Check each country before your trip because there are some that do not allow drones. In Morocco, for example, I had to leave my drone at the airport. You get a voucher and then pick it up when you leave. I got mine back without a problem.

Besides that I've never had a single issue bringing my drone on any flight or crossing any border. I also carry my DJI Mini 4 Pro with me, and I've also brought my Avata 2 with me as well.
