I've been searching to the answer for this, but to no avail. I would appreciate any advice from board members:

I'm looking to do a trip to MNL just after Xmas. I have an Amex 2-4-1 that will expire in Feb, so want to use it up (travelling J or F). Ideally I want to fly via HKG, but not fussy. At the moment, my available options look like they would involve an open jaw (possibly mixing F, J class) via SIN, PVG or even PEK returning via HKG. My question is: are any/all of those combinations possible? And where can I go to check which 'zone' a city is in for open-jaw purposes?

Back-up plan is to travel on paid WT+ to HKG and hope UUA availability opens up. Prices are good at the moment on the A380!

Thanks!

(at the moment I'm thinking of routing out via PEK, spending a couple of days there and then travelling paid (or possibly separate miles booking) CX PEK-HKG-MNL then MNL-HKG, stopover for couple of days there and then return to LHR)
