Talking to friends in the orange land I doubt they will be streaming people through quickly now as since nov last year they slowed their recruitment right down.
This was mostly due to too much expansion happening too fast which they can not manage, some A319's being delivered with faults and deciding to convert STN to 319 from their 737's.
As such , doubt they will be pulling people in from hold pools for six or seven months as training capaciy is full and then will be offered a European base.
I suspect with the orders you will be offered 319.
