Chase Ultimate Rewards is offering a 65% transfer bonus to Marriott Bonvoy. The standard transfer ratio is 1:1, so with the bonus you’ll receive 1,650 Marriott points for every 1,000 Chase points transferred. The 65% bonus runs through May 15, 2026, after which a 55% bonus will be available through June 30, 2026, yielding 1,550 Marriott points per 1,000 transferred. We generally don’t recommend transferring Ultimate Rewards points to Marriott, even with this elevated bonus, as Chase offers several more valuable transfer partners.
