My husband wants to travel to Denver in June. I have never traveled with the vest. I have always taken my flutter. Well, I don't have that "lung function" luxury anymore. I have a small portable vest with a travel case; but, how the heck to you take it on the plane. I sure as heck am not going to check the bag and If I carry it on they will probably make me tag it and put it with the luggage to get when I get off the plane. I would have to have it with me all the time to feel secure that it would not get damaged. I think it is too big to store in an overhead commpartment. How on earth do you guys do this?
