JAL Mileage Bank - Limited D inventory on JFK-NRT

I'm planning Amex two-for-one travel on JL, preferably originating at JFK. I know it's not the lowest possible discount, but it's appropriate for my purposes.

The ticket books into D inventory. Previously, that has never been a problem for me on JFK-NRT with 4+ weeks of advance notice. But looking at outbound travel the week of November 2, I see D0 all week.

Any thoughts? Others faced similar problems? I feel I'm booking far in advance, in a reasonably high bucket (not, say, "I"). I was hoping for more options.

I'd rather not originate at ORD -- further afield from where my companion and I are starting, requiring longer and more costly domestic connections, and reducing the transpacific flight time. Of course we can do this if needed, but at $$$$ for the two-for-one, we were hoping to get our preferred point of origination.

I'm AA EXP, OneWorld emerald. Any way to use that to get the required inventory? Booking through Amex, that may be hard: I wonder whether Amex would even make a two-for-one reservation without D inventory on specified segments.

I suspect JAL is holding off those seats until Oct 1 when they reintroduce the fuel surcharge. I am trying to book a LAX-HKG roundtrip in Dec and all I see are Y class which costs $3K!!! But this is just my wild guess...

I take it back, I just got my November trip (also week of Nov 2) confirmed this morning (still on waiting list for Dec). So JAL probably is not holding seats, at least not for the week of Nov 2. You just have to waitlist ;)
