On this page
It depends on the partner. American Express UK shows its own estimated transfer time for each partner on the transfer page. For British Airways Club (Avios) and Virgin Points the estimate is 30 minutes, and Amex describes those transfers as instant. For others it's days: 4 working days for Flying Blue and Iberia, 5 for SAS, 15 for KrisFlyer. Hilton Honors shows an estimate of 20 days. If you're still inside the estimate, the transfer isn't late yet. If you're past it, contact Amex first with the date and amount, then the partner programme.

What we'd do first: open the transfer page, find your partner, and note the estimate shown there next to the date and time you made the transfer. That tells you whether you have a problem.
How long Amex UK says each transfer takes
These are the estimates on the American Express UK transfer page, read on 13 November 2026 at 21:29 Lima time (American Express UK: Transfer points, checked 13 Nov 2026, 21:29 Lima). They are Amex's published estimates, not guarantees, and they can change.
| Partner | Ratio (Membership Rewards → partner) | Amex's estimate | Amex's wording, where shown |
|---|---|---|---|
| British Airways Club (Avios) | 1,000 → 1,000 | 30 minutes | "instantly" |
| Virgin Atlantic Flying Club (Virgin Points) | 1:1 | 30 minutes | "instantly" |
| Delta SkyMiles | 1:1 | 30 minutes | "instantly… allow up to 48 hours" |
| ALL Accor | 300 → 100 | 30 minutes | "immediately but please allow up to 24 hours" |
| Marriott Bonvoy | 400 → 600 | 1 day | "within 1 working day of request" |
| Emirates Skywards | 1,000 → 500 | 48 hours | not shown |
| Qatar Airways Privilege Club | 500 → 500 | 48 hours | "instantly, but please allow 48 hours" |

| Singapore Airlines KrisFlyer | 900 → 600 | 15 days | "within 15 working days" |
| Hilton Honors | 200 → 400 | 20 days | not shown |
Three things to notice:
- "Days" often means working days. Where Amex gives a sentence, it usually says "working days". A transfer made on a Friday evening to Flying Blue could reasonably run into the following week.
- Hilton's estimate is long. The transfer page lists 20 days for Hilton Honors, with no sentence explaining it. If you plan to use Hilton points soon, treat this as the slowest partner on the list, and check before committing.
- Flying Blue limits how often you can transfer. Amex says "One transfer is permitted every 24 hours" to Flying Blue. Plan one transfer of the right amount, not several small ones.
For every partner, Amex adds: "once your points have been transferred, they cannot be transferred back." So the first rule is to be sure before you press the button.

Is my transfer actually late? A quick check
- Find the estimate. Use the table above, but check the live transfer page too, because Amex can change it.
- Count from when you submitted it. Write down the date and time. For estimates in days, count working days (Monday to Friday) and allow for bank holidays.
- Look in the right place. Points arrive in the partner account, not the Amex app. Sign in to the partner programme and check its activity or statement page, not just the headline balance, which some programmes update more slowly.
- Check the details. Amex will only transfer to a partner account in your name, and its Membership Rewards page says to "allow up to 14 days for us to verify your account" when you first link a programme (American Express UK: Membership Rewards, checked 13 Nov 2026, 21:30 Lima). If this was your first transfer to that partner, verification may be part of the wait. A name that doesn't match exactly, or a mistyped membership number, is a common reason transfers stall.
If you're still inside the estimate, wait. If you're past it, move to the next section.
What to do when it's past the estimate
Step 1: contact Amex. Amex is the one that sent the points, so it can tell you whether the transfer left your account and when. Its Membership Rewards page says you can "call the Membership Rewards team for free on 0800 917 8053 to transfer your points or link your details", and its customer service page offers chat: "Visit your Account and locate the chat icon in the bottom right corner" (American Express UK: Customer service, checked 13 Nov 2026, 21:30 Lima). Have ready:
- the date and time you made the transfer
- the number of Membership Rewards points and the partner
- the partner membership number you used
- whether this was your first transfer to that partner
Step 2: contact the partner. If Amex confirms the points left your account, ask the airline or hotel programme to look for an incoming credit under your membership number. Give them the date and amount Amex confirmed.
Step 3: keep a record. Note who you spoke to, when, and any reference. If the points never arrive, that record is what you'll need when you ask Amex to investigate or reverse its side.
We can't promise how long either side will take to fix a problem. Neither Amex's pages nor the partner pages we read set a timescale for investigations.

Protecting a reward seat while you wait
A delay hurts most when you've already found a seat. Points don't come back once they're sent, and a seat can go before they arrive. Some ways to lower the risk:
- Transfer only when you've found the seat. Search the partner's site first, with the exact dates, cabin and number of passengers, and note the price in points and the cash charges.
- Pick a fast partner where it makes sense. If the same seat can be booked through a partner with a 30-minute estimate (for example Avios through British Airways Club), that cuts the waiting time. Check that the price and charges are the same first.
- Ask about holds. Some programmes let you hold an award for a short time. Policies differ and change, so ask the programme directly rather than relying on a blog list.
- Don't transfer more than once to Flying Blue in 24 hours. Amex limits Flying Blue transfers to one every 24 hours, so work out the full amount first.
- Have a fallback. Know what you'll do if the seat goes: another date, another cabin, or paying cash.

A worked example (hypothetical)
This is a hypothetical example to show the timing, not a live price or a real booking.
You find two economy reward seats with Flying Blue for 30,000 miles per person, one way, plus £60 per person in taxes and charges (hypothetical). That's 60,000 miles and £120 for two.
- Points needed: Flying Blue transfers at 500 → 500, so you need 60,000 Membership Rewards points.
- Timing: you transfer at 7pm on a Monday. Amex's estimate is "within 4 working days", so the miles could arrive any time up to the end of Friday.
- The risk: the seats may not still be there on Friday. You can't move the miles back to Amex.
- The value check: at our assumed value of 1p per Membership Rewards point (an assumption, not a market price), the 60,000 points are worth £600, so the full cost is £600 + £120 = £720 for two, one way (hypothetical). If the cash fare for the same flights is lower, pay cash.
If on Friday evening the miles still haven't arrived, contact Amex first, then Flying Blue, as above.
Trade-offs
- Speed versus value. The fastest partner isn't always the cheapest for your trip. A slower partner with lower charges may be worth the wait if the seat looks safe.
- One large transfer versus several small ones. One transfer is simpler to track, and avoids the Flying Blue 24-hour limit, but it commits more points.
- Waiting versus chasing early. Chasing inside the estimate rarely helps. Chasing promptly once it's passed does.
If it still hasn't arrived
If both Amex and the partner say they can't find the transfer, ask Amex to open an investigation and give you a reference. Ask in writing (chat transcript or a written complaint) so you have a dated record. If you're unhappy with the outcome, Amex's UK customer service page links to its complaint-handling information.
Amex transfer delays: FAQs
Can I cancel a transfer that hasn't arrived?
Amex says transferred points "cannot be transferred back". Ask Amex whether a pending transfer can be stopped, but don't count on it.
Why is Hilton so slow?
Amex's page doesn't say. The estimate shown is 20 days. Plan around it.
Do I need to link the partner account first?
Yes. You can link it online or by phone, and Amex says to allow up to 14 days to verify it.
