!!!!su_Tonka,
can't say what happens when it is used AKL-LAX as I have not operated this sector with the 300 but rammel is AKL based so he/she ought to know.
I do know for sure however that when it was used on the SYD-BOM sector it returned with the operating aircraft as it was needed outbound again.
It was always turned around so as to be inaccessable on the return leg which was "only" around 13 hours and outside our requirement for horizontal crew rest.
Flight attendant fatigue is a concept that has no bearing in qantas's present operation.
A cursory look at what we are being planned to do these days if proof enough of that.
How does PER-SYD red eye, transit SYD 3.40 operate SYD-DRW grab you???
Geoff Dixon aka "Dear Leader" is on record as confirming that as flight attendants we will have jobs in a few years time.
He suggested however that we won't like them.
