I would like to ask another question on this string, if OP doesn't mind. (I have cruised with CPap and your suggestions seem spot on). We, however, usually drive to ports. This time we are flying and I have not flown with my CPap. Any hints on how you pack your CPap and how to get through security with it? I want it to be sanitary and to be as light weight packing as possible, without having to invest in a travel CPap. Have any of you used a special travel bag, etc?
