I agree with [MENTION=239882]tentseller[/MENTION]’s comment. Upgrade inventory and straight redemption come out of a different bucket, even though they will both ticket in the T(PEY)/U(J) fare class.
I think some of the info on the wiki above might be slightly out of date. There had been quite a few policy changes re: upgrades/redemptions/waitlists in the past few years.
I have always wondered, for airport upgrade redemption, do we require T/U class availability or is it solely governed by unsold/unfilled seats at flight closes.
The odd times I had to wait till the airport to redeem my upgrades (due to no upgrade availability beforehand), it seemed to me that the upgrade clears based on empty seats and not T/U class availability. But I always wonder whether this is the actual policy.
Officially, T/U/Z class availability is required. See

Nevertheless, my experience aligns with yours. I suppose they will just make a seat available in award class if needed at the airport.
