I also think it will be a sandwich/wrap and maybe TV, thats about it. I think Virgin have gone off the ball with their PE strategy, its clearly not working and hasn't been working for some time. Atleast this will bring it a bit closer to par, but i think people will still prefer using QF.

Since the seats are underutilised, maybe they should do upgrades for FFers like Air NZ do now with their domestic Space +, which is economy seats with more room for their higher tier status flyers. That way they feel they are getting something more which isn't costing the airline anything more if the seats are empty. Infact it may open up more economy seats on peak/full flights. Overall it would help retain customers from going to/back and forth between QF.
