Relatively complex question regarding FFP
So this summer, I took a RTW F OW trip with my family. We went ORD-LAX-SYD-BKK-HKG-LHR-ORD on AA, QF, CX, and BA. There were also 3 intr-Aus segments in J on QF, SYD-CNS-AYQ-SYD. The miles were supposed to go to BA but then they screwed us over and didn't give us elite status since we didn't have 4 segments (We would have but changed BKK-LHR on BA to BKK-HKG-LHR on CX because of their cancellations following the terror threats). I don't have a QF FFP account but am wondering if I open one, would I be able to transfer all these flights and if so, get elite status on QF? Also, would opening a USA account cost any money? Thanks for the help!
