So what do most airlines say about a backpack as baggage. I know the issue about gas canisters they won't even accept the stove head if it has been used. I'm concerned about the straps and such, particularly if the shoulder straps are not allowed. Also any chance the shoulder straps etc. could get caught in their equipment and tear up the pack. It would be easy enough to make a cloth bag to put the pack in, like a giant stuff sack, then mail it home. My shoulder straps can be removed, and the hip belt can be cinched flat.
Your experiences please.
