Well thanks all for the updates and the heads-up that it was available again. Thankfully it was just in time for my needs.
I burned the last of my Aeroplan points on J on LX YUL-ZRH-DUB. Probably could have gotten a better value somewhere exotic but this is what I needed and I think a pretty good use of the miles.
I feel like not having any Aeroplan miles left is a kind of freedom. It's one less account I need to worry about expiring or getting devalued away and given the news...
