BA needs to find a way to drastically reduce the average age of their CC, not only will that mean younger and more eager to please CC but with the major reduction in seniority would also greatly reduce the wage bill.
Perhaps we could extend that to every industry? Lets kick out all the Senior Managers (Jaded, old, set in their ways) and replace them with much cheaper "fresh" Junior Managers, eager to please etc etc
I personally find the service from older Cabin Crew to be more courteous and respect flows both ways a lot easier. They are also on the whole somewhat more professional. You ain't seen those youngsters downroute after a few beers... it is NOT a pretty sight.
