Thanks for giving a beer to everyone in the seat infront of me and then telling me that I can’t have one because they are going to land. I guess I need to pay for a seat and then pick one in the very front of the plane

Thanks for giving a beer to everyone in the seat infront of me and then telling me that I can’t have one because they are going to land. I guess I need to pay for a seat and then pick one in the very front of the plane

The flight was delayed by more than one hour. The terminal was consequently overcrowded and hot. We lost our car reservation and hit rush hour traffic in Boston, which added two hours stuck in traffic to our trip.

Awesome, the whole way through. Thank you, this is the new Canadian Airline benchmark.

We were given a complimentary seat upgrade which was so unexpected but so lovely!

Porter was excellent. Boarding was a breeze. The seats were a little uncomfortably but the overall trip was excellent.

Only packaged snacks were served. It was a flight at lunchtime and a hot meal would have been a great.

Reserve check-in was very slow compared to regular check-in. Internet was slow

Lavatories broke with an hour to go. At least we were on time.

Chaotic boarding, but mostly my issues are with Toronto airport

Flight delayed by half hour, causing rush to get to connecting flight in Toronto Pearson which doesn’t have good flow for managing immigration check and connections.

Not enough room between rows and food was gross. $160 baggage charge?! Never again.

Waited for our plane from HNL so we didn't miss connection. AMAZING Service for that, then really clean plane. Nice airline attendants.

Excellent staff helping my 96 year old senior promptly with her oxygen needs

Basics were there, but a 5:15 flight with almost no food ans no entertainment, it is quite long.

Moody attendants that can barely look up at the passengers. I’m all for people having an off day, but you can tell some Untied Airlines Employees have lost their zeal for their jobs

Some of the issues with my UA flight to a connecting flight: United said the SF to Frankfurt flight was getting late making us miss 10:50 flight and could only put us on a flight that left at 4:15 PM from biz to coach. then they canceled the ticket on the connecting flight. I didn’t have a seat, etc., etc., and over an hour dealing with UNITED blaming Lufthansa and Lufthansa pointing to UNITED. The flight itself was fine (food sucked) and we landed in time that I could’ve made the 1050 flight. but the LH gate agent said I couldn’t get on because United issued the ticket and only they could change tix back. Gave up and wasted the next five hours plus of our vacation and ended up being totally wiped out by the time we reached the hotel.

Check-in was a little confusing. I paid for extra luggage, but when i checked in the system didnt seem to know. Arrived in Paris early after a late departure. Luggage arrived on the same flight with no apparent damage.

Flight was quite late as there was no pilot Crew is usually excellent, this flight not as good as usual there were more mistakes, slower and less friendly service But honestly the aircraft was too cramped and uncomfortable for a 4 hour flying get so, do to the aircraft liability the very best you could ever do is mediocre.

It was so uncomfortable for 14 straight hours it was torture

Absolute disaster. Rude, uncooperative staff. Staff ignores and pretends you don’t exist when you are asking them a question. Erroneous departure gate and baggage claim information. Equipment not working for purchase of drinks. Overly expensive baggage check-in fees. Overly crowded. Dirty airplane. Passengers coughing incessantly as if they were being gassed. Circled airport in flight several times and waited on the tarmac for 1.5 hours. The worst experience ever. Consider another industry. The travel industry is not for you.

Your staff on the flight back to Calgary were very friendly and efficient .

The big lady was sitting right next to me and the button to recline my seat was blocked by her huge arm. No power outlet for chargers. No inflight Wi-Fi movies

Trip was uneventful which is good. Boarding took a long time due to many disabled/elderly requiring assistance which again is fine. Landing and take off were excellent. Food and entertainment were as expected, bring your own if you have preferences otherwise you get what you get.

Check in agent was good, stewardess was unfriendly and certainly did not have the care of the passengers in mind Spent the whole time on her phone

The flight was on time - which is good. But pretty much every other aspect of the experience was bad. They charged 55$ for a carry on bag!

Flight was old and the seats were not comfortable at all. They made me pay 55$ to take my carry-on bag onboard.

Wasn’t able to purchase wifi for entertainment so the flight was long

It was a swoop flight at a west jetfare… the plane was literally a swoop branded plane.. I pay extra to NOT fly the budget carriers like swoop and flair so needless to say I was annoyed when both my outgoing and return flight were on swoop planes.

Okay but not like typical first or business class. On domestic airlines

I liked the kindness of the check in counter crew, the flexibility with changing seats and the comfort. Better free drink selection would have been good but it wasn't a long flight.

Hated charging my devices. The location of the outlet was inconvenient. And no USB connection. So outdated.

They were so kind and helpful and they even brought an item of mine that I forgot on the plane!!

Flight took off little late and landed back at YVR after an hour without informing a reason to the passengers. Also, second time also got late but an hour to take off. Therefore, I had to change my plans during due to delay in landing to SFO roughly about 6 to 7 hours.

. Crew was professional and friendly. Food could have been hotter

Our flight AC 567 was delayed by almost 6 hrs due to mechanical falure

Terrible. They cancelled our flight the night before. Please give me a call to discuss.

Very pleasant crew! Good entertainment options. Water wasn’t working in the bathrooms, but they were able to fix it. Just had to stand with sticky soap hands for 20min….

Some help when I asked but everything was so confusing to figure out otherwise. More clarity to direct through procedures needed!

I missed this flight because the previous flight was late.

This is the first and the last time I ever fly Air Canada. The seats were extremely uncomfortable, no leg room. My back was throbbing by the time the flight was over. I payed both flights up and back for internet and both times had trouble connecting all while the clock was ticking on my payed subscription. Here's the worst part which I have never experienced on a flight before. the flight attendant would walk down the aisle with the drink cart and only give out drinks to selected passengers. This was not a big plane, there were not that many passengers! We were totally ignored, I had to ask three times for my husband to get a drink. My son and his girlfriend were sitting across the isle from us and received a snack but we were never offered a snack or anything. My son's girlfriend had children sitting behind her who were continually kicking her seat the entire flight. I have never wrote a negative review for an airline before but after spending my money for four seats I was extremely disappointed in your service.
