My buddy and I got a text message and an email before our YUL-CUN flight last week. Both bought on points, no status I was in (Rouge J) He was in Y. Both TD Visa AP.
The thing is they said: "Your flight in full" and it was one of the lightest loads I have been on in a long time. I was 1/1 booked in J and counter at least 100 empty seats in Y.
