I have flown with 4v's many times! the absolute safest way to go is to just keep them in the schoeps plastic containers they came in. Its not that big of a deal to screw them on once you arrive at your destination. Now that being said, I have flown with them still on the active cables because I was lazy and just left them in their windscreens. If you have a nice bag, everything should be protected. Just place it in the overhead bin in a way it cant be moved around. good luck and safe travels
