I think you'll find BAs cabin crew don't dump the rubbish as they don't clean the aircraft. Nor do the cleaners dump the rubbish as that comes off in sacks and goes down the engineering steps or rear steps to be disposed of at ground level, not on the jetty. I think frangatang refers to the general filth of discarded newspapers, food, boarding cards and all the other detritus Joe Pax discards. But thanks for the slating anyway.
