Amex Membership Rewards is running a 30% transfer bonus to British Airways Executive Club, Iberia Plus, and Aer Lingus AerClub through September 27, 2026. That turns 100,000 points into 130,000 Avios—enough to unlock serious business class redemptions on Iberia, Qatar Airways, and Japan Airlines before the window slams shut.
These programs share Avios freely, so transfer to one and move them around. The bonus is live now, transfers are usually instant, and availability on partner metal hasn't dried up yet. But don't sit on this; September 27 isn't far away, and Amex doesn't hand out 30% bumps every month.
Iberia Business Class to Spain: The Obvious Winner
Iberia's distance-based chart is still one of the best deals in the game. Off-peak business class from the Northeast US (JFK, BOS, IAD) to Madrid runs 34,000 Avios one-way for flights in the 3,001–4,000 mile band. With the bonus, that's roughly 26,200 Amex points each direction.
Round-trip? About 52,400 Amex points plus modest taxes around $100–200 per direction. Cash fares on these routes are hovering in the $3,000–5,000 range round-trip right now. The math is stupidly good, especially on Iberia's A330 or A321XLR flights that actually feel premium.
Book directly through Iberia Plus after transferring. Availability opens reasonably far out and isn't phantom like some partners. If you're staring at a trip to Spain or connecting onward in Europe, this is the one to hammer first.
Qatar Qsuites via BA Avios: Still Absurdly Cheap
Transfer to British Airways and book Qatar Airways Qsuites with BA Avios. US to Doha in business is often 50,000–70,000 Avios one-way depending on distance and demand. The bonus drops that to roughly 38,500–54,000 Amex points.
Qsuites remain the best business class product flying, with sliding doors, lie-flat seats, and actual privacy. Cash prices for these routes routinely exceed $6,000–9,000 one-way in peak seasons. Even on connecting itineraries to the Middle East, India, or Africa, the value holds up better than most US carriers' domestic first.
Yes, BA's surcharges can sting on their own metal, but when you're redeeming on Qatar it's mostly carrier-imposed taxes that stay reasonable. Search on ba.com, then call if the partner space doesn't show—agents can still ticket many of these.
JAL Business Class to Asia: The Dark Horse
Japan Airlines business via BA Avios is the sleeper hit. US West Coast to Tokyo often prices around 50,000–60,000 Avios one-way in business; East Coast pushes 65,000–80,000. The 30% bonus shaves that down nicely—think 50,000 Amex points or less from the West Coast.
JAL's Sky Suite seats are excellent, the service is impeccable, and the food beats whatever sad sack meal your Amex Platinum lounge is serving. Cash fares are running $5,500–7,000 round-trip right now. You do the valuation.
Availability is tighter than Iberia but better than it was a few years ago. Check both ba.com and the Qatar site (after transferring Avios there) because pricing can differ. Avoid peak cherry blossom and summer dates unless you enjoy pain.
One note: BA's dynamic pricing means some routes fluctuate wildly. The bonus still improves the effective cost enough that most sweet spots remain compelling compared to cash or other programs.
What to Do Before September 27
Calculate exactly how many Amex points you need for your target trip, transfer only that amount (plus a small buffer), and book immediately. These programs can devalue or change charts without warning, and the bonus won't be here forever.
Prioritize Iberia to Madrid if Europe is on the menu. Go for Qsuites to Doha or beyond if you want to feel like a baller for pennies on the dollar. JAL makes sense for Asia if the dates align.
Log in, check availability on ba.com and iberia.com today, and pull the trigger. The difference between 100K and 130K Avios is the difference between a decent redemption and one you'll actually brag about in the group chat. Don't waste the multiplier on economy or short-haul.[[1]](https://onemileatatime.com/deals/amex-british-airways-avios-transfer-bonus/)[[1]](https://onemileatatime.com/deals/amex-british-airways-avios-transfer-bonus/)[[2]](https://thriftytraveler.com/deals/points/amex-british-airways-transfer-bonus/)[[3]](https://awardtravelfinder.com/award-charts/iberia)
