Agreed with the above - the routing is only valid if one of SYD-...-SCL or SCL-...-LHR consists of transits without stopovers in the US.

Also be aware that you have a lot of flights with no F so it seems a bit of a waste of an AONE6.
(SYD-HNL, LHR-IST-LHR, HKG-DPS-HKG, JNB-HKG unless Nov-Jan; all the AA 2-class domestics would get F on a DONE6)
