Fiftyfour,
You're absolutely correct regarding the 'welcome' PA. We are required by our orders to include 'BA Operated...', 'Safety & Security', pay attention to safety briefing, seatbelt policy and welcome any OneWorld codeshare pax. The CSD/Purser is supposed to listen to what's been said so they don't repeat the info, but to be honest they are too busy during the boarding to listen to the PA and it is inevitable that stuff gets repeated. I feel sorry for the poor FOs who sit there with 1000 yard stares as Capt Speaking launches into the same diatribe for the 4th time that day; I'm half asleep or signing paperwork while I do it, so they must be sticking pens in their legs to stay awake.
Ahhhh, litigation, isn't it wonderful for improving everbodys lives
