Do a search. Plenty on this topic. That said, I travel every other week for work (and once a month for recreation). The ONLY time I was stopped in an airport was last week in Long Beach, CA. TSA asked what was in my bag as they pointed to an object on the x-ray (or whatever you call it). I told them it was my mavic pro drone. They asked me to pull it out because they didn't want to damage it themselves. I pulled it out, they swiped it with a paper, and they proceeded to ask too many questions for their own personal knowledge..."oh, so cool, what brand, how does it fly, etc".
Been to Thailand, Hong Kong, and about 10 US states in the last 2 months, including Florida...never an issue with having my drone in carry-on bag. Do not put mavic pro in a checked bag unless you take out the battery. Lithium ion batteries can not go on checked bags.
Best of luck.
