In September 2025, we saw the Capital One mileage program add Japan Airlines Mileage Bank as its newest transfer partner. We’ve just seen the program introduce its second transfer bonus to the program since launch, and it could represent a good deal. However, it still won’t quite get you a 1:1 transfer ratio.
However, with a 25% bonus, the transfer ratio is temporarily 1,000:975, so that’s pretty close to 1:1. Keep in mind that many popular Capital One cards earn 2x miles per dollar spent, so with this bonus, you could be earning close to two Japan Airlines miles per dollar spent.
I don’t think this 30% bonus is compelling enough to make a speculative transfer, but with a specific use in mind, this could be worthwhile.
A great solo travel tip spotted this week on One Mile at a Time.
