Can Amex offers be used by Amex cardholders whose cards are not issued directly by Amex, but which are still on the Amex network? (i.e., Amex cards from FNBO, other lenders)
Galahad - No, the card has to be an Amex issues Amex card to get the offers
Actually, sometimes yes.
If the offer is available via the Twitter or Facebook channels, it can be added to a non-Centurion Amex card. Admittedly, though, the offers available like this are limited and many times the 'really good ones' are for Centurion Bank ("real" Amex) customers only.
