I am new to the Mavic Pro and this forum.  I am getting ready to take a trip out of the US and wondering if anyone can give me a few tips on flying with my Mavic. I already have a pelican case for it, and plan on having it as a carry on.   Thanks

Make sure you check the airline you use what their rules are concerning Lipo's.
There are special bags for them, but not all airlines allow to take them with you.

Basically, it might not have issues to take the drone to the airplane, but like Montfrooij mentioned above, you can check the specific details with the airline company, thank you.
