Some Amex cardholders are being targeted for a 30% bonus when transferring Membership Rewards points to Marriott. There is no listed end date on this deal, so transfer your points soon if you’re interested.We first spotted this offer on The Platinum Card® from American Express and The Business Platinum Card® from American Express, but other cards may well be targeted – check your accounts just in case.For more TPG news delivered each morning to your inbox, sign up for our daily newsletter.Amex points are typically transferred to Marriott Bonvoy at a 1:1 ratio. We value MR points at 2 cents each and Marriott at a mere 0.8 cents each, so this isn’t the best way to use your Amex points. But if you’re a few thousand points shy of your dream Marriott redemption, this could be the way to go.Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
