Qantas has specific planes for its LAX-SYD/MEL/AKL-LAX route. These have a little bit fewer seats for the long distance to make it just a little lighter. Of course, Qantas can change their setup and although these planes are used on this route 99% of the time, things change. But almost always, they use:
And of course, the ones with "VH-OJ*" are the ones with the GE engines, not the RB-211 engines with the single engine pod.
I'm not sure which ones have the PTV's but I'm guessing, by now, half or so have them. I think that ALL Qantas 744s should have the PTV's by July 2002... but I'm not sure of the date. Definitely by mid-2002 though.
Hope this helps.
