My screen was broken so now movies, etc, but I didn’t really mind. They did work on it, so good effort on their part.

i was not able to take my flight because the information i needed to book my dog correctly was not provided

They never sent me a confirmation to say my flight time had changed so I cut my holiday short by 6 hours Had to pay over 50 American for my luggage to be checked on the way home and that’s more that it cost on the way there. Arbitrarily charging more for the same thing when the passenger has no options is shady The cabin was an icebox going there and back, if all the passengers have their gloves on and their hoods up that should be an obvious sign to turn up the heat

The Turkish was good . I had a problem with air Transat terrible experience for me

Very good. A lot better experience then I expected for an economy flight.

Porter airlines was good. I didn't have the best experience when booking through airfare assist however, as I got no final confirmation from them that the flight was booked until I called them. Even then, the confirmation code they gave me was incorrect and couldn't be used for check in. On a positive note airfare assist was actually picked up the phone relatively quickly when calling

The flight crew were very good, polite, and professional. Unfortunately, the rest of the experience left much to be desired. The food was extremely bland—almost tasteless. We chose the non vegetarian .The lasagna was just plain pasta with a tiny garnish and no seasoning. It felt like eating starch only, The bigger issue was with luggage and space. We boarded with three tickets, and while the seats in front of us were nearly empty, all the overhead compartments had already been filled by passengers boarding to the back. This left us and many others with no overhead storage for our carry-ons. Our bags couldn’t fit well under the seats either, which meant we lost the little legroom we had. The result was a horrible, cramped experience—sore knees, no space to stretch, and no way to rest or sleep comfortably. According to the crew this was a rather normal thing. It is obviously normal that people board with handbag and carry on but they should be only allowed to use their overhead compartment and under their seat not the way it is managed that all the spaces in the front of the plane being occupied by the people sitting way back in the plane.

Everything was horrible. On the day of my departure, I was denied check-in and boarding because my reservation only showed one of my last names, while my passport contains both. This minor discrepancy could have been easily corrected, but I was informed that no adjustment could be made. As a result, I lost not only my outbound flight but also my return flight and had to purchase a new ticket at a significantly higher cost.

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.

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.

My recent Air France flight from Paris to Toronto was a genuinely pleasant long‑haul experience, marked by strong service and thoughtful touches throughout the journey. The boarding process was orderly and efficient, with only a short wait before passengers were invited to step onboard. Everything moved with calm coordination, setting a positive tone right from the start. Once in the air, the inflight crew truly shined. They were warm, friendly, and consistently attentive without ever feeling intrusive. Their professionalism and upbeat energy made the cabin feel welcoming and well cared for. The meals and overall service were very good—well‑timed, nicely presented, and satisfying. Air France’s reputation for quality inflight dining held up, and the crew ensured that drinks, snacks, and small requests were handled promptly. I traveled in a business‑class pod, which offered excellent privacy and comfort. The seat itself was spacious and well‑designed, ideal for both resting and working. The only minor drawback was that the pod felt a bit warm when fully closed, but it wasn’t enough to detract from the overall comfort. Overall, this Air France flight delivered a smooth, friendly, and enjoyable experience from gate to landing. The combination of efficient boarding, exceptional crew service, quality meals, and a comfortable seat made the long journey feel easy and well supported.

The flight crew was exceptionally friendly and helpful. Also the seats were comfortable and roomier than many other airlines.

I don’t like that an equipment change caused my seat to change from 23A to 44A. The boarding was also delayed. The crew were excellent, however and very attentive. The food was not bad.

Our flight crew were terrific. And they handle a difficult passenger with finesse.

I don't understand the concept of paying to get your personal luggage onboard and then asked to check it in.... either sell the space or don't, its a hassle to carry those all through the airport just to make a check in at the last minute.

My experience was good overall, the quality of the food really decreased! There used to be a choice between meat and fish now it’s between chicken and pasta! In the choices of entertainment meditation has been added which is very good. Soft chair workout to improve blood circulation and avoid phlebitis should be added.

They lost my baggage and I still have not got it back. Disgrace

Excellent apart from transport to actual plane 10 minutes from the actual gate , walking out in the tarmac in the rain and having to climb stairs to enter while holding luggage.

No bording was given for next trip on same carrier, food was very moderate.

A couple of minor delays in boarding but very professional and efficient staff.

Lounge was top notch h with great variety of food and drinks. Cabin crew were great. Smooth flight.

My seat 3G did not go down fully and the buttons were not working properly

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

These are one of the older seat arrangements facing away from the windows! Not particularly convenient sets. No storage spaces. NO COAT HANGING HOOKS. Inconvenient business class seat compared to any other airlines of similar class. Staff are excellent! Extremely professional, friendly. Food is good too.

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

Premium economy more comfortable than economy, but not by much. Did was awful, do not try the omelette. Flight crew were helpful. Flight was delayed by over an hour. Overall but bad, arrived safely and thank God.

Food was excellent. Service was very good. Staff was very helpful to all passengers.

Your flight delayed at Heathrow n I almost missed my mother funeral.you idiots. I had to waste 10 hours in different airports. Thank your stars I'm not suing you.

Seats were old and dirty, for a long haul flight you expect to be able to recline and for the av to work properly. Choice for vegans was fruit….

The Virgin Atlantic crew was very good. However, the equipment was OK, the seats were OK, but her bags did not arrive with me. Two bags showed up a day later and I’m still waiting for my third back.

I liked the fact that we arrived on time. What I did not like, I paid for a seat. Unfortunately a very large women sat beside me (required a belt extension). Her body spilled to my side. Not her fault but I had to lean to the left because her body was literally on my side of the seat. This caused a back ache. I was unable to sit straight the entire flight. There should be some form allowance (wider seat) for morbidly obese passengers. These seats are not designed for extremely obese people. I feel compassionate towards these obese passengers but I got off the plane with a substantial lower back ache. I myself have a degenerative disk disease and this did not help me

It was a short flight so, everything went smoothly and we got to where we needed to be safely.

Very tight seats - no legroom at all, very tight to the person in front of you. If you have basic fare, you are loading zone 6 regardless of where you are sitting in the plane - meaning even as a middle aisle person at the front of the plane, I had to get people to get up and let me in as they had boarded earlier. Having to pay for a carry on is criminal. I am a frequent flyer, and air Canada has now joined the list of other terrible North American Airlines.

Delayed by 5+ hours and they give a voucher for only $20 CAD which isn’t even redeemable at any place with edible food. Then took almost an hour to clean craft after it landed. And nonsensical boarding delayed even further. We didn’t leave until 1:30am….

I travelled in Business class for the first time and wish I could do that again.

the seats aren't the most comfy -- too little padding and I could feel whatever the passenger behind me was doing. Otherwise, it's all good.

This flight didn't happen for me because of overbooking.

Everything was simple and easy. The lady at the gate was super friendly, I wish I had her name to share. She's a little older, dark-haired. You can tell she likes her job and would be a great influence on any young people training with her.

During the pre-departure safety briefing, the flight attendants rushed through the mandatory safety announcements in both official languages, making it difficult for passengers to clearly understand the instructions. Given the importance of these messages for passenger safety, this lack of clarity was concerning. Perhaps use a recoded message to alleviate this concern. Additionally, the flight attendants appeared to lack the professional attentiveness typically expected during a flight. Rather than focusing on timely and courteous service, they seemed more engaged in personal conversations than in addressing the needs of passengers. I hope this feedback is taken constructively and helps in maintaining the high standards of professionalism and care that travelers expect from a national carrier: AC.

Service is pretty good. Sandwiches have to be purchased but I’ve bought my own food. Seat was comfortable and various movies to chose from.

The longer flight on our leg back to the US was fine. Boarding was great, we had to stay on the runway for a bit after boarding… they kept it cool uncomfortable.

Paid for exit row at the back of the plane. Window seat with lots of leg space. Food was inedible (as usual). Brought my own.

Missed flight. Requested assistance for my father and he did not receive it in Paris.

Poor food on flight between Toronto and Stockholm Airport Toronto too crowded

Business Class Configuration was excellent- private and comfortable. Crew and service were excellent. I really appreciate Air Canada cabin pressurization equal to an altitude of 8,000ft. Upon landing, I felt more alert and refreshed than typical for international flights

Hard to use tables and TV screens interfere with the enjoyment of flight experience. Other than that it was a smooth and comfortable ride and we were well taken care of.

The flight crew, the on-plane service, and the food were fine. The seats lacked cushioning and were uncomfortable compared to other planes from recent flights. The plane was initially delayed one hour and that expanded to 1.5 hours. When we boarded, there was insufficient room for our carry-on bags, which added more time to disembarking from the plane. It appeared the Air Canada staff or the Toronto Airport staff were less than competent to handle whatever the issue was that caused the delays, which was never communicated.

Boarding was haphazard after people with small children or walking difficulties

Tiny, cramped seats with minimum leg room and hard armrests. Basic needs like a seat and luggage came with an additional charge. Budget airline amenities with premium airlune cost. I won't use this airline again.

I paid a lot of money for seat selection and was miserable for flight duration
