Just over a week ago I flew HND-ITM in paid First. It was one of the cheaper fares, and although absolutely nothing I received from JAL gave any indication of a fare class, I believe it booked into A class (I can see the same fare available on the route, and it's only available on flights with A inventory).
The flight hasn't credited at all yet. And, confusingly, although the Qantas points calculator lists JAL First on that route as crediting 50SC, the
fare mapping table doesn't make any mention of 'A' class in any category (including those earning as 'economy plus premium/first surcharge').
Given 'A' isn't listed, should I just assume it's not eligible? And if it was eligible, how do you know how many SC the various 'x plus y surcharge' fares would earn, as it doesn't seem to be mentioned anywhere on the QFF site?

Edited to add: it's what the JAL site refers to as a 'Saver' fare:

Though I note those rules are the same link for an Economy class Saver, a Class J Saver, or a First Class Saver, so I'm not sure how helpful that is. No 'Tokubin' or other fare branding visible that I can see.
