Interesting routing .... presumably you really wanted to visit these cities and none of this is a mileage run (as an aside all but 2 of your sectors are optimized for the most uncomfortable business class flights on OW ... so at the end of your trip please don't blame Oneworld, most OW flights are more comfortable than your choices in terms of equipment and service). Probably QF is your best choice in FF plan, but it really depends on objectives and future travel. AA tends to be the best value (benefit per mile flown). AY also has some good points, esp. if you will fly AY periodically. So you should research AA/AY/BA/QF and pick from those, the other OW plans are generally (much) less desirable -- but each plan has something that it is uniquely good at. I went through the same process a couple of years ago (when switching to OW) and wound up picking AA as primary, QF as secondary and BA as overflow.
