You should still earn whatever the original ticket (as if not upgraded) would have earned.

Thank you so much for the clarification!

Edit: Mistake, did not see that there was another page and it was already answered.

From my experience yes. Availability is not showing on Aeroplan despite Lifemiles showing it. I also ran into a lot of "general technical failure" messages on the Aeroplan booking engine as well.

or it might be because EVA Air somehow block Aeroplan vice versa (Aeroplan blocked EVA Air) for BR35/BR36 YYZ-TPE flights

Cause I called twice to confirm Z class has more than 5 seat for 3 different days, in both cases, went back to Aeroplan website within 30 seconds to complete the upgrade, No seat is available.in Aeroplan's website. (Obviously I booked B class already)

I don't think consensus has been reached, but seems like previous discussion in this thread has gravitated toward neither Z nor I class being a perfect indicator of SAUA availability. I've read I, X, and Z all being mentioned by themselves or in combination.

I think the only thing that's certain is if BR doesn't see Z available, then one can be fairly certain that *A won't have the Z either. If BR has Z, then how many of those seats are also released to partners probably depend on how full both the Y and J cabins are.

I agree... but.. I highly doubt that either Y or J cabins are reached capacities for November's flight.. which is the one I tried to book without any luck.

Based on supplied data points from many FT'ers, consensus is actually quite clear that SAUA availability is linked with Z and not I. What's less clear (for obvious reasons) is that EVA may hold back some upgrade inventory for own-program members (to be fair, this is something that has been rumored/reported on this forum for years).

I was able to score an upgrade for my TPE-SFO this coming sunday using 38,000 Asiana Miles. Too bad no seat availability for my CEB-TPE segment. This is my first time flying business class on a long haul flight, I'm excited!!

You will enjoy it. Did you get a window seat?

I called and confirmed Z was available, then almost immediately after that, booked and tried to SAUA, and could not. So Z is not a perfect indicator. Perhaps Z availability is necessary for SAUA availability, but not sufficient.

I think I agree about Z. Personally I think it's I and X, and not either by itself. Have not had chance to investigate more for myself last year though. And I know opinions vary in this thread.

According to what's been posted by other FT'ers, X isn't even a business class bucket - so I don't know why it would be discussed here.

There are also ~20 data points supplied by more than 10 different FT'ers who were successful in applying SAUA when I=0, so it's just silly at this point to suggest that I fare bucket availability is a necessary condition for SAUA.
