Hello all -
Apologies if this has been posted already. I tried doing a search, but to no avail. I have a partly used oneworld Explorer 5 continent ticket. I have used SYD-LHR (note: no stopover in Asia at this point)
and have unused coupons for travel as follows:
LHR-LAX-SJO-DFW-SCL-LAX (transit without stopover) -SYD

I am trying to change the dates of my return to SYD and am having a devil of a time finding availability for LAX-SYD in January - not a big surprise considering how close it it! However, I am wondering if would be possible for me to use the rule permitting one to travel through Asia twice if one is a transit without a stopover between SW Pacific and Europe. My outbound flight to Europe was on a direct QF flight that transited in SIN, but same flight number and no stopover taken in Asia. So, could I fly SCL-LAX (transit without stopover) - HKG -SYD where there seems to be ample availability?

Thanks for any and all help!
