Transferring Amex Membership Rewards to KrisFlyer: the 3:1 rate, the two routes, and when the detour through Velocity wins
By Craig McNamara · Published on 26 July 2026
Amex Membership Rewards is the flexible-points currency behind the Amex cards I track, and Singapore Airlines KrisFlyer is arguably the best place to send points if a premium-cabin Singapore Airlines flight is the goal. But the transfer has a quirk most guides skip: there are two routes from Membership Rewards to KrisFlyer — direct, and via Velocity — and they don't cost the same or behave the same.
Here's how both work, the exact rates, and the traps.
The direct route: 3 Membership Rewards points = 1 KrisFlyer mile
The direct transfer rate is 3 Membership Rewards points to 1 KrisFlyer mile, with a minimum of 7,500 points per transfer. That's the rate on the consumer Ascent Premium program — the one attached to the Amex Platinum and the other Membership Rewards cards I track on the KrisFlyer credit cards page. You can always check the current rate on my points transfer page, which is the live version of everything in this post.
KrisFlyer survived the December 2025 Membership Rewards devaluation that hit several other airline partners, but 3:1 still puts KrisFlyer in the most expensive band of Amex's airline partners — the band several secondary partners were devalued into — while Velocity and Qantas (on the cards that have it) sit at 2:1. Whether it's worth 3:1 depends entirely on what you redeem for, which I get to below.
The mechanics, from Amex's own transfer FAQ and the Membership Rewards terms:
- Be a KrisFlyer member first — enrolment in the partner program is your responsibility, and you can only transfer into an account in your own name
- Log in to your Amex account and link your KrisFlyer membership
- Go to Explore Rewards → Ready to Redeem → Transfer Points to Partners
- Choose the amount — Amex's FAQ only says minimums "vary" by partner; for KrisFlyer it's the 7,500 points above
- Confirm — all transfers are final
On timing: transfers usually land quickly, but Amex's terms explicitly say they have "no control over and assume no responsibility for the speed at which" partner programs credit the miles. Don't transfer the night before you want to ticket an award.
The indirect route: Membership Rewards → Velocity → KrisFlyer
The same Amex points can take a detour:
| Leg | Rate | Minimum |
|---|---|---|
| Membership Rewards → KrisFlyer (direct) | 3 : 1 | 7,500 points |
| Membership Rewards → Velocity | 2 : 1 | 2,000 points |
| Velocity → KrisFlyer | 1.55 : 1 | 5,000 points |
Do the maths on the two-step: 2 Membership Rewards points buy 1 Velocity point, and 1.55 Velocity points buy 1 KrisFlyer mile, so the detour costs 3.1 Membership Rewards points per KrisFlyer mile — slightly worse than the direct 3:1. The Velocity→KrisFlyer rate and its 5,000-point minimum are confirmed on Velocity's Singapore Airlines partner page, which also notes those transfers can't be reversed.
So why would anyone take the detour? Two reasons:
- Transfer bonuses. Velocity runs card→Velocity transfer bonuses on a roughly semi-annual cadence. A 15–20% bonus on the Amex→Velocity leg drops the effective cost below the direct 3:1 route. I cover the timing in the Velocity to KrisFlyer guide.
- Optionality. Points parked in Velocity can become a Virgin Australia flight, a Singapore Airlines booking through Velocity, or KrisFlyer miles later. Points sent directly to KrisFlyer can only ever be KrisFlyer miles — and they start expiring (next section).
Without a bonus window, the direct route is marginally cheaper and one less hop. With one, the detour usually wins. The Amex to Velocity post covers that first leg in detail, and which bank points transfer where maps the full landscape if your points aren't with Amex.
The expiry asymmetry: transfer last, not first
This is the single most important thing about the whole exercise.
Membership Rewards points don't expire. Amex's terms state there's no expiry date for points as long as you hold the card, stay enrolled and keep the account in good standing.
KrisFlyer miles expire on a hard 3-year clock. Under the KrisFlyer terms and conditions, miles "expire after three years… on the last day of the equivalent month in which they were earned". Earning or spending more miles does not reset the clock on your existing balance, expiring miles can be extended once for a fee (six months for ordinary members), and only PPS Club members escape expiry entirely.
So a transfer converts a currency with no use-by date into one with a firm one. The pattern that follows from that: find the Singapore Airlines award you want first, then transfer, then ticket. Miles moved "to be ready" are miles on a countdown.
Two related traps from the same terms:
- Nothing is reversible. Amex says all transfers are final; Singapore Airlines says conversion transactions cannot be reversed. There's no undo anywhere in the chain.
- Cancelling the Amex ends the game. Under the Membership Rewards terms, cancelling your card forfeits any points still in the program (if another enrolled Amex account remains open, Amex may allow the points to be relinked — discretionary, not guaranteed). For churners, that means emptying the Membership Rewards balance — to KrisFlyer or anywhere else — is part of the cancellation checklist. My cancellation workflow covers the full sequence.
Why bother with KrisFlyer at all?
At 3 points per mile, KrisFlyer costs half again as much as Velocity or Qantas. It stays on my radar for one reason: Singapore Airlines premium cabins on their own aircraft.
Singapore Airlines releases award seats in its Suites, First and Business cabins to its own KrisFlyer members that partner programs either can't see or can't waitlist. Booking as a KrisFlyer member also gets you the longest booking window and access to Saver-level pricing on SQ metal. For long-haul Business or Suites out of Australia, the cents-per-point value of those redemptions is what makes an expensive transfer ratio tolerable — the same logic I worked through (with the award numbers) in the Velocity to KrisFlyer guide.
If your redemption is economy flights, gift cards or domestic travel, the 3:1 ratio is hard to justify against sending the same points to Velocity at 2:1. This is a program for a specific, premium use case — not a default destination.
The short version
- Direct rate: 3 Membership Rewards points = 1 KrisFlyer mile, 7,500-point minimum, own-name accounts only, transfers final.
- The Velocity detour costs 3.1:1 without a bonus — but during a card→Velocity transfer-bonus window it beats the direct route, and Velocity parking preserves optionality.
- Membership Rewards points never expire; KrisFlyer miles die at 3 years. Transfer when you're ready to book, not before.
- Empty the Membership Rewards balance before cancelling the card — points don't survive the account.
- Live rates for every route are on the points transfer page, and the cards that earn Membership Rewards are on the KrisFlyer cards page with current offers.
