For example, to upgrade Air Canada Y/B fares, you need P space available, but it books you into R when it's confirmed.

I know for a fact that there was no O space on my flight when I upgraded mine, because it was the first thing I checked too.
Star Alliance upgrades usually require full fare Y/J for upgrades. I wonder if Z on ANA was included by mistake.
