Am looking at doing an ex-CAI RTW as I think its probably still the best place to buy them.

Routing will be as follows in A or D class

CAI-LHR-JFK-SFO-LAX-SYD- and its here I want to get from SYD to DME or SVO

I guess the normal route would be to come back to LHR and then do LHR-DME return before going back to CAI. The rules say I have 2 free segments within Origin continent and I am assuming that CAI-LHR and then LHR-CAI counts as these 2.

The other rule seems to say I can add segments for $200 USD per segment within a continent and therefore I assume I can add LHR-DME return as a side trip for $400 USD in D. This in theory is going backwards but as its within a continent I assume its allowed.

Therefore full trip ends up being

CAI-LHR-JFK-SFO-LAX-SYD-LHR-DME-LHR-CAI

This I figure is a AONE4 or a DONE4 with extra $400 USD for the DME side trip

Anyone disagree ?? or have any better ideas of how of may do this.

I guess I can get a few more exec points if I split the LHR-SYD as LHR-SIN-SYD

Have checked routing throuhg BKK, SIN, HKG, HEL but all involve non oneworld.

TIA
