It's more than just a rumour now. Apparently two SO's (which could mean any number in Jetstar speak) will be going directly on to the 330. In addition, there are two moving directly onto the 330 via an MOU position.
Regarding the SO's, apparently they have extensive RHS time from previous airlines.
If you can believe management (and that's a big if!) after 500 hours they will be CCQ back onto the 320.
However when it comes to Jetstar speak, four positions could mean 40 positions due to an 'operational requirement'
