You have a stack of bank points and a Japan trip in mind. Then a JAL transfer bonus appears, promising 50% more miles. Should you move your points now, or is a smaller bonus from a different bank actually the better deal? And does a bigger headline percentage always win?
Those questions matter because the headline number hides the real maths. As of October 2026, two JAL transfer bonuses are live at once: Rove Miles at 50% and Citi ThankYou at 30%. A third, Capital One's 30% offer, ended on September 30, 2026. Because each bank starts from a different base ratio, the program with the smaller bonus can still leave you with fewer JAL miles.
In this guide, you'll see every bank that reaches JAL Mileage Bank, the two live bonuses compared on effective ratio, and a simple rule for when a JAL transfer bonus is worth taking.
Key Takeaways
- Two JAL bonuses are live as of October 2026: Rove Miles +50% (through October 31) and Citi ThankYou +30% (through October 24). Capital One's +30% ended September 30.
- Effective ratio beats the headline percentage. Rove's +50% on a 1:1 base gives 1.5 JAL miles per point, more than Citi's no-fee +30% (0.91) or Capital One's expired +30% (0.975).
- Four banks reach JAL directly: Rove and Bilt at 1:1, Citi at 1:1 or 1:0.7 depending on your card, and Capital One at 1,000:750.
- A bonus only adds value when the resulting JAL miles (worth about 1.5¢ each) beat your bank's own baseline value.
- JAL business class to Japan starts near 55,000 miles one-way, which Rove's bonus funds for about 36,700 Rove miles.
Which Banks Transfer to JAL Mileage Bank
Before a bonus matters, you need a path into the program. Fewer banks reach JAL than reach most airlines, and the base ratios are not all 1:1, which changes the maths before any bonus applies.
| Bank program | Base ratio to JAL | Notes |
|---|---|---|
| Rove Miles | 1:1 | 2,000-mile minimum, then 100-mile steps |
| Bilt Rewards | 1:1 | Transfers are typically instant |
| Citi ThankYou Points | 1:1 on annual-fee cards; 1:0.7 on no-fee cards | Your card type sets your ratio |
| Capital One Miles | 1,000:750 (effectively 1:0.75) | The lowest base of the four |
Two points on this table decide real outcomes:
- Amex, Chase, and Wells Fargo do not transfer to JAL directly. Amex Membership Rewards can reach JAL only indirectly, by routing through Cathay Pacific Asia Miles first, which adds a step and a second ratio.
- Marriott Bonvoy also reaches JAL at 3:1, plus a 5,000-mile bonus per 60,000 points transferred, but that is a hotel currency rather than a bank.

The Two Live JAL Bonuses Right Now
Two banks are running JAL bonuses in October 2026, and they are not equal. The table below shows each bonus on its effective ratio, which is the base ratio multiplied by the bonus. That is the number that decides how many JAL miles actually land in your account.
| Bank | Bonus | Base ratio | Effective ratio | Ends |
|---|---|---|---|---|
| Rove Miles | +50% | 1:1 | 1:1.5 | October 31, 2026 |
| Citi ThankYou (annual-fee card) | +30% | 1:1 | 1:1.3 | October 24, 2026 |
| Citi ThankYou (no-fee card) | +30% | 1:0.7 | 1:0.91 | October 24, 2026 |
The maths behind each row is simple: base ratio × (1 + bonus). Rove's 1:1 base × 1.5 = 1:1.5. Citi's annual-fee 1:1 base × 1.3 = 1:1.3. On a no-fee Citi card, 0.7 × 1.3 = 0.91, so you end with fewer JAL miles than points you started with.
Both live offers are confirmed by Frequent Miler for Rove and Upgraded Points for Citi.
Capital One ran a +30% bonus on its 1,000:750 base through September 30, 2026. That worked out to an effective 1,000:975, or 0.975 JAL miles per Capital One mile. It has now ended, so Capital One sits at its base 1,000:750 until the next promotion.
Why the Headline Percentage Lies
This is the section most bonus posts skip. A 50% bonus and a 30% bonus are not two points apart in value, because they start from different base ratios and feed into a currency worth about 1.5¢ per mile. The table converts each route into cents of value created per bank point, using the JAL figure from our points valuations.
| Transfer route | Effective ratio | JAL value created* | Bank's own baseline | Worth it? |
|---|---|---|---|---|
| Rove +50% | 1:1.5 | ~2.25¢/mile | 1.6¢ | Yes |
| Citi +30% (annual-fee) | 1:1.3 | ~1.95¢/point | 1.8¢ | Marginal yes |
| Citi +30% (no-fee) | 1:0.91 | ~1.37¢/point | 1.8¢ | No |
| Capital One +30% (expired) | 1:0.975 | ~1.46¢/mile | 1.85¢ | No |
| Bilt (no bonus) | 1:1 | ~1.5¢/point | 2.0¢ | Only for a specific award |
*JAL miles valued at 1.5¢ each, a TransferPoints estimate, not a guarantee.
The pattern is clear once you see it. Rove's +50% turns each mile into 1.5 JAL miles, or 1.5 × 1.5¢ = 2.25¢ of value, well above Rove's own 1.6¢ baseline. Citi's +30% on an annual-fee card clears its baseline by a hair. Every other route, including Capital One's +30% while it ran, produced less value than the bank's points are typically worth elsewhere. A bigger headline percentage on a weaker base ratio still loses.
What a Bonus Saves on a Real JAL Award
Round numbers only matter against a real award. JAL business class between the U.S. and Japan starts near 55,000 miles one-way on JAL-operated flights, as of October 2026, with prices varying by season. Here is what that single award costs through each live route.
| Route in | Effective ratio | Bank points needed |
|---|---|---|
| Rove +50% | 1:1.5 | 36,700 (55,000 ÷ 1.5 = 36,667, rounded up to a 100-mile step) |
| Citi +30% (annual-fee) | 1:1.3 | ~42,400 (55,000 ÷ 1.3) |
| Citi +30% (no-fee) | 1:0.91 | ~60,500 (55,000 ÷ 0.91) |
| Bilt (no bonus) | 1:1 | 55,000 |
The spread is striking: the same seat costs 36,700 points through Rove but more than 60,000 through a no-fee Citi card. Round every transfer up to your bank's increment, since you cannot transfer a fraction and leftover JAL miles cannot move back.
Transfer Calculator
Transfer Now or Wait?
A JAL bonus is only useful if it funds an award you will actually book. Use this quick framework before you move anything.
- Transfer now if: you have found an available JAL award seat, the effective ratio beats your bank's baseline value, and the bonus deadline is close.
- Wait if: you have no confirmed seat, or your only route is a sub-baseline ratio such as a no-fee Citi card or Capital One's base 1,000:750.
- Skip JAL entirely if: another oneworld program prices the same flight more cheaply, or your bank's points are worth more on a different partner.
Common mistakes to avoid:
- Transferring before you confirm a seat. Transfers are one-way, so search award space first and move points only once you can book.
- Chasing the biggest percentage. A 30% bonus on a 1:0.7 base is worse than a 50% bonus on a 1:1 base, as the tables above show.
- Forgetting the Citi no-fee penalty. On a no-fee ThankYou card, even a +30% bonus leaves you below 1:1.
- Assuming Amex or Chase reach JAL. Neither transfers directly, so plan around the four banks that do.
Track JAL Bonuses with TransferPoints
JAL bonuses are short, unannounced, and spread across banks that each use a different base ratio. One offer can beat another even when its headline percentage is smaller, and transfers are irreversible once made. That combination makes JAL an easy program to misjudge.
TransferPoints puts every live bonus, base ratio, and transfer time in one place so you can compare effective ratios at a glance instead of reading five bonus posts.
- Bonus Tracker: see which JAL bonuses are live and when each one ends.
- Transfer Calculator (/#calculator): convert a bonus into real JAL miles for your balance.
- Program pages (Rove, Citi): check each bank's base ratio before you transfer.
- FlightPoints: search JAL award availability before you move a single point.
Our Flying Blue transfer bonus guide and LifeMiles transfer bonus guide apply the same effective-ratio logic to other programs.
Conclusion
The best JAL transfer bonus is rarely the one with the biggest number on it. Rove's +50% wins in October 2026 because it sits on a 1:1 base and lands around 2.25¢ of value per mile, while Citi's +30% only clears its baseline on an annual-fee card and loses on a no-fee one. Capital One's +30%, now expired, never beat the bank's own typical value even while it ran. The lesson holds beyond this month: judge every offer on its effective ratio, not its headline.
Because bonuses shift between banks and ratios differ by card, checking them one by one wastes time and invites mistakes. A single view of the live offers, base ratios, and effective maths makes the timing call clearer and the transfer more confident.
Check the live bonus tracker before your next transfer to see whether a JAL transfer bonus actually changes your maths.
Frequently Asked Questions
Which banks transfer to JAL Mileage Bank?
Four US bank currencies transfer to JAL directly: Rove Miles and Bilt Rewards at 1:1, Citi ThankYou Points at 1:1 on annual-fee cards or 1:0.7 on no-fee cards, and Capital One Miles at 1,000:750. Amex, Chase, and Wells Fargo do not transfer directly. Marriott Bonvoy also reaches JAL at 3:1, but it is a hotel currency rather than a bank.
Is the Capital One JAL transfer bonus still available?
No. Capital One's 30% transfer bonus to JAL ended on September 30, 2026. It applied to the base 1,000:750 ratio, giving an effective 1,000:975, so it never quite reached parity even at its best. Capital One now transfers at its base 1,000:750 rate until it runs another promotion, which it has not announced as of October 2026.
Why does a 50% bonus beat a 30% bonus by more than the difference?
Because the bonus multiplies the base ratio, not a flat value. Rove's +50% sits on a 1:1 base, giving 1.5 JAL miles per point. Citi's +30% on a no-fee card sits on a 1:0.7 base, giving only 0.91. The starting ratio decides as much as the bonus, so always compare effective ratios rather than headline percentages.
How long do JAL transfers take?
It varies by bank, and JAL transfers are not always instant. Bilt transfers to JAL are typically immediate, while other banks can take anywhere from a few hours to a couple of days. Never transfer against a tight bonus deadline without a buffer, and always confirm your award seat before you move points.
Is transferring to JAL worth it without a bonus?
Usually only for a specific JAL redemption you cannot book more cheaply elsewhere, such as JAL first or business class across the Pacific. At a base value near 1.5¢ per mile, JAL sits below the baseline value of most banks that reach it, so a no-bonus transfer makes sense only when you have the exact award in mind.
