Whilst they are sourcing future 787 crew from the 320
Thats not completely correct.. first bunch of B787 crew come from the B777 fleet and sometime after the 3rd B787 arrival there will be some movement on the A320 to the B787. not as many as some tend to think / hope, thereafter it will be combined with Direct Entry pilots. In typical airline fashion the Direct entires will exceed the number of transfers.. same same as usual, no different.
