Quite a few usually stationary things can get airborne in my sewing room especially when nagging and whining are introduced. Now seriously, I fly a lot and I am 100% sure that you can NOT have it in your carry on. Pack in in your checked luggage. It'll be fine. My dogs fly with me all the time, but once I was not even allowed to have their leashes with me. I had to go back to the counter and figure out how to get friggin leashes to my destination.
