Horrific, we bought our tickets 6 months in advance and paid extra for specific seats close to the front. There was an equipment change to a larger plane ( more seats), identical configuration, you would believe they could honor the seats we purchased. Unfortunately not, and they sent multiple alerts from 11pm to 2am, keeping us up all night. Eventually my husband was moved to the back of the plane with 40 rows, 10seats wide, 🟰 400 people ahead of him to deplane. ( we had a time constraint we had to catch on landing) I don’t mind a middle seat if it is my husband or travel partner, but if I thought there would ever be a chance we would be separated. I would choose an isle. There was no one we could contact as we were at sea, with no cell service. Once docked, We went to the airport an extra hour early, no help at all Air Canada check in counter told us we don’t work for air Canada, call Toronto. Horrible service all around. When you pay for seat selection, don’t count on it with Air Canada. ☹️
Flight was delayed for almost 3 hours. Communication of gate change was poor. Email and screen said one gate and it was a different gate from that. Gate changed first to 64 B and then to 64 C. Originally it was 68B. 64C was not communicated properly!
Didn't like that we couldn't be seated together or seated away from the stinking toilets or check in on line. All rather poor.
Flight attendants were great. The food I ordered was actually pretty good, and I appreciate the non-tuna snack. That long of a flight in those chairs is just brutal.
This was a red eye return, so I doubt there would be anyway to make it better. Other than adding beds.
They changed my flight twice. The 2nd time they changed it they did so the day before the scheduled departure and replaced the lie flat seat in a 777 to a 737. I paid extra to be in the 777 only for them to change it. Then the departure was delayed twice. The connecting flight was also delayed.
Direct nonstop flight was great. Flight was delayed and the crew announced a 2h delay on the sound system. 30 min or so later I hear my name on the sound system for immediate board. Several other passangers were late too. Reason: The crew incorrectly announced a 2h delay when in reality they meant a new boarding time at 2pm.
Flight was on time early arrival better entertainment good staff.everything was excellent
I don’t think there was entertainment? No mention of it. It was a good flight. Only complaint was my seat cushion was not attached and kept slipping.
