Capital One Miles is offering a 30% transfer bonus when you transfer your miles to Japan Airlines Mileage Bank, through 2/28/26. With this bonus, the transfer ratio becomes nearly 1:1 (actually 1:0.975). That can make for some excellent deals with Japan Airlines Mileage Bank sweet spots.

Quick Thoughts
Japan Airlines Mileage Bank has only relatively recently come back on the radar for many points and miles folks, thanks to being added as both a Bilt transfer partner and a Capital One transfer partner in 2025.
While this program certainly has its quirks, those who can get through those quirks can be rewarded with things like being able to book Air France without surcharges, Emirates business class for a very reasonable rate, or flights on Japan Airlines with far better award availability (all linked within our post about best uses and also discussed on podcast episode 325).
Unfortunately, Japan Airlines is not ordinarily a 1:1 transfer partner from Capital One. However, with this transfer bonus, it is possible to get close to 1:1, with 1,000 Capital One miles becoming 975 Japan Airlines Mileage Bank miles. That can put many of the sweet spot uses within easier reach (and keep in mind that Bilt points transfer 1:1 to Japan Airlines, so you can combine points from both programs).
As noted, there are some key challenges to booking via Japan Airlines Mileage Bank. For starters, JAL only officially allows you to redeem miles for yourself and closely related family members. Additionally, newly-created Japan Airlines accounts can not redeem miles for a minimum of 7 days. If you have not yet joined Japan Airlines Mileage Bank, you should do so now and wait to transfer until at least 7 days have passed to make sure that you still see the availability that you wish to book. You can read more about these restrictions in the linked post for best uses above.
This could certainly be a useful bonus if you find availability and you have an account that is already seasoned and ready to redeem.

Ugggh! I transferred over 300,000 C1 miles to JAL just a couple of weeks ago. Whenever I make a significant transfer of credit card points, I should probably just post on the frequent miler facebook group that I have done so, because it almost always means a transfer bonus is imminent. Although, the truth is, that I got some unicorn 55,000 mile redemptions for 2 in J, so I ended up doing ok. Still, JAL is such a great program that I’m actually thinking about transferring some proactively to take advantage of this bonus. If I do, I’ll post that to FB too, because it will almost certainly mean that JAL is about to gut the program!
