I have yet to have an issue, mostly I am loyal to the Royal Caribbean. I have taken my drones all over. Some areas are more friendly than others, Cozumel comes to mind. Make sure you check with the locals.

Airplane, keep in carry-on is the best advice. Should not have any issues if you plan everything out in advance.

Make sure you have all your gear ready, so you don’t forget something on your way out the door.

A lot of the flying I do is for my job and everything has been easy enough so far.
