Pros: "they gave me the special food"
Pros: "Boarding was smooth"
Cons: "More entertainment choices"
Pros: "The crew was very attentive"
Cons: "As much as the flight was truly very good and the crew very friendly and helpful as much as the equipment (airplane, seats, entertainment) really shabby and certainly not worth the the 2500,00 $ I paid for a better seat. I could of flown with Air transat and get better than I got with Air Canada. I feel it was rip off. Quality - price not there . Please give your crew a better uniform. The ones they wear now is very sad and oldish looking. If I think this and am 67 years old, imagine what the younger generation thinks."
Pros: "Everything was perfect on the flight. The service, the food and the crew."
Cons: "Seats are a bit small. Not very comfortable and touch screen of entertainment system was slow."
Pros: "Zone boarding"
Cons: "Very hot terminal quite sweaty"
Cons: "Lack of communication. Crew was unattentitive and seemed to not know protocol or appear to have things under the control."
Pros: "I was first in zone three to enter the craft. Still overhead bins!!"
Cons: "Worrying about overhead bins!"
Pros: "The seating was good and the pilot was friendly."
Cons: "There was not a good movie selection and there was not a lot of information regarding the altitude and there was not very much warning during turbulence."
Pros: "Had to cancel due to flooding at my house. Air Canada was super kind and offered me a credit. Thank you!"
Pros: "Where do i start? It’s a short flight to be sure but air canada planes never feel like many Other airlines’ mini planes or puddle jumpers. they seem new, spacious, seat back Entertainemnt, just great. Also, there is no scrimping on Service. How many Delta or united or American flights have i taken on this route only to be told “coffee or water” and sometimes no coffee “the flight is too short”. Nonsense! Granted I was in business, but I had a full hot breakfast served and a full array of beverages offered. It AC can do it, everyone can. The flight attendant was lovely."
Cons: "The flight was too short :)"
Cons: "Food was not good. Just filling. Crew was not polite when I asked for more water"
Pros: "On time,good boarding."
Cons: "Out of food to buy for dinner."
Cons: "Delayed for almost 2hrs"
Pros: "Boarding was easy"
Cons: "This was a +10 hour trans Atlantic flight. We walked on and immediately noticed there were no TV screens. I expected that the crew would be handing out portable screens instead which would have been ok but pretty inconvenient. This was not the case. We asked the crew and were told that to have entertainment for the flight we would have to download the Air Canada flight into our OWN devices and connect to the airplane wifi. They also explained that you can't download the app while connected to the airplane wifi so anyone who wanted entertainment had to scramble to download the app while we were still on the ground and Use cellular data! at this point 300 people were either panicking because they didn't have a personal device with them, didn't have a charger for their device and so would have power issues or were forced to use up roaming data because they had non Canadian phone plans!!! At the very least staff should have told passengers about this setup while they were waiting at the gate, so that people would have time to download the app with airport wifi! add to all this the fact that the app was extremely low quality and the options for movies/show were disappointingly dated and limited. This was not officially a cheap low cost flight for my family but the service we got certainly would categorize it as such. Very disappointed."
Pros: "The counter assistant was very, very nice."
Cons: "It is good that the flight was very short. The seats were crammed together and the plane was very small. I felt like I was in a sardine can."
Cons: "No entertainment no snacks no checked in luggage. You have to pay to rent iPad to watch inflight movies as pay for earphones. Air Canada has become a premium priced airline with extra low cost /no frills service. Sad and disappointing. Last time I am flying with AC. Rather book cheaper airlines and know what to expect than pay a premium and get even less than the low cost option. Boarding staff was rude pushing people etc"
Pros: "the pilot did a great job. the crew was nice."
Cons: "It was interesting to me that the plane used for a 4 hour flight (this one) was smaller than a plane used for a 1hr flight. I was uncomfortable the entire time. this was a redeye flight, departing at midnight. the cabin lights stayed on for the first hour making it impossible to dose off. we were given a 'snack' of a disgusting chicken wrap slathered in mayo. it was inedible. oh, and accompanied by a large kitkat bar. I mean. Who came up with this combo? there were no screens, no in flight entertainment unless you wanted to run down your phone battery or rent an ipad for $10. I was truly disappointed."
Pros: "Nothing"
Cons: "Flight was delayed for several hours, while the crew assured us it was on the way. When it landed they still said it was being prepped. Then at 10pm or so, they said it was cancelled. Then we waited another hour and a half to speak to representatives and get our hotels. Then another hour to the hotel to go to sleep. Because I had to be back at the airport in 7 hours to catch the next flight. It would have taken me 2 hours to drive to Seattle from Vancouver."
Cons: "See above."
Pros: "Service was on time & staff was friendly and helpful."
Cons: "On the flight back, we had to wait on the airplane for a good hour before we could disembark. But that was due to heavy traffic at the airport and not the fault of the airline."
Pros: "The snack selection is excellent"
Cons: "No complaints"
Cons: "Delay was not explained, gate change was not communicated. Poor communication overall."
Pros: "No issues"
Pros: "Decent movie selection on one of my flights"
Cons: "I had booked my Air Canada trip and had a single stop-over while I switched to a different plane. Both of these planes were Air Canada. I Even though I made it through Customs in the shortest time possible, and back through security, I still managed to narrowly make my second flight. They were final-calling my name and actually taking off earlier than expected. Had I been 2 more minutes late, my flight would probably have taken off. I didn't check any bags either, so had I checked one, I don't think I would have made my second flight."
Pros: "Nice service by flight attendants"
Cons: "Late departure due to mechanical issues."
Cons: "The flight was at least 1/2 late leaving. We were told we had to detour to Toronto to refuel as the plane couldn't hold enough fuel to make it to Los Angles. This caused us to make an unplanned stop which added a total of another 2 3/4 hours to our trip. Really not enough fuel to make a trip we paid for. The cabin was very warm, and we had already eaten our food we brought. Many people missed connections... Not pleased with Air Canada"
Pros: "Alles goed"
Cons: "N/A"
Pros: "Air Canada was kind enough to give us a hotel voucher."
Cons: "The flight was cancelled and we weren't informed until we arrived at the airport. An email was supposedly sent, but I didn't receive it. We had to fly out the next morning and missed half a day of work. Fortunately, we didn't have anything important scheduled."
Pros: "No issues with the plane or service itself but we were stuck waiting for a replacement plan for a late night flight and departed 4 hours after schedule."
Cons: "Old planes,limited food"
Cons: "7 hours flight delay"
Pros: "Lots of leg room and was able to board early"
Cons: "Food not good"
Cons: "I did not take it."
Pros: "Nothing"
Cons: "Everything"
Pros: "It was on time - no delays"
Cons: "Would have liked some snacks along with the drinks offered."
Pros: "Media and staff"
Cons: "No organization for filling planes. Worse than Rome."
Pros: "Cabin crew were really nice."
Cons: "The media selection was minimal."
Pros: "I liked the airport design at Montreal."
Cons: "the whole process in Montreal seemed cold. Not really friendly compared to our domestic flight from Los Angeles to Montreal. The crew weren't very friendly at all. It's as if we were bothering them to ask a question or for them to give a smile once in a while."
Pros: "Fast flight"
Cons: "No leg room Overbooked Bad choice of movies"
Cons: "There was little seating space. I was unable to fully recline back because the person sitting behind me was too tall. Also had broken/uneven food tray."
Cons: "put on stand by, while this was a non required stop over to Brussels."
Pros: "The entertainment selection was decent."
Cons: "Pretty much everything was a bad experience from start to finish. The flight was delayed a half an hour which is fine and can be understandable. The space in the seats was almost criminal for an 8 hour flight. Pretty the equivalent of having people shoulder to shoulder. Impossible to try and sleep on an overnight flight. During mid flight I noticed that I had a lot of trouble breathing and thought it was just me. My wife said the same thing to me and someone on the flight needed medical assistance for oxygen. It was extremely hot the whole flight with no ability to control the air flow which made it even worse. The entertainment selection was good however the device was almost unsable because it was very laggy and it wouldn't select what you wanted. It was easily the worst experience I had and I only really went into some of the details. Having trouble breathing was by far the worst part and I couldn't believe it. My flight back was glaringly better so I'm perplexed by why this was so bad."
Pros: "Comfortable flight and attentive crew."
Cons: "Other than delays and gate changes, flight was fine."
Cons: "Captain's announcements were inaudible from the wing seats. Seats very cramped - I'm only 5 feet tall and barely had room for my legs. Also, unable to see safety demonstration as the seat backs were too tall for a short person to see anything but the back of the seat in front of me."
Cons: "Flight was delayed 40 minutes."
Pros: "Boarded and arrived on time."
Cons: "Too much waiting at Toronto airport"
Cons: "My tv didn't work"
Cons: "No free meal on 6 hours flight, small plane, chanel gates..."
Pros: "Flight crew including cockpit were kind, courteous, professional, appreciative and much appreciated."
Cons: "Ground crew - grouchy, uncooperative and down right unprofessional!!"
Pros: "Great short flight"
Cons: "Nothing"
