Its actually the Qantas A330's on loan to JQ that are returning to Qantas.
Due to the Qantas purchased B787's being deployed at Jetstar replacing the loaned Qantas A330's.
As the Qantas A330's return to Qantas, it allows the retirement of the Qantas 767.
This enables the Qantas guys and girls with 20 plus years widebody Boeing time to be redeployed & retrained to Airbus some electing to so voluntarily some forced.
Meanwhile the Airbus experienced guys and girls at Jetstar will be retrained to fly the Boeing 787.
But all will work out ok. Cause if Qantas order the B787 to be delivered to mainline in 2016. The guys redeployed to the Airbus A380 as Second Officers will be able to return to the B787 as FO's.
