Plodding Along
We have gone from 2000 to 500 crew on the proposed fleet for the time being. All new aircraft coming to BA will belong to this fleet which will be crewed by cabin crew on different contracts and working to scheme. Routes will be transferred to this fleet accordingly and present crew, on the "old fleet", will not be able to transfer unless they resign from their contract and accept the new one. Eventually there won't be any aircraft left in the old fleet.
That's their plan, I think.
