They admit that there's no rule against it, just they can't do it. Yesterday there was D1 to KUL but of course they didn't check it until today and JL removed the D already and now only J and C are available.

Having said that, I think JL has done a pretty solid job of selling premium cabins this summer to SE Asia because quite a few routes are even low on J inventory for the week I'm checking. .

There have been a few people with GDS terminals in the pricing thread you might reach out to to check availability with the correct POO. Sounds likely the problem. But JL is terribly tight on D availability at least for the next couple of weeks, I reckon because a lot of Obon holiday period travel ex-Japan during August.
