Thanks very much for the warm welcome! I've really appreciated all the posters in this thread who are trying to figure out what's happening.

I usually follow BR routes, mostly YYZ/YVR to TPE. As others have mentioned, the historically typical two J seats per day have dropped to 1 J seat per day, and now no availability on AP for these routes in any fare class - at least for dates close to a year out, which is where I'm usually checking.

BR availability for intra-Asia routes like TPE-DPS or TPE-BKK is still visible on AP. But anything BR for the trans-pacific leg seems to be gone from AP. I haven't tried calling yet.
