most of us if not all would expect in the captain is on-board (his intended PIC flight) he would have the ultimate say/control
Band a Lot, thanks, during the boarding and prior to door closure, I don't see why the pilots should be involved in what it is happening in the cabin. They have their own responsibilities preparing the aircraft for flight, data entry, performance calcs etc, etc. If it is deemed necessary to call upon the pilots, with stripes to reinforce a message at this stage of a trip, I think it points to an organisational failure. Surely the the senior cabin crew member would have the authority to deal with any issue in the cabin, without resorting to calling upon the services of pilots. Airborne a different matter.
