1. I was stopped in Canada. They had me take my machine OUT OF THE BAG.
2. Only CPAP machine is supposed to be in the bag. But I have included an extension cord.
3. I wonder what they do with the extra distilled water. Even for a 25 day cruise, I could not use it all. Felt sooooo wasteful.
4. If there is no room in the overhead for your CPAP, the flight attendants will find somewhere to store it. They know they can't have you check it (they don't want that responsibility).
5. I have taken overhead carry on, under the seat personal (big) item, and CPAP. I have been questioned at the gate, but then they step back when I say CPAP.
