I've finally got a good place holder DONE4 ex-JNB, question will be can I actually do all of it within a year!

JNB-DOH-MAD-HEL-DXB-LHR-LAX-DFW-YVR-JFK-SJU-ORD-HKG-CMB-NRT-HKG-JNB

Total BIS - 52,878

I hope to avoid BA fuel fines throughout using codeshares wherever possible (eg. DXB-LHR by connecting direct to LAX), although QR D availability JNB-DOH-MAD is a threat to that strategy.

Anything I should have considered to maximize?

Possible side trips (Avios//AA)
1. MAD-MXP
2. MAD-LHR
3. LHR-XXX
4. DXB-MCT//GOA
5. CMB-MLE
6. NRT-ICN
7. HKG-SGN//MNL
