Remember Marion that at the altitudes you will fly, it is very DRY. Besides breakage and theft, I would also fear the neck warping or the belly splitting. It might be adequate to use a dampit. Perhaps someone else knows.

All I can say about the discount airline is, "cheap is cheap." Most airlines will at least allow you to put it in a cupboard in the passenger compartment if they don't allow you to put it overhead.
