I've heard if you take away your CX FF# on which your upgrade was based on from the flight, they will have to rescind the upgrade. Don't know how that happens at T-45min when manifest is ready to 'downgrade' you back to a full J cabin.

But they will probably threaten it so most guys will say "ok I keep my CX FF#". In reality changing manifest after T-40 is much harder than changing your FFP number.

just make sure if you change your FFP number, to get a new boarding pass printed WITH the AA#, if not they will insist they never had you AA# afterwards and miles go to CX account.
