frozenpilot,
The BA action dates back to Jan 2006, I'm not sure what the requirements would be for other companies but Jan 2006 is when the BACC submitted the initial claim.
As to 'how much' it would depend upon your companies pay structure. It's a very complex scenario as I'm sure you are aware as there are many poeople with differing pay scales.
The BA accomodation is an averaged one effectively so I would 'assume' that that will be the precedent taken forward.
