Hi Og,
Thanks a lot for the reply. I've tried quite a few dates for the AKL-SCL leg but still having no luck - perhaps I'll have to take book the extra segment via Sydney and then re-book direct with Qantas for the AKL-SCL flight (hopefully!)
Thanks for the segment advice - I'm assuming then that your segments start once your in the continent (i.e. AKL-SCL wouldn't count as a S.America segment but SCL-GIG would be? )
I think I might contact an agent just to see what they think, thanks again for your help
