You can see the upgrade list by clicking on the Flight Information tab, entering the flight you want to check, and selecting the upgrade list tab on the flight status page that comes up.
No, they are pulled from Z. You cannot view Z anywhere, including Expertflyer. You have to call Copa. Z is used for all classes of upgrades including the instant upgrades for Y,B,M. I don't think they open up anything before the flight, including at the "windows" for elites. So if Z=0 at booking then you wait until day of flight.
You have to call to get the Z information. But if you see I then you will definitely get the upgrade.
UA codeshares show CDZ (and another class). UA codeshare will show 0 for all these business classes buckets unless D>0 booked as Copa flight. I don't know if the Z class you see from UA has any relation to the Copa Z bucket. I think not based on my brief research because then D (Copa) would indicate upgrade availability; my flight was D>0 and I didn't get my instant upgrade.
