Weird, I booked my current au-us trip booked on AA codeshares turned out to be around $300 less than the exact same flights on QF flight#.
Booked through b3stflights but a horrible experience - will never use them again.
I'm sure with all the aussie AA plats here there's some kind of demand for booking on codeshares
