Lou scannon - I like a lot of what you say generally and in this case you've hit the nail on the head. I was ALWAYS the LAST off the aircraft - made sure all pax looked after and cabin crew off also. When it comes down to explaining chain of command to the CSD/purser I have NEVER had a problem there either. If they start being a bit arsy then I tell them straight, adding at the same time that they always have my FULL support and back-up with any problems they may encounter during the flight, and the first officers full support and back-up. Things have always worked smoothly thereafter.... It's not a big deal, just don't be afraid of the PC brigade and their "everyone is equal" claptrap.
For the record I have just left BA, where most of this PC rubbish happens and am now with an overseas airline that very definately teaches the correct chain of command to all CC. Very refreshing indeed.
