They kicked off that partnership with a 30% transfer bonus, then followed it up with another 30% bonus for the month of February.
Now, just a month since that previous 30% transfer bonus to Japan Airlines ended, Capital One has launched another one.

Quick Thoughts
Capital One miles normally transfer to Japan Airlines on a 1,000:750 basis. This transfer bonus therefore increases that ratio to almost parity at 1,000:975. While it’s a shame that the normal ratio isn’t 1,000:1,000 as the bonus would make that 1,000:1,300, it is still possible to get good value from an almost 1:1 transfer ratio.
