I have an Aerox portable system that we use in our Warrior. I don't use it as often as I'd like, mostly because it is a pain to install the Aerox seatback bag/strap setup. I don't like to leave it in the plane when not in use, plus it blocks access to the seatback pocket. Does anyone have any good solutions they've found for an alternative bag or securing option for a small oxygen bottle which is easier to take in and out?
