T to B, you are dredging the bottom of the rumour barrell now. There are 2 mainline A332's in domestic config (which is identical to JQ config ie JQ Star Class is domestic business class seats) which are probably going to be given to JQ. The other 4 mainline A332's and all 10 A333's have mainline international configurations and thus would require an expensive conversion to the JQ configuration.
However, it's possible that Joyce may have finally woken up to what a lot of contributors on PPRuNe have been saying for a long time - Why not leave Jetstar as a pure Airbus operator & thus benefit from the CCQ savings? The A332's have the range to operate the routes that Jetstar international want to operate (ie SIN-FCO, SIN-ATH etc) so it would make sense to operate a fleet of A320's & A330's. The rumours to the effect that Joyce wants to cancel the first 15 B787's (the -8 variant) would confirm that this may be what Joyce wants to do. It would save a lot of retraining.
