I know that AS caches JAL availability, so I'm not sure if this is a result of that or something different.
I'm looking for TYO - PVG on 2/19/2020, which is within the 330 window. I'm noticing goose eggs on the AS website for biz/economy, but plenty of availability for both on BAs website. Curious when I should (if ever) expect these to hit AS? I'm trying to burn through my MP stash instead of transferring over MRs to BA to book.
