If the wifey and myself want to do a trip over the ditch to Oz I'm stuck as to how to achieve the following using the online booking system. I want the works - movies & food. She isn't bothered about that, is happy with an economy seat with carry on only but has asked if I can get the neighbour free guarantee on my ticket that she can then get the benefit of.

So i was thinking I could grab works deluxe - 2 carry ons and a neighbour free seat - sit in seat c. That would leave seat b free and she could then grab seat a with an economy ticket.

Would we have to undertake 2 different sets of bookings to achieve this ? Is it indeed possible or do they keep works deluxe passengers in a different zone on the plane ?

Cheers for your thoughts.
