It's a CRA so limited # seats and no kitchen ( last time no coffee, water issues ) so not exactly a great "J" experience, but compared to regular CRA seat well worth it.

Flown it twice earlier in the year before they pulled at a route (YEG-YYZ-IAH is now a no go, but I can do IAH-YYZ-YEG return, go figure )

No issues getting e Upgrade on late afternoon/evening flight Monday or Tuesday out of YYZ
