The campaign from Oct 2010 saw type streaming due to number requirements/training capacity. A few unrated guys went to the 744.
Not totally sure about the campaign ending in 2008, however i believe it was mostly shorthaul.
In 2005 quite a few went to the 777.
The FPP scheme ensures cadets are prioritised to shorthaul. BA pilots are entitled to bid across fleets after a number of years, however a bid doesn't guarantee acceptance. I suppose no one really knows what the fleet requirements will be going forward. It would depend on too many variables. It probably doesn't matter to most people attempting to join BA anyway
