As for checked luggage, I suspect it's something they haven't thought through - no airport is going to allow passengers to mill around on the tarmac trying to put their luggage in the hold or waiting to get it at the other end. It's certain to b*gg*r up their schedules

Of course they could just force everyone to drop their bags into a standard luggage container and then deliver that to the plane
