Amex to Avios 30% Transfer Bonus: How to Use It Before September 27, 2026

Last updated: August 13, 2026

Quick Answer

American Express U.S. is offering a 30% transfer bonus from Membership Rewards to British Airways Executive Club, Iberia Plus, and Aer Lingus AerClub through September 27, 2026 (11:59 p.m. Mountain Time). That makes the effective ratio 1,000 Amex points = 1,300 Avios. The bonus is only worth taking if you already have a specific redemption in mind, because Avios awards on British Airways metal carry heavy carrier-imposed surcharges that can erase the value. The best uses in this Amex to Avios transfer bonus 2026 window are Iberia transatlantic business class, Aer Lingus flights from the U.S. East Coast, and short-haul partner flights on American, Alaska, Qatar, and Japan Airlines.

Key Takeaways

• The bonus runs August 3 through September 27, 2026 and applies to all three Avios programs: British Airways, Iberia, and Aer Lingus.
• Effective rate is 1,300 Avios per 1,000 Amex points, hard-coded into the Amex transfer screen, no registration or promo code needed.
• Transfers to Avios programs are usually instant, but Amex allows up to 72 hours, so don’t transfer at 11:50 p.m. on deadline night.
• Avios balances can be combined across BA, Iberia, and Aer Lingus, so you can transfer to whichever program shows the bonus and move Avios where you need them.
• Iberia is the surcharge-friendly option for transatlantic business class; British Airways flights from London can add several hundred dollars per person in fees.
• Avios transfers are one-way and irreversible. There is no way to move Avios back to Membership Rewards.
• Skip the bonus if you have no target award, if your dates are inflexible, or if a competing partner (Virgin Atlantic, Air France-KLM, Qatar) is a better fit for your route.

What Is the Amex to Avios 30% Transfer Bonus and When Does It Expire?

The Amex to Avios 30% transfer bonus is a limited-time promotion for U.S. Membership Rewards cardmembers that increases the standard 1:1 transfer ratio to 1:1.3 for three Avios-based loyalty programs. It began August 3, 2026 and ends September 27, 2026 at 11:59 p.m. Mountain Time.

Participating programs:

• British Airways Executive Club (now branded The British Airways Club)
• Iberia Plus
• Aer Lingus AerClub

There’s no separate registration. Amex builds the bonus directly into the transfer ratio, so when you open the transfer page you’ll see 1,000 Membership Rewards points listed as 1,300 Avios. If you don’t see that ratio, you’re either looking at a non-participating partner or the promotion has ended.

What happens after September 27, 2026? The ratio reverts to the standard 1:1. Amex has historically run Avios bonuses at 30% to 40% roughly once or twice a year, so another one is likely, but not guaranteed, and not on any published schedule. Do not transfer speculatively on the assumption that you can “catch the next one” later at a better rate.

Rule of thumb: a transfer bonus is a discount on a purchase you were already going to make. It is not a reason to make the purchase.

How Does the Amex Avios Transfer Bonus Work, and How Much Do You Get?

The math is simple: multiply your transfer amount by 1.3. There is no cap published on the promotion, and no separate opt-in step.

Amex points transferred	Avios received (30% bonus)	Avios at standard 1:1
10,000	13,000	10,000
25,000	32,500	25,000
50,000	65,000	50,000
100,000	130,000	100,000
150,000	195,000	150,000

Minimum and increments. Amex requires a minimum of 1,000 Membership Rewards points per transfer to airline partners, in 1,000-point increments. So the smallest bonused transfer available is 1,000 points to 1,300 Avios. Verify both the minimum and the ratio on the Amex transfer screen before confirming, since Amex occasionally adjusts partner-level rules.

Which Amex cards qualify? Any U.S. consumer or business card that earns Membership Rewards points and has transfer privileges. That includes the Platinum Card, Gold Card, Green Card, Amex EveryDay and EveryDay Preferred, Business Platinum, Business Gold, and Blue Business Plus. Cards that earn cash back (Blue Cash Preferred, Blue Cash Everyday) or Delta SkyMiles do not participate, because those cards don’t earn Membership Rewards. If your Membership Rewards points sit on multiple cards in the same account, they pool and transfer from a single balance.

One important cost note: Amex charges a $0.0006 per point excise tax offset fee on transfers to U.S.-based airline programs, capped at $99. British Airways, Iberia, and Aer Lingus are foreign programs, so no fee applies to these transfers. That’s a small but real advantage over transfers to Delta or JetBlue.

Can you use the bonus more than once? Yes. There’s no stated limit on the number of bonused transfers during the window. You can transfer 20,000 points today and another 40,000 in three weeks and receive the 30% bonus on both. That flexibility matters; it means you can transfer exactly what a confirmed award requires rather than dumping a large balance in one move.

How the Avios Ecosystem Works Across British Airways, Iberia, and Aer Lingus

Avios is a shared currency. British Airways, Iberia, Aer Lingus, and Qatar Airways all issue Avios, and you can move Avios between your own accounts in these programs at a 1:1 ratio at no cost using the “Combine my Avios” feature. That means the program you transfer into during this Amex to Avios transfer bonus 2026 window is not necessarily the program you’ll book from.

Practical implications:

• You do not need to pick perfectly. Transfer to any of the three, then combine Avios into whichever account offers the best pricing and lowest fees for your route.
• Account age rules apply. Iberia Plus has historically required an account to be open for a period (commonly cited as about 90 days) with some activity before it can combine Avios. If Iberia is central to your plan, open the account now and confirm eligibility inside your Iberia Plus profile before transferring.
• Pricing differs between programs even for the same flight. Iberia Plus uses a distance-based chart with different band cutoffs than British Airways. Aer Lingus AerClub prices its own transatlantic flights on a separate chart. Always price the same itinerary in at least two Avios accounts.
• Qatar Privilege Club also uses Avios and is not an Amex transfer partner in the U.S., but you can combine Avios into it, useful for booking oneworld partners with Qatar’s own award pricing.

Can you transfer to Avios if you’re not already a member? Yes, but you must create the frequent flyer account first. Amex requires the loyalty account number and a name that matches your Amex profile. Sign up on the airline’s site (free, takes a few minutes), then add the program in the Amex transfer portal. Name mismatches are the single most common cause of a failed transfer.

The Best Avios Sweet Spots to Target in the Amex to Avios Transfer Bonus 2026 Window

The best use of Avios after transferring is short-haul oneworld partner flights and transatlantic business class on carriers that don’t pass through large surcharges. Avios pricing is distance-based on many partner awards, which creates genuine sweet spots that dynamic programs can’t match.

Sweet spots worth targeting now:

• Iberia Business Class, U.S. East Coast to Madrid. Off-peak pricing has historically been the standout Avios redemption, with modest carrier fees compared to British Airways. Availability is thin and often opens in bursts, so check a wide date range.
• Aer Lingus, U.S. to Dublin. Book through AerClub or British Airways. Aer Lingus does not impose the large surcharges British Airways does, and Dublin is a workable gateway to the rest of Europe.
• American Airlines and Alaska Airlines short-haul domestic. Short segments under about 650 miles price very cheaply in Avios, and taxes are usually under $6. This is the highest cents-per-point use for most people.
• Japan Airlines domestic and intra-Asia. JAL segments booked with Avios remain a strong value, especially positioning flights within Japan.
• Qatar Airways Qsuite via Avios. Priced on a distance chart, with fees that vary by origin. Worth pricing in both British Airways and Qatar Privilege Club.
• British Airways Reward Flight Saver on intra-Europe routes. Caps the cash portion, which limits the surcharge damage on short European hops.

For a fuller breakdown of where Avios beats other currencies route by route, see the walkthrough in the Chase to Avios 30% transfer bonus strategy guide, which covers the same sweet spots from the Ultimate Rewards side.

Quick example with clear assumptions. Assume a one-way Iberia business class award from Boston to Madrid priced at 34,000 Avios plus roughly $95 in taxes and fees (off-peak, sample pricing, verify live). At the bonused ratio, 34,000 Avios costs about 26,150 Membership Rewards points. If the cash fare is $2,100 one-way, that’s roughly 7.7 cents per point in value. Same award without the bonus costs 34,000 Amex points, or about 5.9 CPP. The bonus improves the redemption by around 30% on a per-point basis, which is exactly the point.

Edge case to watch: married segments. British Airways and Iberia sometimes only release partner award space when segments are booked together in a specific combination. If a connecting itinerary won’t price, try booking the segments as separate one-ways and compare the total.

Fuel Surcharges: The Trap That Ruins Most Avios Redemptions

Carrier-imposed surcharges are the reason many Avios transfers turn into a bad decision. British Airways adds substantial surcharges on its own long-haul flights, especially those departing London Heathrow, and those charges are paid in cash on top of the Avios.

How to keep the cash cost down:

• Avoid British Airways metal out of London on long-haul premium cabins. Business class from LHR to the U.S. can carry several hundred dollars per person in surcharges plus the UK Air Passenger Duty. Two people in Club World can face four figures in cash.
• Fly Iberia instead when the route allows. Iberia’s carrier-imposed charges on Madrid transatlantic flights are materially lower than British Airways’.
• Use Aer Lingus for Ireland and onward Europe. AerClub and BA-issued Aer Lingus awards avoid the worst of the surcharge structure.
• Depart from Europe rather than the UK where possible. Madrid, Dublin, and other continental gateways avoid UK departure taxes on the outbound.
• Price American Airlines and Alaska segments in Avios. U.S. domestic partner awards typically carry only the mandatory $5.60 security fee each way.
• Always compare the total. Add the Avios cost (converted to Amex points at 1:1.3) plus cash fees, then compare against the cash fare. If the cash fees alone are 25% or more of the paid fare, the redemption usually isn’t worth it.

Common mistake: treating the Avios number as the whole price. A 50,000-Avios business class seat with $850 in surcharges is often worse than a 70,000-mile award elsewhere with $50 in taxes. Run the full math before transferring, not after.

How to Transfer Step by Step Before the Deadline

Transfer only after you’ve confirmed award space, then move the exact number of points needed. Amex transfers to Avios programs are typically instant but can take up to 72 hours, so build in buffer time.

Step-by-step checklist:

1. Search award space first. Use the British Airways multi-city award tool, the Iberia site, and a third-party award search tool to confirm the seats exist on your dates.
2. Open the needed loyalty accounts. Create British Airways Club, Iberia Plus, and/or Aer Lingus AerClub accounts with your exact legal name as it appears on your Amex profile.
3. Price the same itinerary in each program. Note both the Avios required and the cash surcharge. Choose the lowest combined cost.
4. Calculate the Amex points needed. Divide the Avios required by 1.3, then round up to the next 1,000-point increment.
5. Link the program in the Amex transfer portal. Confirm the screen shows 1,000 to 1,300 before proceeding.
6. Transfer only that amount. Leftover Avios expire under program activity rules and cannot be returned to Amex.
7. Book immediately once Avios land. Award space can disappear within hours. If Avios haven’t posted within 72 hours, contact Amex.
8. Combine Avios if needed using “Combine my Avios” to move the balance to the booking program.

Transfer bonus not working? Troubleshoot in this order:

• Confirm the promotion is still live and you’re a U.S. Membership Rewards cardmember (the offer is U.S.-only).
• Check that your card actually earns Membership Rewards and has transfer eligibility. Some newly opened accounts have a brief hold.
• Verify the name on the airline account matches Amex exactly, including middle name conventions.
• Clear cookies or try a different browser; the transfer page occasionally caches an old ratio.
• If the transfer posted at 1:1, call Amex Membership Rewards. Bonuses applied incorrectly during a live promotion are usually corrected retroactively, but you’ll need to ask.
• If Avios haven’t arrived after 72 hours, request the transfer reference number from Amex and open a case with the airline.

Amex to Avios vs Other Transfer Bonuses: Is It Worth It Compared to Cash Back?

The Avios bonus is a good offer, but it isn’t automatically the best available. Compare it against competing bonuses and against the guaranteed value of cashing out before you commit.

How it stacks up:

• Versus Virgin Atlantic bonuses. Virgin Flying Club bonuses (Amex has run 30% to 40% offers) are better if your target is ANA or Delta One transatlantic, but Virgin availability is unpredictable. See the Virgin Atlantic 30% transfer bonus breakdown for that comparison.
• Versus LifeMiles bonuses. Avianca LifeMiles has no fuel surcharges at all, which often beats Avios on Star Alliance premium cabins even at a smaller bonus percentage. The Amex to LifeMiles 15% bonus guide walks through the math.
• Versus hotel bonuses. Large hotel bonuses look impressive but usually deliver lower cents per point. The Amex to Hilton transfer bonus analysis shows why a bigger percentage doesn’t mean better value.
• Versus other bank programs. If you also hold Ultimate Rewards or Capital One miles, check the Chase vs Amex vs Citi vs Capital One transfer partner comparison before deciding which currency to spend.

Versus cash back. Membership Rewards points cash out at roughly 0.6 cents each through statement credits, and around 1.0 cent through the Amex travel portal on some cards. A bonused Avios redemption at 5 to 8 CPP is clearly better math, provided you actually book the award. The comparison only holds if the flight happens. Points that sit in an Avios account for two years through a devaluation are worth less than cash back you took immediately.

For a broader view of where Avios sits among Amex’s partners, the Amex transfer partners ranked for 2026 covers relative value across the full lineup.

When You Should Skip This Bonus Entirely

Skip the transfer if you don’t have a specific award you can book within the next few weeks. A 30% bonus is not enough to justify locking points into a single airline currency with real devaluation risk.

Not worth it if:

• You have no confirmed award space and no flexible date range to work with.
• Your route requires British Airways metal from London in a premium cabin, where surcharges can exceed the cash value of the award.
• You’re speculating on future travel more than a year out. Avios pricing has changed repeatedly, and Iberia off-peak awards in particular have been adjusted.
• Your target airline is served better by another currency, for example, Star Alliance business class through LifeMiles or Air France-KLM Flying Blue.
• Your Membership Rewards balance is small enough that the bonus produces a partial award you can’t complete.

Best for: cardmembers who have already found Iberia or Aer Lingus transatlantic award space, need a top-up to reach an exact Avios total, or plan frequent short-haul American and Alaska awards where Avios pricing beats AAdvantage.

Not for: anyone hoping to bank Avios “for later.” Transfers are one-way. Amex will not reverse them.

FAQ

When exactly does the Amex Avios 30% bonus expire? The promotion ends September 27, 2026 at 11:59 p.m. Mountain Time. Transfers must be initiated by that deadline, and because posting can take up to 72 hours, initiate at least a day early to be safe.

How long does it take to transfer Amex points to Avios? Transfers to British Airways, Iberia, and Aer Lingus are usually instant or complete within a few minutes. Amex officially allows up to 72 hours, and occasional delays do happen during high-volume promotions.

Which Amex cards qualify for the Avios transfer bonus? Any U.S. card earning Membership Rewards points with transfer privileges, including Platinum, Gold, Green, Business Platinum, Business Gold, Blue Business Plus, and Amex EveryDay. Cash-back and Delta co-branded cards do not qualify.

What is the minimum number of Amex points needed for the bonus? Amex requires a minimum of 1,000 Membership Rewards points per airline transfer, in 1,000-point increments. That yields 1,300 Avios at the bonused rate. Confirm current minimums on the transfer screen.

Can I use the Avios transfer bonus more than once? Yes. There is no published limit on the number of bonused transfers during the promotion window, so you can make multiple transfers as you confirm separate awards.

Can I transfer Amex points to Avios if I’m not a member yet? Yes. Open a free British Airways Club, Iberia Plus, or Aer Lingus AerClub account first, then link it in the Amex transfer portal. Make sure the name matches your Amex profile exactly to avoid a failed transfer.

Can I move Avios between British Airways, Iberia, and Aer Lingus? Yes, at 1:1 with no fee using “Combine my Avios.” Iberia Plus may require the account to be open for a period with some activity before combining, so verify eligibility in your Iberia profile first.

Conclusion and Next Steps

The 30% Amex to Avios transfer bonus improves an already useful currency, but it rewards preparation rather than speed. The people who get real value from this window are the ones who search award space first and transfer second.

Do these three things before September 27, 2026:

1. Search award space now for Iberia and Aer Lingus transatlantic dates, plus any short-haul American or Alaska segments you need. Pull up a wide date range and note both Avios and cash fees.
2. Open and verify your Avios accounts, especially Iberia Plus, which may need account age before you can combine balances.
3. Transfer the exact amount needed, rounded up to the nearest 1,000 Amex points, and book the same day the Avios post.

If your route doesn’t line up with an Avios sweet spot, don’t force it. Check whether another Amex partner serves the itinerary with lower surcharges, or hold your Membership Rewards points until a bonus matches a redemption you actually want.
