Brief to cabin crew (purser or supervisor):
Flight time to destination is ____, weather enroute expected is ____, if you have ANY problems that I can assist with, give a call on the interphone or visit up front personally.
Has worked for me for a very long time.
Those cockpit crew who constantly poke their noses in the cabin, are not attending to duties up front. Likewise for cabin crew.
If cabin crew want to be pilots, then go get the necessary ratings and apply accordingly.
Quite simple really.
