At this juncture you should ask yourself if you are satisfied with this "compensation" of a 20% off coupon on AC flights. Keep in mind most of these coupons have an expiry date so you'll need to see if you'll be paying out of pocket for a future AC flight say in the next 12 months. One thing you may want to try doing is getting AC to rebook that segment at a different time that provides J availability. This may also be beneficial to you, since you'd be able to use the MLL at YYZ which has showers that will allow you to freshen up after the long endeavour you've had so far! It is my understanding that in situations like these, AC has been known to open up award availability, particularly if the flight is on their own metal. Having flown AC Rogue in Y across the puddle to MAN, I was not satisfied at all with my seat. I had a sore rear after maybe 45 minutes in that seat. While I cannot comment on what the "hard" product would be like on your 3 hour trek to YYT given it's a different aircraft (A321 vs 767), Rogue Y service has left much to be desired. In fact I believe several people on this forum swear they'd never fly Rogue domestically, even for treks as short as YQB > YYZ.

Safe Travels,
