Whichever way you do the maths then the previously estimated recruitment requirements that BA had remain unchanged.
In my opinion those looking for evidence of this need look no further than this thread, which has seen reports of both 737 and 767 courses being offered yesterday, the very day the potential sale was announced, with one poster having it suggested to him that Airbus courses could happen in Feb.
I don't see the reason for the pessimism personally. A long wait in the holding pool is normal, as is seeing people fished out ahead of you since BA must match people to types as cost effectively as possible. It ain't pleasant but it's understandable and necessary.
