Flew on AC649 YQM to YYZ in J on Feb 28 and hot meal was not offered. We all received a smoked salmon plate, similar to what I have received on YOW to YYZ in the past. I recall in the past on flights of that duration (2 hours 32 minutes) receiving a hot meal with salad, choice of entree, bread and dessert. Does anyone know if they have changed the flight duration thresholds for meal offerings?
