Thing is, not all the promos are listed on the website! A couple of years back, I I called in to book a ANZ card linked fare and invoke my seat guarantee (global reservations lines, not the SIN office). The agent couldn't find that fare, but, got me the exact same fare with UOB cards (something like 'aah found the $XXX fare..wait, its for UOB cards')- which worked even better for me (Ticket restrictions did have a 'must be paid with a UOB card' ..or something like that.
And the UOB fare wasn't listed on the CX site at that time.
