Airline reviews

Pros: "Fast flight with no delays"
Cons: "Very old entertainment unit, slow touch screen, confusing interface. Very tight seats that were not very padded. Overall uncomfortable"

Pros: "As a professional musician, flying with my viola is one of the most nerve wracking experiences, as if it is forced to be checked due to insufficient room for overhead baggage, it could be completely destroyed. As stated in Air Canada's online policy, passengers traveling with musical instruments that fit as carry on baggage are allowed to change to earlier boarding zones. After approaching a staff member with my viola, I wasn't simply assigned an earlier zone, but rather I was allowed to board first. On this principle alone I will be flying Air Canada again. Thank you!!!"

Pros: "Loved the staff. Very friendly. Planes were clean and most of all, got to me my destination. On time!"

Cons: "The flight was delayed. Boarding was chaotic. Flight itself was choppy."

Pros: "Good price"
Cons: "Horrible customer care"

Pros: "Delays"
Cons: "Delays"

Cons: "They cancelled the flight after we were on the runway."

Pros: "Everthing was smooth and on time"
Cons: "Nothing specific"

Pros: "The crew was amazing"
Cons: "Nothing"

Pros: "Left on time, arrived on time."

Pros: "Nothing"
Cons: "The airline failed to mention transit visa rules. Really poor customer service. Irrespective of what time of the day you call, the average wait time is 30 min. Who can wait for 30 min to receive his/her call. That's stupid for a premium air line. Even when someone answered they failed to provide a solution and were unsympathetic to my cause"

Cons: "Good"

Pros: "Not much"
Cons: "The crew member wasnt letting me on my connecting flight which i was late for because of delays Air canada caused for the previous flight. Even though my connection was grounded for an additional hour. Worst airline ive ever been on."

Cons: "2 and a half hour delay"

Pros: "Everyone was nice and the seating area had room."

Pros: "Checking our luggage at the gate and how courteous everyone was Maureen"
Cons: "paying for extra seats was fine but our zone was the last to call. Maureen"

Pros: "Our flight was delayed about an hour and a half because of earlier delays in the day and the ground crew and pilot kept us fully informed of the situations as they evolved. Because of the timely updates I did not hear one person complain in my earshot range. Apart from the delay the service was great, as always."

Cons: "After paying for a business One-Way.. the flight was canceled abruptly without any forewarning. There was the a line of 50-75 ppl with one attendant working. It took me nearly 3 hours to get anyone's attention, and finally told i was 'lucky' to get on a flight the next morning, after missing a Wedding dinner. I was also forced to pay 2x cab rides to the airport. Thanks Air Canada"

Pros: "Leg room."
Cons: "A little ineptitude with boarding and the flight was delayed with confusion. Some of the staff were not aware of what exactly was going on."

Pros: "Shorter flight than expected. Snacks. The baby beside me didn't cry for once"
Cons: "My tv had no sound."

Cons: "LONG DELETED !!!!!!!!!!!!!!"

Pros: "Service was good"
Cons: "Flight got delayed"

Pros: "Smooth Flight, zero turbulence."
Cons: "The categories food and entertainment do not apply for this trip since it was a very shirt trip from NYC to Montreal Food and Entertainment is not available."

Cons: "To start, this flight was overbooked which I understand is a perfectly normal aspect of flying. However, the seats on this airline were so close to one another my legs were hitting the seat in front of me. I'm a thin 6' tall man, and I was uncomfortable the entire time. I've flown Air Canada many times but I've never experienced such a cramped seating experience with them. It was as if they added an extra five rows to the plane."

Cons: "Long time till take off."

Pros: "Things were very good. Staff was freindly."
Cons: "The internet wasn't working but not a problem for a 1 hour flight."

Pros: "it was on time landed a few minutes early stewerdess were very nice"

Cons: "2 hour delay"

Cons: "They charged us 25 dollars for a carry on bag which was unfair. They didn't charge anyone else. When I came back I was not charged. I would like a refund. The people were very rude! I take that bag on trips weekly. I should have not been charged."

Pros: "Everyone was very nice"
Cons: "When I went to Check in there was alot of problems with the process on line By the time I was able to enter my information the session had timed out. It was so frustrating because I had to wait 51 minutes for an Air Canada representative to confirm I had checked in eventhough I didn't have my boarding pass on my I5 phone. I really like your planes and service providers,but your website is awful."

Cons: "The Toronto airport was ill-equipped for an international transfer. I barely made it despite a 90 minute layover. Air Canada was OK, not great."

Cons: "Very long line to get to security"

Pros: "Free snack"

Pros: "The fact that I was rebooked immediately to my new flight AC-DC 705 at 8:50 am by two wonderful ladies at La guardia airport who comforted then boarded me unto a flight due to the fact that I missed my original flight. This occured due to the Airport being Unorganized! As I had checked in well before 3 hours and was on time for my original flight at 8:30 am."
Cons: "The airport was extremely packed, Unorganized and not well staffed. What I hated is that when I arrived at my original gate A7 the gentleman who boarded my original flight was unprofessional, rude, basically ignored me and said "You missed your flight !" Not even taking the time to listen to my situation or guide me in my next steps of acquiring a new flight to go to my classes and home in Toronto!"

Pros: "Decent leg room"
Cons: "Everyone confused about the aisle seats. Took much longer to find proper row."

Pros: "The flight attendants was very curtesous."

Cons: "This site allowed me to book a CANCELED flight. I found out 20 hours before my scheduled flight that I was on an 11:20pm flight not a 7pm flight."

Cons: "I was upset that my flight was cancelled one day before the flight day. I contacted Air Canada but they should have tried to contact me as soon as the cancellation."

Pros: "TVs in each head rest with movies."
Cons: "No communication or care. Sat on plane in Toronto for 4hrs - no offer of beverage or snack. To announce flight cancelled. 90% of flights going same location was cancelled from gate. No reason to assume our flight would have special us president clearance to fly. And doesn't take 4hrs to figure that out. Then was not giving any assistance or comms on new flight. When called told best chance is 2 days for flight and was not providing any hotel voucher. We ended up driving from Toronto to NYC. We were irate!!!!!"

Cons: "I had 21Inch suitcase. but who helped me check in staff , he said my suitcase looks littlebit big charge me seccond luggage fee $35.... my suitcase 21Inch..it is cabin size...even I didnt use extendingzipper, when I see other people suitcase same size with my suit case or more ticker what I got more mad is my new suitcase got scratched, cracked. I paid $35 . I got broken suitcase ..no reson to do that .it is firsttime I used that... also flight is delayed 2 hours both time .this is understand. .. but I stil got mad, don't understand that silly staff. I regret I couldn't complained and choose aircanada. Also he never smile to customers not kind at all seems doesn't wanna work. From that , Whenever take flight to short distance I will use westjet or other one."

Pros: "Great flight, service was excellent, will choose Air Canada for my next trip to the Orient!"
