... The big drawback of the AA program is the lack of any codeshares on flights to/from SWP/Asia/Europe. Once upon a time, AA announced it was going to codeshare on the BA flights to Asia/SWP but it never happened. Currently, AY codeshares on CX and AY flights via HEL are probably the best options for getting 100% miles on discount economy tickets to/from SWP/Asia/Europe ... unless you have other suggestions?
BA now fully credits (almost?) all fare classes to AA, so that means the BA code shares on the QF flights would earn full credit. There are quite a few classes that do not earn full EQP. In my case, it seems that BA is continuing to code share on QF flights SIN-PER after 31 Mar - but only in economy
The main connecting points in SEAsia to Australia seem to be covered and seem to be salable without the LHR-SEAsia segments. Though CX shares to AKL do seem to need the connecting flight.
Happy wandering
