Arm rests are too small and too close. No screens, movie selection was very limited and poor. Food is pretty much overpriced cheap convenience store food.

I didn't have any problems during my flight. My main issue is with airlines in general, they keep offering less and less every year, AirTransat is no different.

Crew was good, helpful. Flight ran on time.would have liked to take airtransat home to MTL. But the price back from San Jose Costa Rica was MUCH more expensive than the flight from MTL to San Jose c.r.

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

We are a senior couple (70+) and chose emergency exit seats so we would have 2 seats together and neither of us had to sit in a middle seat. My husband is type 1 diabetic on an insulin pump and I monitor his blood sugar levels. I am 5'9" and 250 lbs and found the seats extremely uncomfortable. Toward the end of the flight I developed diarrhea which lasted a full 24 hours.

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

I was very nice to arrive earlier than scheduled. Very much appreciated. No issues with flight. All was good.

The on-board crew were professional and friendly and made the trip feel like we were taken care of well. The gate for the flight departure changed three times...not great but not terrible. Considering it was the day of the New Jalisco Cartel mayhem, we can't really complain.

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

Onward flight was okay. return from Lisbon was poor as we missed our flight due to a long line at the passport control. Air Transat made no effort to accommodate us even though we were at the passport control 40 minutes prior to the departure.

Seating and zone. The minor I went with didn’t even seat close to me

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

Food has been disappointing in both legs of flight to india

Great staff great experience, made a 2 hour delay very bearable

Great staff, great experience, made a 2 hour delay very bearable

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

I was my pleasure to fly virgin on my birthday for my first solo trip ever 🫶🏼

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.

Overall, flight was excellent but check in was very slow for Premium Economy. Economy queue was shorter but we weren't allowed to use it.

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

Air traffic delay meant boarding started, then plane was evacuated and passengers sent back to the terminal for 1 hour. Very little information shared.

Our AC flight was canceled not once but twice on the same day to Quebec City at Toronto Pearson Airport. 2;30 AC and 9;40PM AC flight. After having our 2:35 flight canceled, we were bumped the second time because of large student groups visiting Quebec City. We were sent to Montreal on an 11:30 flight which landed close to 12:45AM. We were given a hotel room at the Marriot Hotel next to the airport. We had less than 4 hours sleep before we being taken to the airport for our 7AM flight to Quebec City. We didn't have much time to use our vouchers given for breakfast once we had cleared customs for the 2nd time since leaving Toronto Pearson Airport. We missed a full evening in Quebec City and lost our hotel room for the night. We were exhausted the next day and missed an excursion we had planned. My wife and I are both seniors in our seventies, and we weren't happy to be treated in this manner. Air Canada could have used a larger plane to accommodate us and the other ten or so people that were bumped from their flight to Quebec City in order to accommodate student groups. We will endeavor never to fly Air Canada again in future and we will not recommend flying with this airline to our friends and families.

Better to not serve food if those are the options

It was a good experience flying Air Canada for the first time

They did not let us board because one member needed a transit visa, which was not evident at the time of ticket purchase.

I was charge a baggage checking fee $68!! I volunteered to check my duffle bag which usually goes under my seat!

Boarding - 3 of 4 flights were delayed and the gate staff did an ok job of managing the lines for boarding. Lots of standing around in line - more than typical. Crew - accommodating. If you are looking for warmth, you will not experience it with AC. But I appreciate their hard work and relative efficiency on 8+ hour flights. Comfort - My first 2 flights were cancelled the morning I was due to depart. AC rescheduled me on 2 new flights that created only minimal disruption and change to my itinerary (a longer layover, several hours difference in arrival time) and provided a 15 dollar food voucher for the layover restaurant which was the equivalent of a measly sandwich. My seats were changed which is a huge issue for my physical size as I require additional legroom for medical reasons, and I was put in a very uncomfortable seat without the option for seat selection. The bathrooms were incredibly dirty and foul smelling to the point of being nauseating and I was next to it during my longest of 4 flights. Entertainment - I always travel with downloaded entertainment on my own devices and a power bank, and am glad I did! The entertainment was completely non functioning for my 8+ hour flight home. We were provided a 15% or 50 dollar voucher on a future flight by way of compensation. Food - always just poor to mid. I also travel with my own food when possible as in flight meals and snacks taste strongly of packaging. Overall, this was a poor to mid experience, and I am resigned to the fact that airlines are never going to improve.

I did not like anything because the flight was cancelled yesterday and I did not get to arrive on time in Toronto as I was rebooked with another airline. This caused me to be really stressed out as I am an individual with back injury and to be forced to stay longer in an airport to accommodate a change of airline and the transfers associated with it Due to this I am probably not going to book through your website to eliminate this potentially chaos in the future

shittiest airline in the hemisphere. To improve - start thinking you're flying people, not cattle

Easy boarding, inflight refreshments came on time and comfortable seat

In my first flight with Air Canada we sat in the plane for 4:00pm to 6:30pm. Finally we were asked to get off the plane and we were told the flight was cancelled after 7:00pm There was o clear explanation of what was the problem. I was booked without my permission on a Delta Flight at 7:30pm that was leaving at 8:00pm and I still had to go get my luggage(my final destination was Rome with one stop in Toronto. The luggage claim for Canada was closed so had to return to finally get it on the luggage belt.. Of course I missed the Delta flight and all the next day flights were booked. I also lost what I paid for my stay in Rome because I did nt cancel in time. A complete nightmare.

The flight was delayed 7 hours and we were given 10 euros vouchers. This is ridiculous. The crew was not nice at all, they just did their job with serving food and drinks. Did not even apologize for the delay!!!!

Flight map did not work. Crew was great, food was good, plane took off on time and landed early. That's all I can ask.

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.

Business Class was very comfortable and the food and service was top notch.

Efficiency of staff, and comfort and cleanliness of aircraft was all great. Maybe a hot drink without payment at that time in the morning would be good!

The crew was very nice. The equipment on the 747 felt old.

As expected. Would have appreciated a 3-day headsup reminder as a reassurance that all is well.

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

Seating space is appalling. Seats and all surrounding area in "Economy" is built for individuals shorter than 4' 10" and below 120 lbs. Ridiculous. While I'm not expecting fine dining, the food was the worst airplane food that I can recall.

Business class lounge for my gate was closed and no email was sent, causing me to walk back and forth to different gates, etc for over 20 minutes one way. Flight entertainment was mediocre with very poor choices especially for business class cabin. Original flight was cancelled and rebooking was difficult and no reason given for cancellation.

Waiting area not big enough for all the passengers, no airport lounge.

Very comfortable flight and simple and directed one way and back. Amazing price.

We loved our flight attendant, Emma from Scotland, the meal and entertainment offerings were wonderful, the flight was smooth, and enough leg room to stretch. We would fly with you again!

Los Angeles to London. 25th of April 2026. Business class. I was flying backwards with a complete stranger snoring next to me. In Business class. Males and females, strangers lying next to each other. Seats were backwards. I paid for comfort. I got dizziness and stress.

I liked that we got there safely. I disliked long delays, gate and ticket agents incompetence and apathy and having my luggage lost. Five days later I've yet to get anything more than a generic apology from British Air. Luggage yet to be located, much less returned.

Long line with check in at the DIA British Airway counter.

The flights were on time. Cabin crew were nice. The food was terrible! Checking in was not easy using my phone.

Crew were fantastic and the aircraft was extremely comfortable, but outdated. Headphone jacks were worn out and sound normally only came out of one ear unless positioned just right.
