Hope this is the right thread - wanted to ask if anyone knew of when JAL Business award space is released to Alaska Airlines?

For context, I'm looking at a ORD - HND - SIN route, which is ~65K Alaska miles for the JAL business ticket. I see availability up until October 1, 2023, but am looking to book for say October 8/9/10, 2023, all of which I only see the economy class option. In fact, October 2, 2023 onward, I only see the economy class redemption option for this route. Is this because award availability is already all booked up or that it hasn't been released yet post October 1, 2023?
