On second thought- it's probably less of a hassle to just check it. If it breaks, UA can pay for it (i hope... well, i really hope it doesn't come to that).
UA makes pax sign a limited liability release form when a box is checked.
So, is the box equal to or smaller than UA's specified 9" x 14" x 22" for carry-on bags?
