The only reason people store so much hand luggage is that the airlines charge for checked baggage

I try to fly with only hand luggage even when checking in luggage is free since it makes the the check in process slightly faster, saves me having to spend half an hour waiting for my luggage at the other end, means I have my luggage if my connecting flight gets re-routed or cancelled and makes it much more unlikely that my luggage gets lost along the way.
