A Quick Look at Marriott Bonvoy Co-Branded Card Point Bonus Issues: What Can Consumers Do?
Basically, our top piece of advice is this: if you're charging your Marriott stays to an American Express Marriott Bonvoy co-branded card, always double-check that the bonus point multiplier on your final statement is calculated correctly. Sometimes, even though you clearly spent money inside a Marriott hotel, the Canadian Amex Marriott Bonvoy card only awards the basic 2x multiplier — not the 5x bonus points you'd normally expect when staying at a Marriott International property.
