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.

The plane was clean. The staff was excellent. The flight attendants were very good. Enjoyable flight. Overall. The seats in the back are too small but, will always be.

Overall good flight. The pilots were excellent. It was a nice flight, but the seats were a little uncomfortable.

There was no air on the plane and it was very hot.

Flight crew was amazing! I don't like that the Polaris seats are side-by-side.

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

Flight was 3 1/2 hour delayed with no credit or meal vouchers

Smoothly flight, pleasant flight attendants. I wish there were better food choices.

Booked a united Air flight with option to pick seat , then found out was on an Air Canada flight with assigned seat , then they wanted a several dollar charge for some 25 cent value entertainment listening ear device

Pleasant service from the crew. Arrived early. Efficient boarding and deplaning. Great job!

The free snack options are pretty pitiful for a 2.40h flight.

The people are great! The trip to Japan is simply never ending!!! Not the problem of the airlines, though.

Friendlier staff who are nice to the elderly who need assistance

Everything went very smoothly and the staff was courteous and friendly. I was really happy and pleased with how well the plane was flown because the departure, descent and landing were really smooth with no sudden drops. The plane’s interior was clean and nice and new in appearance.

Air Canada is the best company I’ve ever flown with. If I had the money, I would only fly with them.

Terrible - flight was flagged for fraudulent payment from being booked via Kayak. Requested to rebook with original credit card or provide new payment. Air Canada stay at JFK did not know how to process new payment. Had to fly from La Guardia 2 1/2 hours later instead with Air Canada.

It was a small plane and difficult to put my carry-on bag in the overhead compartment. The crew was awesome and boarding was good.

I liked Air Canada crew, very profession, the food was excellent. The boarding was fast but has room for improvement. My monitor screen wasn't working at all so I had no entertainment.

Air Canada seats do not have much room compared to other airlines I’ve traveled with. Also, the lack of free WiFi is a negative. All airlines need to be better about this.

i know it's complimentary - but they didn't have enough snack for all the passengers. there was no entertainment or available WiFi

Very poor.!!! They cancelled our flight and rebooked us with very little time to catch the flight. Our luggage was lost. As of now we do not have it yet. No clothes to change on the second day of vacation.

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.
