I watched FRA-YYZ like a hawk on my last mini RTW and basically had it down to what minute in the day it would show up. When it did, I called in to switch and the agent couldn't find it!?!?! Tried another agent and she couldn't either. Tried again the next day and was able to make the change. I don't know what I'm telling you here, other than I'm pretty sure it will open up! I checked every day for weeks and it did.
