Indeed, the initial bonus offered by ANA is fantastic. In comparison, JAL's initial bonus is quite lacking. However, since I want to accumulate JAL points, I've been doing some research. I heard that D points can be exchanged for JAL points, although they get reduced by half. You need to accumulate at least 1,000 points to make the transfer. I had never heard that Rakuten points could be transferred. Also, I heard that Moppy points can be exchanged for JAL miles, but I haven't actually done the transfer myself yet. I wonder if there are any other points that can be exchanged for JAL points?
