It's only 1 credit to Eupgrade since I'm booked into Y so I figure, why not. Apparently it cannot be done.

The ticket itself is AC issued and the flight is AC8557 (no codeshare) but the fare basis on the bound is an LH filled fare basis. I was told on the phone that because of this, the flight cannot be eupgraded. This makes no sense to me because even partner bookings can be eupgraded so long as the flight number is an AC flight number. This is an AC issued ticket!

The agent on the phone was pretty mystified himself and apparently so was his help desk. The only thing he could suggest was to submit a customer relations complaint through the website and see if it gets anywhere.

Has anyone run into something like this before? Is there any policy that someone is aware of that actually states this flight wouldn't be upgradeable?
