This has been the worst experience I’ve ever had. Basically, I lost my round-trip tickets because one of my last names was missing, and you didn’t allow me to correct it. I had to purchase a full ticket again. Once I get home, I will start legal proceedings against you.

This has been the worst experience I’ve ever had. Basically, I lost my round-trip tickets because one of my last names was missing, and you didn’t allow me to correct it. I had to purchase a full ticket again. Once I get home, I will start legal proceedings against you.

The crew were polite and courteous. The Pilot did an excellent landing. It was very smooth and gentle. My only regret is that I was charged twice for my luggage . The attendant gave me no receipt . I didn't realize until I was about to board. How can this be resolved? Thank you.

Very smooth flights Toronto to Rome and return. Crews were great, food was fine but very narrow seats and limited leg room. Aisle seats on our return helped with a bit more space.

YUL AIRPORT is the worst. 1 Hr to Get out of the plane, 1 Hr To Cross the Border. 1Hr waiting to be pick up curbside. Trafic is ubeliveble.

It’s ok just the boarding point is far too far

Check in slow even though completed online check in, there was no bag drop available so had to query for 90mins as only 2 staff on desks.

Flying to a far away destination is a miracle in itself, so please take these with a grain of salt. The seats are a bit tired, and need a freshen up. The entertainment could be a bit newer, especially with all services available now. The food really is where we need help. But again, flying is a privilege, so all is good.

Not so much porter it's your site! Not good

They are a sister company with Air Transat and the two companies do not work well together. If you have any issues the two companies will blame each other and you will miss your flights. The help line does not help

Never book through a third party. Book through Air transats website. Terrible process to get help and many issues happen with them and sister companies because half the flights you book with them aren’t even through air transat.

Overall, it was good. I was seating next to a wonderful lady and did not notice how time flew. Thanks

My flight was delayed about 1 1/2 hours in Chicago, but other then that it was a good flight.

The experience was great, the crew was very polite and hospitable. I will definitely make if my go to airlines.

It was all good flight was on time, service was good I enjoyed a few movies and everything was smooth

Efficient, calm when things were delayed and kept us regularly informed of what was happening.

Airbus plane, nice and polite staff, entertainment even as it was a short flight.

Very nice and clean plane. Transit time between flights was tight though

Our flights got changed from United to Air Canada and our purchased seats did not get transferred so we had to pay for seats twice. I brought it up with Air Canada and they stated I had to go back and chase it with United. The united seats were $21 Canadian each and Air Canada were $56 each so we have paid $77 for each seat. Very unhappy

So far so good but food and entertainment are not available for this flight

Plane temperature was comfortable (not to hot) when boarding and waiting for takeoff.

The flight was on time and crew were nice, seats were tight and there was entertainment available

Good service, friendly staff. Food was average for airlines and the seats were small.

Worst flight ever. I was suppose to have a 3 1/2 hour layover in Chicago but got to the gate 4 minutes before boarding.

No food offered, just chips. Crew was no nice. I had to Stand up and ask for a drink. Even for a midnight flight I have had better experiences from another airlines.

The plane was broken so we had to change planes.

The AA app really sucks ... Every flight & connecting flights were delayed over 30 mins. One connecting flight on American Eagle said it was delayed in its arrival ... when it was actually parked across from the gate for over 1 hr before they pulled it to the gate. Seats in the economy/ main cabin are packed together like sardines ... no leg room.

A cookie and a soda, packed like sardines, will never be a positive experience. Also, boarded a 5:30 flight at 7:45pm

They cancelled my flight and downgraded me to economy and only gave me $250 for the downgrade

Not very good , the stewardess were unfriendly and they don't like to be bothered. Cos was a night flight and they need to sleep.

Uncomfortable seats and flight attendant was rude as she insisted on waking up my husband to ask him if he wanted a drink. When he said that he was sleeping, she replied “without an attitude “. He was seated at 8c

The experience was good just the upcharge of over a hundred dollars was not cool.

No internet, not even westjet connect makes for a boring flight

Our first flight from LAX to Winnipeg was changed but you never informed us at all. It went from a nonstop flight to a stay at Calgary. This impacted our trip negatively as we arrived much later than we planned to. Our returning flight was horrible. The flight was delayed 6 hours!! And we were NOT going to wait that long. The only way we got on our original flight was running there. However all of our suitcases were now coming on the delayed flight. It was the worst experience we ever had flying. I want my money back.

Typical Canadian airline experience. Charger and tray were broken, food was poor quality, and yet you're still paying more than flights with equal to better service than elsewhere globally.

Good, a bit cramped in the seat as my neighbour was a bit large

There was a man who was very rude at boarding. On the other hand personal bag measuring box is too small compared to USA airlines,

While I appreciated the food (it was unexpected), it was interruptive for sleeping. We paid extra for reserved seats, but when we checked in they gave us different seats. I had to call WestJet arounf 11:30pm the night before our flight to get this fixed. We were give seats in the emengency row to resolve the issue.

Not enough food option. And not enough advices or information about what we are gonna eat.

Please make more option. And be more precise on the type of food you giving. Diner and breakfast can be different

I like how spacious the plane was but I did not like the fact that there was no entertainment

1 hour late No hot drinks No restroom in the back of the plane

I did the posting for 45 years. I just retired. I’m the only seat in the plane but didn’t have any phone. It has to be mine so imagine seeing 13 hours on the flat seat with a belt that didn’t close all the rest was OK.

I had wonderful wheelchair assistance through the Montreal airport onto the flight. Air Canada was excellent in this both at the Fredericton airport and the Montreal one where an attendant helped us through customs as well as transport and baggage security.

Flight was cancelled last minute due to Air Canada strike leaving us stranded and having to stressfully find a way home that cost hundreds of dollars in excess cost added to the trip. Having just experienced our mother's funeral service, this was not a good way to end our trip.

They went on strike before time and screwed us big time. Which is not fair. We respect their planned strike but why they went on strike ahead of time ??? Poor garbage management

Premium Economy is best if you can't get upgraded to Business.. Not as good to sleep for red-eye flights, but does the job. More space for your legs and arms.. The food is also better and the service is almost like business.

Awful. As we were boarding we were told the flight was cancelled. Then had to stand in a queue for 3 hours to talk to someone at the kiosk of Air Canada. They were not helpful at all. No empathy. My issue is not with them striking but the total disregard for the chaos and distress late notice caused. No thought on the impact this has caused.

Horrible, experience, 5 hours delay, they changed gates 3 times, the last one we had to wait for 1::30 hre for the door to open to get to that gate. 0 apologies from Air Canada, they don’t care at all about their passengers

I had a very disappointing experience with customer service. I was suffering from a severe viral infection that included a rash and persistent cough, leaving me unable to even sit upright. Given the circumstances, I requested travel credits from Canada Air, explaining the potential health risk to others onboard. However, the airline showed no concern for my condition and stated they were not in a position to make decisions based on health considerations. Despite my illness, I received no support or flexibility. Ultimately, I chose to forgo my flight due to their lack of responsiveness. It’s unfortunate that airlines like this operate without prioritizing passenger health and safety.

On-time boarding, departure, and flight. Electronic notifications about bags for the whole of their own journey too - from when they got accepted into the system through to being loaded onto the plane and then finally being disgorged onto the right carousel. That was an excellent feature.
