I was reading a blog about a person traveling that had his drone confiscated at the airport.
I have travel plans to Los Cabos, Mexico and to the Galapagos Islands soon.  Any issues or
restrictions that anyone knows about?  Probably take my Mavic insteat of Phantom 4 Pro.

The regulations are different in various countries. You may find more info from this post: https://forum.dji.com/thread-115947-1-1.html
