- The bonus: Amex Membership Rewards transfers to Avios at 1:1.3 from August 3 through September 27, 2026. 1,000 points become 1,300 Avios.
- The trap: moving Avios to British Airways for a long-haul flight on BA metal can cost several hundred dollars each way in carrier-imposed surcharges — often well over $1,000 round-trip in business. The Avios is cheap; the ticket isn't.
- Where it wins: off-peak Europe from 4,000 Avios one-way, Iberia's own transatlantic metal (surcharges a fraction of BA's), and partner flights on American and Alaska, which add no fuel surcharges.
- One currency: Avios is shared across British Airways, Iberia and Aer Lingus — you can move it between them, so the program you transfer to first isn't a lock-in.
- Our rule: only transfer with a specific award in mind. Amex-to-Avios is one-way and instant — speculative transfers are how people get stranded after a devaluation.
Every August this hobby runs on the same rhythm: a transfer bonus lands, seven blogs publish "transfer your points now" within about forty minutes of each other, and almost none of them tell you the part that actually decides whether it was a good idea.
Here's the news. From August 3 through September 27, 2026, American Express is running a 30% transfer bonus to Avios. Send 1,000 Membership Rewards points and you get 1,300 Avios. It's a real, meaningful bonus — one of the better Amex offers of the year — and if you have a redemption lined up, you should take it.
But "Avios" is not the same thing as "British Airways," and the difference is where most of the value in this offer lives. Below is what the bonus is, the single most common way people torch it, and the redemptions where 1,300 Avios buys a flight worth several times what the points cost.
What the Bonus Actually Is
The mechanics are simple. Through the offer window, U.S. Amex cardholders transferring Membership Rewards to Avios get a 30% bump, so the rate moves from the standard 1:1 to 1:1.3. Transfers post in increments of 1,000 points, and they're typically instant. The bonus is confirmed and dated by the coverage tracking it — One Mile at a Time and The Points Guy's running transfer-bonus list both put the window at August 3 to September 27.
The detail worth internalizing: the bonus applies to Avios, not to a single airline. Amex lets you send Membership Rewards to British Airways Club, Iberia Plus and Aer Lingus AerClub, and all three are denominated in the same Avios. So the "30% to British Airways" headline you'll see everywhere is technically true and practically misleading — you're really getting 30% more of a currency that three airlines share.
If you're new to how transferable currencies like Membership Rewards work in the first place — and why keeping points flexible until you need them beats hoarding a single airline's miles — that's the whole argument in transferable points vs. airline miles. This bonus is a textbook case of the principle: the points are only worth moving when you know exactly what they'll become.
The British Airways Trap Everyone Walks Into
Here's the part the "transfer now" posts tend to bury. British Airways passes carrier-imposed surcharges onto award tickets on its own long-haul flights, and they are not small — they can run several hundred dollars each way and push a round-trip business-class award to London well over $1,000 in cash fees on top of the Avios. And they keep climbing: British Airways has now devalued Avios twice in eighteen months, in July 2024 and again on December 15, 2025, raising both the Avios required and the cash surcharges attached.
So picture the move most people make with a fresh 30% bonus: they transfer a big chunk of Membership Rewards to British Airways, book a long-haul BA flight in business, and then get to the payment screen and pay four figures in "taxes and fees." The Avios were nearly free. The ticket was not. You've converted flexible Amex points into a currency locked to an airline that then charges you most of the cash cost of the seat anyway.
The Avios is cheap. The British Airways long-haul ticket isn't. Almost every good use of this bonus is a plan to route around that surcharge.
This is the competitor delta on this offer, stated plainly: most guides treat "Amex 30% to Avios" as a prompt to feed British Airways. The reality is that the best uses of Avios deliberately route around BA's own metal — because Avios also books partner airlines that don't levy those surcharges, and books short-haul flights where the fees are trivial to begin with. Get that one distinction right and the same 1,300 Avios goes from "meh" to genuinely excellent.
Where Avios Actually Wins
Avios is a distance-based currency, which means it's priced by how far you fly, not by what a cash ticket costs that day. That structure creates a handful of redemptions where it's hard to beat. Here are the ones worth transferring for.
| Redemption | Avios (one-way) | Why it's a sweet spot |
|---|---|---|
| Off-peak short-haul within Europe | from 4,000 | Band 1 city hops at off-peak pricing, with genuinely low taxes on most routes. The standout short-haul value — ideal once you're already over there. |
| BA short-haul "Reward Flight Saver" | from ~10,000 | Fees are capped low on these BA-operated hops — the opposite of BA long-haul, where the surcharges live. |
| Iberia off-peak transatlantic | varies (off-peak) | Iberia's own metal to Madrid at off-peak rates, with surcharges a fraction of BA's — the best way across the Atlantic on Avios in 2026. |
| American / Alaska partner metal | distance-based | Neither adds fuel surcharges of its own (≈$5.60 in fees on American). Strongest on routes to Latin America and Asia, where taxes stay low. |
| Short-haul American domestic (the old "sweet spot") | ~12,000–13,500 | Once 7,500 Avios, now much higher after two devaluations. Still surcharge-free, but no longer the bargain older guides quote — check the cash price before you book. |
Swipe the table sideways to see all three columns.
The through-line is the same in every row: you're either flying partner metal that doesn't add surcharges (American, Alaska, Iberia), or you're flying short and off-peak, where the fees are small no matter what. That's the opposite of the reflexive long-haul-BA-business booking, and it's why the same Avios balance produces wildly different value depending on what you point it at.
One more piece of the competitor delta, because it matters: the single most-quoted Avios "sweet spot" in older guides — 7,500 Avios for a short-haul American domestic flight — is no longer 7,500. Two devaluations in eighteen months pushed it to roughly 12,000–13,500 Avios one-way in economy. It's still surcharge-free, but if you land on a post that's still selling you the 7,500 number, that post hasn't been updated since 2024. Always check the cash price of the exact flight before you transfer.
Off-peak timing matters more than people expect, too. For U.S. travel, the off-peak windows tend to fall in late winter and late fall — roughly January through March and October into November — and hitting them can be the difference between a good redemption and a great one. For a broader look at which programs each Amex transfer partner unlocks, our Amex Membership Rewards transfer partners guide maps the sweet spots across the whole ecosystem, not just Avios.
Why "Avios" Isn't Just British Airways
This is the structural fact that unlocks the whole offer. Avios is a single shared currency across British Airways Club, Iberia Plus, Aer Lingus AerClub and a few others (Vueling, Finnair and more). Using the "Combine my Avios" tool, you can move Avios between these programs — and, helpfully, you can now shuffle between Iberia, Aer Lingus, Vueling and Finnair in a single step without routing through a British Airways account first.
What that means in practice: the program you transfer your Amex points into is not a lock-in. Send Membership Rewards to whichever Avios program you're set up with, then move the Avios to the one that actually shows the award you want — because award availability and pricing on the same flight can differ between the BA, Iberia and Aer Lingus booking engines. It's the same Avios; you're just shopping three storefronts.
One important caveat, because it trips people up. If you use a British Airways household account to pool Avios with a partner, you can only move your individual share to another Avios program — not the combined household total. Pool for booking on BA; don't assume the whole pot is portable.
Should You Transfer at All?
A 30% bonus is a discount, not a reason. The question isn't "is 1:1.3 a good rate" — it is — it's "do I have a specific award that Avios books well." If the answer is yes, this is a great week to move points. If the answer is "not yet, but I'll figure it out later," keep your Membership Rewards where they are.
The reason is that flexible points are an option, and transferring spends the option. Membership Rewards can become Avios, or Flying Blue, or Virgin Atlantic points, or a dozen other things — but Avios can only become Avios. Airline currencies also devalue, usually without much warning, and once your points are sitting in an airline program you've absorbed that risk. Speculative transfers — moving a big balance "because the bonus is good" — are the single most common way people end up worse off after a bonus, not better.
If you want the fuller version of this reasoning, along with how to earn Membership Rewards efficiently in the first place, our complete Amex Membership Rewards guide covers the earning side, and if you're weighing this bonus against the others live right now, the August 2026 transfer-bonus roundup lines them all up.
If you're chasing higher earning ceilings and premium travel perks alongside the transferable points, the Amex Platinum sits at the top of the Membership Rewards stack, and the lower-fee Amex Green earns Membership Rewards on broad travel and transit if you want an entry point. And if you'd rather pad a balance without opening anything, running your normal online shopping through Rakuten and taking the payout in Membership Rewards is the quiet way to top up before a bonus like this closes.
The Bottom Line
The 30% Amex-to-Avios bonus is a good offer with a narrow set of great uses. The rate is strong, it runs through September 27, and it applies across the whole Avios family — British Airways, Iberia and Aer Lingus — so you're never locked into the program you transferred into.
The mistake to avoid is treating this as a green light to funnel points into British Airways for a long-haul business seat, where carrier-imposed surcharges of several hundred dollars each way quietly claw back a big chunk of what the bonus gave you. The wins are quieter and more reliable: an off-peak European hop from 4,000 Avios, Iberia's own metal across the Atlantic, or surcharge-free partner flights on American and Alaska — just don't assume the old 7,500-Avios domestic pricing still holds, because it doesn't.
So the order of operations is short. Find the specific award first. Confirm which Avios program shows it and at what fee. Then — and only then — move exactly the Membership Rewards you need, take the 30%, and book. Do it in that order and this is one of the better points moves you'll make this year. Do it backwards and it's just a faster way to hold a devaluing currency.
