Transfer Amex Membership Rewards to Marriott Bonvoy
The live transfer ratio is 1:1. Right now there's a +35% bonus running through May 10, 2026.
Amex to Marriott transfers at a 1:1.2 base ratio, and the 35% bonus brings it to 1:1.62 — so 50,000 Amex points become 81,000 Marriott points. That is enough for 1-2 nights at a mid-tier Marriott property. Marriott points can also be converted onward to 40+ airline programs at 3:1 (with a 5,000-mile bonus per 60,000), but this double conversion is only worthwhile if you need to top off a specific airline balance. This bonus size is moderate and appears a couple of times per year.
