Strange.
I checked in online today as soon as I got the email asking me to. I have both boarding passes now electronically. YOW-YYZ, YYZ-NRT.
However on the AC site I still can press the check in button! I proceeds to a page titled 'Welcome'. Is this normal? I would continue but fear loosing my place in the upgrade line, for whatever that is worth.
My booking reference also shows the upgrade as Waitlisted, and the other YOW-YYZ flight as Eligible. Normal as well after OLCI? When I was doing the OLCI I selected the button marked Upgrade Certificate.
Something feels strange.

The OLCI is designed to allow you to reprint your BP or even remove yourself from the flight if need be. It's behaving normally.
