Anyone out there ever take your Voyager on a plane? I am planning to do so real soon...When it was time to choose, I regrettably opted for the soft-case...

Am considering getting the $249 ATA case, but w/ shipping to Hawaii its gonna be $350, and that is going to be a hefty expense right now...
Wondering if they'll let me take it on as a carry-on & stow it up top?
My Lady has suggested re-packing it in it's box and checking it in w/ my other bag(s)...but I'm worried about it getting abused like all the other luggage does...
If the ATA case is the way 2 go, I guess I gotta make some sacrifices, any experiences out there???
Thanks for any advice!
