My main carry on is my Backpack camera case. In addition to my Dslr, lens and camera gear it also carries my laptop, meds and c-pap. Had I not got it back, I would have been very mad.
We boarded the plane on the run way, so we saw the case being put in the cargo hole, Since I was 3 off I also saw it being unloaded. Did I like turning it over no.
