what was the feedback on the unsuccessful calls?
I got dropped off twice whilst they put me on hold.
On the 3rd successful call, the agent actually suggested the direct NRT-TPE flight at first but I told him that I would prefer to travel in F so won't mind transiting in HKG. He just put that through without questioning.
The booking on USDM website actually looks quite clean as the agent grouped the HND-HKG-TPE as one group of booking under the same header, whilst he grouped the return HKG-NRT-SYD as another group.
I might just have been very lucky but the agents didn't really question the routing at all. The third agent put me on hold to get pricing at the end and he came back with 240k miles per px originally, but when I questioned and referred to the chart saying that it should be 120k each, he went away to check and came back confirming it is indeed 120k per px plus 499 tax in total for 2
