The return trip was a customer service disaster. American Airlines needs an overhaul of how they treat their customers.

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

Delay. Flight was delayed in Washington.knew that connection was impossible as not enough time to switch terminals. The steward would not let me stay the night. So forced to Dallas.late night, after 10pm.hotel checkin was one hour. Passengers lined up only one girl to checkin at comfort inn. No food availability at that time. Had to leave early at 6:30 am to catch a flight at 8:45. Stressfull.

Boarding and crew were great. Everything was. On time. The 737 was Incredibly Uncomfortable!! Too tight in seat area for one, but, the real problem was that the seats were AWFUL. After an 8 hour flight from Dallas to Madrid my lower back was miserable and I am fit: I never have back problems. It took 2 days to recover. Honestly I can’t recommend AA for long distance flights. Plus for a $1200+ ticket they wanted $30 for 2 hours of internet. Thank you for listening.

1st flight was delayed because of broken radio, missed connection but they got us on very next plane 1 hr later. Return flights were both delayed by 1 hr each. Crews were fine. Planes ok, but had to check carry ons.

First off, I never complained so it is not the crews fault. The lady to my left did not respect my seat whatsoever. She was too big to lower the armrest and basically sat on me the entire flight. She was against the window. I was in a middle seat. For future reference, American, please make sure the armrest will lower or get someone a larger seat/2 seats.

Midway thru the 2 hour flight the entertainment system just stopped. I could get the map, but the movie and tv stopped playing. It seemed to be an old plane so perhaps it only a rare occurrence.

less delays; there was an hour+ delay on both flights. self serve check in kiosks weren't available for British Airways flights

The flight was delayed for over three hours due to mechanical issues.

The flight was delayed multiple times. I had to buy a new tickets (4 tickets) for my family for a total of $5200 cnd And missed thanks giving with our family. Very very poor and disappointing service.

Crew was very respectful and ready to serve. Much better than before.

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
