Thanks for the prompt feedback.

I suppose paying for the PEK and PVG portions may make some sense. Spring Air might offer a way to do those on a LCC or we could do actual surface travel from HKG.

Could we then try:

nrt-hkg-bom-bkk, sin-per-syd-akl-ppt-ipc-scl-lim-gru-eze-lhr-cai-lhr-nbo, jnb-xhkg-nrt?

I'm a bit baffled as to how to fit in ipc when heading east so i am not sure this works.
