Flying Tin Cans,
If you see my earlier figures they are based on a £750 pa difference. I agree that in year 1 £750 is not the end of the world. But this difference keeps increasing by £750 pa so by year 24 when the A scale has reached the maximum pay point the B scaler is on £17000 less pa.
Over the course of 34 years if you stayed a FO the B scale will earn approx £280000 less than on the A scale. Obviously no-one stays an FO for 34 years but this discrepancy is only magnified on the Captains payscale.
Regards
