Cabin was roomy enough to easily slide my carry on under the seat in front of me!

Cabin was roomy enough to easily slide my carry on under the seat in front of me!

On time arrivals and departures. Gate boarding notices could be better if displayed on monitor.

Everything was fine. Flight boarded and departed on time. Seating was spacious enough for my carryon to fit under the seat in front of me. No complaints at all. Flight even arrived early.

We kept being told that the flight was full and that all overhead compartments were full and therefore had to check in our hand luggage. We were some of the last people to board and noticed that there was still sufficient space in the overhead compartments. We were obliged to check in hand luggage when there was space and so had to wait at luggage retrieval which took a while to then noticed damage to our luggage - not a great experience!

We were not offered anything to drink in business class during the boarding process.

When I'm on a 5hr 22 minute flight I expect food to be purchased. Especially when American makes a very tight connection time where u have to run to make the long flight. Chips and nuts are unacceptable and being told you should be in first class to get a meal is also unacceptable. I didn't change the flight times American Airlines did.

Flight was delayed taking off over 2 hours. Original plane was taken out of service and replaced. They didn’t tell us they were replacing plane until after original takeoff time had past. No power on new plane to charge devices. When eventually landing at destination no gate was available waited 1 hour for new gate. No Americans finest hour.

Crew professional. Easy bag drop off. On time. Good entertainment.

I liked everything. Except that my neck was hurting on the seat. I couldn't sleep.

Good experience but the snacks are not gluten free, so I cannot eat them.

Boarding was challenging as we had to use the stairs from the tarmac. Stairs are okay but a roller bag makes it challenging.

Ensure prepaid food arrangements are appropriately understood by flight crew of who purchased and who did not

All was fine. Weather was a bit stormy, but nothing kayak can do about that! 😊

I paid for a comfort class seat and was seated in economy.

Once again our Air Canada flight was delayed! I'm hopeful competition arrives with other airlines soon and maybe they will make a better effort to be on time!

My plane was cancelled and had to be rebook for the evening was not happy.

The flight was cancelled and we had to rebook on Porter to make our cruise the next day. Air Canada has not compensated. We won’t be flying with them again. This is the second time this has happened. Also the return flight was delayed 2 hours who knows why.

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.

Separated me and my wife and wife’s sister in far apart different seats even though I booked them all together. Just scams after scams to make us pay more. Worst airline

Very smooth flight and the crew members were very welcoming.
