Icarus, you reminded me of an amusing anecdote involving a certain Canadian carrier that shall rename nameless (the one with the shiny red engines). They had an A320 picking up 76 pax at YYZ, then the rest of the planeload at YUL before proceeding to someplace sunny. Some genius in passenger service figured that boarding would go a lot quicker if all the YYZ pax were seated in the back of the cabin
. Never did make it to YUL, as they left the APU exhaust pipe on the runway at YYZ.
