Amex to Avios,
the smart way.
Membership Rewards move to Avios at 1:1, usually within a day. Here's the ratio, the timing, and how to let a transfer bonus do the heavy lifting.
American Express Membership Rewards points transfer to Avios at 1:1, so 10,000 points become 10,000 Avios. Transfers are usually instant once your Avios account is linked, though Amex asks you to allow up to 72 hours. Periodic transfer bonuses of roughly 15 to 30 per cent are the easiest way to boost the rate.
- One Membership Rewards point transfers to one Avios.
- Transfers are usually instant once linked, but American Express asks you to allow up to 72 hours.
- A transfer is one-way and cannot be reversed.
- Periodic bonuses of roughly 15–30% turn the same points into more Avios.
- Transfer against a specific booking, not on spec.
The same points, worth more.
A 1:1 transfer is fine; a 1:1 transfer during a 30% bonus is a bargain. The trick is knowing a bonus is running before you move points — miss the window and you leave Avios on the table. Nanvero watches transfer bonuses for the programs you hold, so the right moment finds you.

What is the Amex to Avios transfer rate?
American Express Membership Rewards points transfer to Avios at 1:1 — one Amex point becomes one Avios — so 10,000 Membership Rewards points become 10,000 Avios. Transfers are usually instant once you have linked your Avios account, but American Express asks you to allow up to 72 hours — so never transfer against a seat you have not already held. American Express also runs periodic transfer bonuses, commonly around 15–30% extra, and moving points during one of those windows is the single easiest way to boost your Avios. Because Amex points are flexible, the advice is to transfer only when you have an Avios redemption in mind rather than speculatively.
Enter the Membership Rewards points you would move, and a bonus if one is running.
10,000 Membership Rewards points become 10,000 Avios at the standard 1:1 rate. Transfers are one-way, so move points against a seat you have already found.
What a transfer bonus adds
The ratio never changes; a bonus adds a percentage on top for a limited window. Across a real balance that percentage is not small: a 30% bonus on 50,000 points is 15,000 extra Avios, worth about £150 at the typical 1p an Avios is worth on a reward booking.
| Amex points | At 1:1 | +15% bonus | +20% bonus | +30% bonus |
|---|---|---|---|---|
| 10,000 | 10,000 Avios | 11,500 Avios | 12,000 Avios | 13,000 Avios |
| 25,000 | 25,000 Avios | 28,750 Avios | 30,000 Avios | 32,500 Avios |
| 50,000 | 50,000 Avios | 57,500 Avios | 60,000 Avios | 65,000 Avios |
| 100,000 | 100,000 Avios | 115,000 Avios | 120,000 Avios | 130,000 Avios |
When should you transfer?
Transfer against a specific booking, not on spec. Membership Rewards points are flexible and a transfer to Avios is one-way, so points moved early give up their options for nothing — and because American Express asks you to allow up to 72 hours, hold the seat first where the airline lets you.
Within that, wait for a bonus if one is likely. A 1:1 transfer is fine; a 1:1 transfer during a 30% bonus is a bargain, and missing the window simply leaves Avios on the table.
- 1 Amex point becomes 1 Avios, usually within a day.
- Transfer bonuses of roughly 15–30% appear periodically.
- Transfers are one-way, so move with a plan.
Deciding whether to move the points at all? Avios vs Membership Rewards sets the two side by side.
Amex to Avios — common questions
10,000 Avios, at the standard 1:1 rate — one Membership Rewards point transfers to one Avios. During a transfer bonus of, say, 20%, the same 10,000 Amex points would become 12,000 Avios.
Usually within a day, and often much faster — many transfers land within minutes or a few hours. Transfers are one-way and cannot be reversed, so only move the points you intend to use.
From time to time American Express offers a bonus on points transferred to Avios — commonly in the region of 15–30% extra — for a limited window. If you transfer 10,000 points during a 30% bonus you receive 13,000 Avios instead of 10,000. Timing a transfer to a bonus meaningfully improves the value you get.
It can be very worth it, especially into premium-cabin flights and during a transfer bonus, because Avios often redeem for more than the value Amex assigns to a points-for-cash redemption. But Membership Rewards points are flexible and transfers are irreversible, so transfer only when you have a specific Avios booking in view — not on spec.
Nanvero surfaces transfer bonuses and opportunities that apply to the programs you actually hold, and keeps your Avios balance current automatically so you can see the effect of a transfer straight away. With the Playbook you can plan a specific redemption and see how a transfer closes the gap. Free to track up to five programs; the Playbook is part of Pro.
The 1:1 ratio and the 72-hour timing are American Express’s published transfer terms, as reported by the source below and dated when it was checked. The bonus table and the calculator are plain arithmetic on that ratio: they show what a bonus would add, not that one is running. Avios values use the same typical rate as What are Avios worth?.
Where these numbers come from: AwardWallet 1:1 standard ratio; transfers usually immediate but up to 72 hours; a 30% bonus for US cardmembers running to 27 September 2026 (September 2026). Transfer bonuses are temporary and ratios can change; check the live offer before moving points.
Nectar to Avios converter
Nectar and Avios convert in fixed blocks: 400 Nectar points become 250 Avios, and 250 Avios become 300 Nectar. The rate is not symmetrical, so converting back and forth loses value each time. The converter runs both directions in those set blocks and shows what any balance becomes.
Amex transfer partners
US American Express Membership Rewards points transfer to 16 airlines and 4 hotel programs. Most airlines, including Delta, British Airways, Air Canada Aeroplan and Flying Blue, are 1:1; Cathay Pacific, Emirates and JetBlue are 5:4, Aeromexico 1:1.6 and Hilton 1:2. UK Membership Rewards has its own list, with Emirates at 2:1 and Marriott at 2:3.
Avios vs Amex Membership Rewards
Hold Membership Rewards until you have an Avios booking in mind. Amex points transfer to Avios at 1:1 and never expire while you keep an MR-earning Card, so they are the flexible form of the same value. Avios lapse after 36 months of inactivity and can only be spent in Avios programs.
