There is NO way BA will pay for a cabin crew bidline system
All I have heard so far is negatives about giving cabin crew control of their lives and some job satisfaction. It can't work in BA etc. Well it seems to work very well in American airlines, perhaps just buying one of their systems off the shelf would be the way forward, not trying to re-invent the wheel and ending up with a square object.
We need to find some positives for all cabin crew and maybe an innovative rostering system for MF would be a start.
Think positive.
