Thanks that is really helpful.
I am assuming 62 days before is when the Avios/redemption seats are released?
An unrelated question, but one I am hoping someone can help with.
If I book two segments close together on the Japan Explorer Pass for example OKJ-OKA-MMY or KIX-OKA-MMY, will JAL/Japan Transocean protect the connection between the two flights if there is a delay?
