Can you please process refund. Mum died and dad went to Pakistan to bury her after cancelling flight.

All was good, the only thing was it didn't run on time.

Great meal. Best seats ever! They need to teach other airlines how to do that.

The staff and crew on board were excellent. Business class however, was very weird. I thought we would have individual pods, but the way it was set up was unexpected. Not very private and If you wanted to lay down, you had to have an entire bed made up for you by the crew, rather than how Delta one works where you could just lie down whenever you feel like it. It was a 16 hour flight. I chose not to have my bed made, and that turned out to be a good idea because everybody who had their bed made had to wait for the crew to roll up their mattresses. So strange!

Food was not good. We asked for Muslim food and it was weird tasteless type of boiled veges.

Couldn’t request a vegan meal somehow but I noticed other people getting them

United flight from SFO to PDX was cancelled. I will ask for a refund. Had to book on Alaska

Good food and entertainment options. Great Staff that were all welcoming and caregiving.

The recline on the seat in front of me came back so that I was staring at the top of the man’s head in front of me the whole trip. He refused to bring his seat back up twice every time he was instructed to do so and only relented when he had a tray of good in front of him. And then right back in my lap!!! Horrible man!! I complained to the staff multiple times, but no one would address the issue. Otherwise, it would have been a perfect flight.

There was a snafu with confirming seats at check which left us in limbo for the second leg of our trip. I believe the ANZ app is not well integrated with the systems at the terminal resulting in this disconcerting error.

Great crew. Very comfortable business seats with nice bedding. Good food. We were delayed to let late passengers on the flight, but otherwise great experience.

lounge was the highlight - seats weren't that comfortable - it was a full flight but no complaints

Cut off carry ons, had to check, got on and there was plenty of bin space. Disappointing.

The food at Admirals Club was really great Pijamas were a nice feature The flight attendant was very nice and great attitude The aa.com does not work well specially internet service Overall a very good flight .

Delayed 4 hours from Charlotte to Nashville. Could have driven there faster. Information provided by AA was sparse.

Flight a little late. Entertainment system didn’t work for first hour. Toilets dirty after 2 hours. Is there no one assigned to clean them?

I did like the employee's, they are very friendly and all smiled most of the time, Overall, from checking in bags to getting on plane, not enough employees to be able to get all on the plane, therefore I was not able to get on the plane, due to no one wea there for me to check in my bag, so I decided to go thru the security point and by the time they were done with my bags, I was told that my bag cannot be checked in, and then found out that the lady that does the check in was boarding the customers onto the plane, she said that she was going back and fourth, there for was not able to get on the plane, which changed all my flights by the time I got to Dallas, I was on standby 3 times, and wasn't sure about being able to get on the fourth plane, so ended up buying another plane ticket, so I could make my destination on time.

Not sure about entertainment as I didn't use any, soay e there should be an NA option on this survey. Otherwise everything was just as it should be. Of course I wish planes were more comfortable and had seats that would tilt back further.

American always delays flight so it stressful getting the next connection

I hate when you book your seats and then they sick in in other seats when you get there. We were to be in row 9 and was moved to the back of the plane and separated our seats. Great start to a trip

Terrible experience! All flights delayed, staff had no idea of what they were doing, and at the end luggage lost for 2 days!

Flight was delayed, I had to put my luggage all the way in the back! They served only a beverage no snack on the way in Air Canada, definitely not a good first impression.

It was an enjoyable flight. I guess the airlines will never go back to catering, they save so much money.

Lovely staff for a short flight! Complimentary wine too made me happy.

5 delays to departure. Finally left 2 hours after scheduled time. Further issues with “paperwork” when we were ready to push away from the gate. Air Canada has a real problem with flights between Montreal and Toronto over the last 24 months. Of my 12 flights, 8 have been delayed or cancelled. With no compensation. I now drive between Toronto and Montreal whenever I can. At least I know I will get there when I planned to.

When we got to the airport for our flight from Chicago to Montreal which was scheduled for 2.00 p.m. they had no record of it and booked us on a flight at 3.30 very disappointing . We also had to pay 50.00 each for a seat. All things considered ,I will never book thru Kayak again. Next time I will only book directly thru Air Canada no second party booking Sue

Terrible crew. Mediocre food. Terrible headphones. No Bluetooth connection for entertainment. Crying babies. Horrible experience.

I am 6'0 and almost no leg room. I am also not a small person, but this was the first time I had a issue with the seat belt. I feel like they should be made a tad bit bigger.

Difficile quand le gate change, les deux fois. Quand on m'a changé les sièges que j' ai réservé, les deux fois. On m'a dit que j'allais être remboursé et rien eu encore

Air Canada continues to disappoint in almost every way. Probably the result of a monopoly, so NO need to improve anything
