although one agent told me on the phoen I need local card, it's not clear from T&C. This is phillipines, once you have ticket issued I don't see who will verify/deny you at check-in. Besides how do they know it's a PH issued CX amex from numbers alone?!?!

to me common sense tells me that I can show my CX elite card (issued in HK) and as long as numbers match they wouldn't care. You can always say "I didn't know" as tickets are issued under MY NAME MY CX CARD already.

last time I did this, I bot ticket but did online-check in for most journey and no one asked for my card.
