Well that was BA's plan all along wasn't it?
Like they did with the cabin crew, bringing in the mixed fleet, they are doing the same with the pilots. Wanting a cheaper breed and putting them on a different pay scale to the one that the 'older' pilots are on. More pay scales means longer to reach the top pay point. Now that many pilots are working beyond 55, and many at a high, if not the top, pay point, its costing BA a fortune. Plus, i dont think the final salary pension scheme is on offer any longer as it was for many pilots.
The way of times.
