With abit of luck you may fly on a new 744ER. QF will have 4 in service by the time of your trip. They are using these on the SYD & MEL to LAX runs.

If not you should get one of the newly refurbished 744's with the new IFE and decor.

However there will still be approx 3-4 744's out of the fleet of 28 which will not have had the upgrade. Hope you don't get one.
