Amex has tweaked its Membership Rewards transfer ratios to hotel partners, and the math just got a bit uglier for anyone chasing luxury redemptions at Hilton and Marriott properties.

The changes rolled out quietly this summer, with the most noticeable hit to the effective cost of certain stays. While the base ratios didn't flip dramatically across the board, the removal of habitual transfer bonuses and a slight adjustment in how points flow to Hilton Honors means your Platinum and Gold card points aren't stretching as far for those fifth-night-free or SLH escapes.[[1]](https://travelingformiles.com/amex-membership-rewards-transfer-partners-transfer-times/)[[2]](https://x.com/asktarunn?lang=en)

Let's cut to the specifics. Amex to Hilton Honors remains listed at 1,000 MR = 2,000 Honors points. That sounds generous until you remember it used to pair reliably with 20-50% transfer bonuses that pushed it to 2.4:1 or better. Those promotions have dried up. The result? A de facto devaluation that @asktarunn highlighted perfectly: what was once a 15,000-point SLH night now effectively costs closer to 10,000 MR under the old bonus math, but without the bonus it's back to 7,500 MR for the same award — still decent, yet no longer the screaming deal it was.[[2]](https://x.com/asktarunn?lang=en)[[3]](https://onemileatatime.com/deals/amex-hilton-transfer-bonus/)

Marriott Bonvoy took a similar haircut in perception. The standard ratio sits at 1,000 MR = 1,000 Bonvoy points (or 5:6 in some markets, netting 1.2 Bonvoy per MR). With fewer targeted bonuses this year, luxury brands like St. Regis or Ritz-Carlton that used to pencil out at 1.5-2.0 cents per point now hover closer to break-even after dynamic pricing and resort fees. If your go-to redemption was a 35,000-point peak night in the Maldives, you're now looking at 35,000 MR for something that might cash for $600. Not terrible, but not the flex it once was.[[4]](https://pointsmilesandbling.com/amex-mr-to-marriott-bonvoy-30-transfer-bonus/)

The SLH Sweet Spot: Still Viable, Barely

That 10k MR/night claim from @asktarunn's post? It was predicated on a 20% or higher bonus layering on the 1:2 base. Without it, you're looking at 7,500 MR for a 15k Honors night. For true luxury SLH properties in Europe or the Caribbean that would run $800-$1,200 cash, it still works out to 1.0-1.6 cents per MR. Respectable, but only if you have a specific booking locked in before Honors changes its award chart again.[[2]](https://x.com/asktarunn?lang=en)

Marriott luxury brands are in rougher shape. The 5th night free still helps on longer stays, but dynamic pricing means peak awards at Edition or Luxury Collection can spike to 60k+ points. Transferring 60k MR for a $900 room isn't the victory lap most points nerds are chasing. Hold unless you see sub-40k opportunities.[[5]](https://www.nerdwallet.com/travel/learn/the-best-amex-transfer-partners-and-ones-to-avoid)

Airline Partners Largely Spared

Good news on the flying side: Virgin Atlantic Flying Club stayed at a clean 1:1. No quiet devaluation there, unlike the earlier hits to Emirates and Cathay Pacific ratios earlier in the year. If you're eyeing Delta or ANA redemptions via Virgin, your MR points retain their punch. The real drama this week was confined to the hotel side.[[1]](https://travelingformiles.com/amex-membership-rewards-transfer-partners-transfer-times/)

Chase and Citi Alternatives

Here's where it gets opinionated. Chase Ultimate Rewards still transfers to Hilton at 1:1 — meaning 1 Chase point = 1 Hilton point. That's materially better than Amex's 1:2 in raw efficiency, especially if you value UR points highly for Hyatt. Citi ThankYou Points also go 1:1 to Hilton. If you have a healthy stash in either program, route hotel stays through them and keep your MR for airlines or the new Leading Hotels of the World partnership (4:1 but with legitimate 2+ cpp potential on boutique luxury).[[6]](https://www.nerdwallet.com/travel/learn/airline-and-hotel-transfer-partners-chase-ultimate-rewards-vs-american-express-membership-rewards)

Amex's quiet shift isn't catastrophic, but it's the kind of death-by-a-thousand-cuts move that erodes trust. Hotel points programs are already inflationary nightmares. Making transfers less attractive just accelerates the "cash is king" mindset for high-end travel.

Action item: Audit your upcoming Hilton and Marriott stays today. If an SLH or luxury redemption pencils at 1.2+ cents per MR without a bonus, transfer the exact amount needed right now — points don't earn interest in your account. For everything else, leave the MR where they are and route through Chase or Citi instead. The window for these redemptions is closing faster than Amex announces the next "surprise" tweak.
