If you have an American Express Membership Rewards account, you can transfer points to participating frequent travel programs, one program being your Marriott Bonvoy account. Usually one Membership Rewards point equals 1 Marriott Bonvoy point. So 1,000 American Express Membership Rewards points will yield 1,000 Marriott Bonvoy points.
However, now through 5/31/2022, you can receive 25% more Bonvoy points when you transfer Membership Rewards points to your Bonvoy account. So during this offer, 1,000 American Express Membership Rewards points will yield 1,250 points.
If you are trying to accumulate Marriott Bonvoy points right now, this may be something you may want to consider taking advantage of.
