Sounds like an interesting rumour,
I think that the big problem BA will find is the required intake of high QUALITY candidates. Netjets, Flybe, Thomas Cook and Excel now get the pick of the best candidates through OAA, and through CTC the airlines associated with them get their pick, as with FTE.
With all the airlines wanting the best or a certain standard, the competition for the high end guys will be fierce, so if needs be, to attract a higher number of people to the industry that otherwise couldn't afford the training/otherwise put off, and therefore increase the chances of having enough people of the required standard, there may be a need for BA and other airlines to offer something.
Then again, being a legacy carrier they may not need to do the above as the airline is attractive enough, who knows, some people do, but the rest of us may only speculate.
