It was fine. There were a couple of mechanical delays prior to takeoff but it was overall a quick and pleasant flight.

It was fine. There were a couple of mechanical delays prior to takeoff but it was overall a quick and pleasant flight.

Mixed experienced. Nice staff. Spacious 787 better than cramped Airbus, though my seat was broken. The bad: Way overpriced ticket and charged for food despite 6 hr flight.

Air Canada business class used to be among the best among North American airlines, however it has gone downhill since the last time I flew with them. They didn't even offer any drinks prior to takeoff despite having over 30 minutes on the ground for boarding and de-icing. Once we got in the air the service was fine, however the food was lukewarm at best and just okay. The warm bread and spring mix salad was very good at least. My main complaint is they were letting economy guests use our washroom. Presumably because the Max 8 only has one in the rear. However as I was sitting in row 1 I constantly had passengers waiting in line for the toilet.

Very smooth flight and the crew members were very welcoming.

The plane was cramped and dirty. Not enough liquid was served to stave off dehydration.

The speaker flight attendant talked over was way too loud. Hurt my ears -had to take out hearing aids.

Super. Planes were clean. Flights were on time. boarding was smooth. Flight attendants were professional.

ground crew at Casablanca as well as at Montreal was not helpful at all. specially at Montreal airport, very rude .

The flight attendants were lovely - very warm and kind. Really appreciated it.

For boarding, after family with youngsters, you should have 65 and over. Whatever rules, enforce them. It’s frustrating for those who respect them to see aggressive people rush to the gate out of turn…
