OK, this is a rumour network right?
Try this one on for size. A yet to be announced delay in the B787 to J* (and everyone else) will mean J* is "forced" to take ALL the A330's from mainline to service it's expansion.
CCQ and all that.
Mainline gets ALL the B787's when they arrive. Already "Boeing" friendly outfit with experience on similar types.
Jetstar remains all Airbus/CCQ. A330/A320 and whatever else.(A380?)
I know "tell him he's dreamin".
Just a "rumour" I've heard.
