If you do not find enough space for your personal belongs( bags or luggage), you can ask the crew for help. They are kindly and friendly, and they can help you.
ElizabethFlew with Air CanadaSFO-YYZMay 2024
When delayed happened I would suggest for the crew to let passengers board in and just wait for the one crew missing to arrive and joined the crew as soon as crew member arrives other than passengers waiting this helps time consuming . And passenger not rushing for connecting flight.

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.

Great flight and crew. Food isn't free and neither are headphones...

We were in economy class but paid for option Plus which offer you an extra snack after take off, free earplugs & blanket. The crew were very attentive. The comfort however wasn’t great, hard to be comfortable in such restraint place. Wasn’t able to sleep through out the 7hrs flight and was exhausted upon arrival.

The flights were on time and the crew was friendly and helpful. The food was ok. The seats were quite cramped and if the seat in front was tipped back there was very very little room. The entertainment was only on your own device and there was no usb charging

Boarding and staff were excellent. The food was ok. Very cramped seating. No existent entertainment other than on iPhone over wifi with poor choices of movie or shows. Bring your own entertainment. Nowhere to charge your phone

Delay was not properly communicated. Service, plane, value of ticker were all great.

Excellent service and food in the Club Class. Warmly recommend. Much better than AC.

My new suitcase got busted when I arrived at Toronto , two of the wheels are broken and can no longer be used , I am very disappointed over this situation but the flight and service was awesome .

From what I saw there was no entertainment. Similar to my flight to London, I personally would like the attendants to be more interactive during the flight.

Air Transat left my luggage back in Montreal and it took them 5 DAYS to get it to Venice. Luckily I was still in town, or else their option was to send my luggage back to my house in CANADA. What a joke! Oh, and I had to find a way to go get it at the airport in Venice, they needed 72 hours more to get it to where I was staying.

I was pleasantly surprised. I booked the "club class" which was basically like Domestic First Class. The service was superior. Food was pretty good. Seats and cabin were comfortable. For the price I paid, I was very pleased.

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.

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

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….

I did not appreciate being scolded by the captain himself, and being told my dog could die, in front of my daughter.

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.

Flight was canceled 2 hours ahead. Just as I arrived at the airport

It’s very good.. keep up the good job!!! Thank U.

The flight was canceled. We only found out at the airport. We had to book another flight which cost us more then the whole trip booked through Kayak. Lynx took our email and was supposed to write us with an alternate flight. We never received an email. They talked about reimbursement which was to be explained in the email (which we never received).

The online system for Lynx air to pay for additional baggage is not satisfactory. I was charged 100+$ for my suitcase when I tried to explain that the online payment was not functional using the app and showed screenshots of the same. In the end I gave up and paid and went ahead.

No snacks, just water.... could have been better. The actual flight was good.

Flight delayed by 4 hours but no communication. With passengers until after the posted departure time became apparent the flight was not going to board even close to on time.

Flight was sent canceled. The absolute most useless staff I have ever witnessed. Utterly careless - literally could not care less. 100% never using this airline again.

Poor communication at the check in counter and boarding gates.

Other then the screaming baby the flight was fine, nothing special

Check in experience was smooth, and the flight attendants were courteous and friendly. Very positive experience overall, thank you all!

Flight arrived late but other than that everything else okay

Great price for a new plane. Only offered water which we knew.
