Two suggestions.
1--check it. I bought a 4in OD PVC pipe, cut it to fit, put a cap on one end and a screw fitting on the other. Sent it along with my other bags.
2--this one is more risky. Planes have coat closets on them. Ask that you place your stand in the coat closet. If they will not let you then you will have to check it with no protection.
