The question could have been asked a little better so as to clear up the thread a bit I think you will find that the question that twiggs was asking referred to Cabin Crew slipping.
I sincerely doubt that the A330 tech crew or any tech crew would operate LAX/JFK/LAX ...I don't see the company giving the same to Cabin Crew.
My question is though, if they do operate the 330 on the AKL/LAX/AKL runs are they running out of 747's or are the loads that light....???
