Four transfer bonuses are live in May 2026 — Chase→Marriott +55%, Chase→Southwest +30%, Chase→Flying Blue +20%, and Amex→Hilton +20%. Here's the honest math on which are worth it and which just flatter a weak points currency.
TL;DR
- Chase → Marriott Bonvoy: +55% — the biggest number on the board, but Marriott points are worth the least, so run the math before you move.
- Chase → Southwest: +30% — the rare bonus that's almost always a yes if you fly Southwest. (We broke this one down in full.)
- Chase → Air France/KLM Flying Blue: +20% — quietly the most useful of the four for actual award flights.
- Amex → Hilton Honors: +20% (through May 30, 2026), stacked on the standing 1:2 ratio, so 1,000 Amex points land as 2,400 Hilton. Cutoff is firm — verified 5/28 against americanexpress.com/rewards/transfer.
- The only rule that matters: a bonus is worth it when the destination points beat what you give up. A fat bonus into a weak program still loses to a no-bonus transfer to Hyatt.
A transfer bonus looks like free money. Move points you already have, get 20–55% more on the other side. Sometimes that's exactly true. Other times you're being nudged to dump flexible bank points into a currency worth half a cent. Here's what's live right now and where the math actually holds up.
| From | To | Bonus | 1,000 points becomes |
|---|---|---|---|
| Chase Ultimate Rewards | Marriott Bonvoy | +55% | 1,550 Bonvoy |
| Chase Ultimate Rewards | Southwest Rapid Rewards | +30% | 1,300 Rapid Rewards |
| Chase Ultimate Rewards | Flying Blue (Air France/KLM) | +20% | 1,200 Flying Blue |
| Amex Membership Rewards | Hilton Honors | +20% (ends 5/30/2026) | 2,400 Hilton |
Bank points (Chase, Amex) are flexible. Once you transfer them out, they're locked into one program. So the question is never "how big is the bonus?" It's "are the points I'm getting worth more than the points I'm spending?"
Hyatt is the cleanest example. There's no Hyatt bonus this month, yet a plain 1:1 Chase → Hyatt transfer still out-earns a +55% Chase → Marriott transfer for most hotel stays, because a Hyatt point simply buys more room. A bonus doesn't fix a weak currency.
Do transfer bonuses post instantly? The bonus points usually arrive with the transfer, but timing varies by program — confirm in your account before you move a large balance.
Should I transfer speculatively to grab the bonus? No. Transfer only when you have a booking in mind. Locked-in program points can devalue with no warning.
