I normally check my bag, but on an upcoming trip to South Africa, with a brand new 22" Pathfinder (I won with Best Letter to one of those frequent business travel magazines), I'd like to keep it pristine for a few more trips. So where is the storage for carry-ons when flying CW on the upper deck of a 744? There are no overheads and from photos that I can see, the usual side bins are absent too. So not sure where I'd stow it up there?
