My understanding from reading the rules rather than having done this:

Gulf Air is not a member of Oneworld so you can't use them.

Qantas not QUantas!

1) Direct distance between two points.

2) No, but since LANChile is apparently far superior to AA why would you want to?

3) You can't do it - see above.

4) Yes-ish. You can't use Air Tahiti Nui on a OneWorldExplorer so can't get to Tahiti. And Nairobi-Delhi is still tricky: you would need to go NBO-JNB-HKG-DEL
