x-rayed upon re-boarding each time without incident. No problems at all. The beach at Puerto Rico was close to the airport and the Mavic controller said NFZ Limit but let me fly anyway.
