Which transfer bonuses are live through Oct. 31
Transfer bonuses reward you with extra miles when you move bank points to an airline partner for a limited time. The offers reported as live on October 20, 2026 are a 20% bonus from Capital One to British Airways through Oct. 21, a 30% bonus from Citi to JAL Mileage Bank through Oct. 24, and a 25% bonus from Amex to Air France/KLM Flying Blue through Oct. 31. A 50% bonus from Rove to JAL Mileage Bank also runs through Oct. 31. These are reported terms; confirm each one in your own bank or Rove account, because campaigns can differ by account.
Capital One to British Airways ends first
The Capital One to British Airways bonus is the most urgent on the list because the reported end date is Oct. 21. A 20% bonus is modest next to the others, but British Airways Avios are widely useful for short flights and partner awards. If you already have a specific booking in mind and enough Capital One miles, this is the offer to resolve first. If you do not, it is reasonable to let it lapse rather than move miles without a plan.
Citi to JAL Mileage Bank and the 30% bonus
Citi cardholders have a 30% bonus to JAL Mileage Bank through Oct. 24. JAL miles can be used on Japan Airlines and on several partner airlines, so the bonus matters mostly if you can see a real award you want to book. Check the award availability on JAL's own search before moving points, and confirm that the partner you want to fly is bookable with JAL miles.
Amex to Flying Blue and the 25% bonus
The Amex to Flying Blue offer adds 25% through Oct. 31. That gives the most time of the bank-based offers, which makes it the easiest to plan around. Flying Blue pricing varies by route and date, so compare the bonus-adjusted cost against what the same trip would cost in cash and in other programs before committing.
Rove to JAL Mileage Bank has the biggest bonus
Rove to JAL Mileage Bank is the largest reported bonus at 50% through Oct. 31. The catch is that Rove miles are earned only through the Rove portal, not with a credit card, so this helps only people who already hold a Rove balance or plan to use that portal. If you have no Rove miles, the bonus does not apply to you.
How to decide whether to transfer
A bonus is only valuable when it lowers the cost of a trip you would actually take. Start with the destination and dates, find an award seat that is bookable today, and price the trip in each program that could book it. Then apply the bonus and compare the final mileage cost with the cash fare. If the transfer saves little or the seat is not available, skip it. Points held in a flexible bank currency keep their options open, so moving them early to chase a percentage can cost more than it gains.
Who should pass on these offers
Skip a transfer if you have no specific award in mind, if you would be left with miles you cannot use, or if you are short on time to verify the terms. Transfers to airline programs are generally treated as final, so a mistaken transfer is hard to undo. Anyone relying on a balance that is also needed for a different trip should plan the whole itinerary first. These offers are reported terms and not personal guarantees, and bonus rates or dates can differ for individual accounts.
Checklist before you move points
Before you confirm any transfer, work through a short checklist: confirm the bonus and end date in your bank or Rove account, find a bookable award, compare the final cost with cash, check taxes and fees, and make sure the airline account is open and matches the traveler name. Save the screen showing the bonus in case you need to follow up later. If anything is unclear, wait and ask the bank or airline, because another bonus is likely to appear later.
