The flight was terrible based off the temperature in the plane and the air smelled so stale and gross. I have never wanted to hosed lore in my life after I got off. The food was disgusting and seemingly low quality. The staff was friendly. The bathrooms were so gross after a couple of hours. I will definitely never book with them again.

The flight was terrible based off the temperature in the plane and the air smelled so stale and gross. I have never wanted to hosed lore in my life after I got off. The food was disgusting and seemingly low quality. The staff was friendly. The bathrooms were so gross after a couple of hours. I will definitely never book with them again.

The crew was great. There was no entertainment and the internet wasn't working. We sat in the run way for a LONG time which is always so upsetting. The seats are very close together and the flights are completely full which makes for a tough flight. Flying is just an uncomfortable experience.

Very kind crew. Vegetarian food better than usual. Prompt take off. Entertainment worked well. Could always do with more room!

I liked the reliability. I liked less the chair comfort...

The dinner was bland and boring, but the economy seats were surprisingly comfortable. The flight was very packed.

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.

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.

We were treated well by the staff at the airport and on board aircraft. Delay was uncontrollable due to the weather. Had to wait for another gate as we were late landing in Fort Lauderdale.

I was supose to have a carrey on incluided for each passenger and they made me paid 75$ each at the gate.

Great crew and entertaining Captain. Seats were not what we had expected based on my booking but things worked out in the end. Of course, like all airlines these days not enough leg or elbow room.

Terrible. I was charged $75 for a checked bag when I only had a carry on. The lady at the desk said she couldn’t refund me the money and that I had to call westjet. I called the next day and they said they couldn’t refund me because there is no way to prove I didn’t have a checked bag.

I'm so frustrated my flight was canceled they give flight on August 5 which is not sure. Its was big mistake I booked my ticket from kayak.

Switching flights in Halifax was a nightmare. There was no agent waiting us when we disembarked to provide my mom with gate to gate assistance as we arranged. Our flight was delayed so our window to catch the other flight was very tight. The airport was poorly marked as to where to go. The plane was fairly crowded and space available was cramped.

Flight was delayed for 5hours. Food vouchers just aren’t good enough

It was disappointing to see the huge number of people who were allowed to board who were claiming to either be disabled or needed extra time to board who practically ran to the gate as soon as boarding opened. One of the female flight attendants in the premium economy section refused to let a lady with an infant use the toilet next to row 9 to change her baby even though the path back to the rear toilets was blocked by staff and trolleys and said she would have to carry the baby to the toilet during the descent phase when turbulence was present. The passenger refused and the baby had to wait until landing. It would have been no problem to allow this infringement of weathers petty rules. The flight was also very cold due to a cold draft throughout the flight from the bulkhead ceiling which was not controllable.

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.

In spite of purchasing premium, I felt it was perhaps the most uncomfortable seat I have flown in. The base was either broken or poorly made and had no support. Even placing pillows and blankets on the seat (1D aisle) didn’t help. It made for a long and mostly sleepless six hour flight. Crew also were very loudly talking to each other through the night making it very hard to sleep. It was purchased for the price, so I get the risk, but was not impressed.

Business class lie down seats on WestJet aren't very comfortable. Crew were excellent and overall flight was ok.

There was a medical emergency that the crew handled very well. There was no “entertainment” of any sort-no movie/music/whatever. Food was typical of airlines: mediocre.

A group of a family sat behind me. I think up to 8 people? Constantly talking and making noises. Stewardess did nothing at all to make them stop. Told the Stewardess and they said they'll handle it but they didn't 🙄. Food sucked too.

Noticed a marked difference in keg room from last flight. Would consider other airline on next red eye.

Excellent flight crew. Very comfortable plane. Entertainment options on air Canada were great!

I cannot think how they could put more seats together but they did. So elbow to elbow leg to leg for these long journeys they should consider leg space at least. Since they did not offer to check people's carry one space was tight and if you did not get on first people used your assigned overhead storage so now your doing these same to another. Cascading inconvenience.

It was great to have a vegetarian meal option, but departure was delayed because they had oversold the flight. Air Canada, you’re in charge of how many tickets are sold: don’t oversell!

I liked the quiet airport and no queue. I don't like that when booking it is not clear that there is teared economy, that you have to pay extra for choosing a seat and for your luggage both ways. We didn't find this out until checking in. It turned out not very economical.

In flight entertainment system did not work across the whole plane for entire flight. Seats were very cramped. Cabin temperature was freezing cold. Crew was miserable and answered everyone in a short and barking manner. I’ve flown air Canada many many times and never had an issue. But this was unpleasant.

They screwed up so bad, I asked for a short check for my luggage since we had a 21 hour overnight layover in London at a hotel. They said I have to receive my luggage in London because it’s an overnight layover. Get to London, nope, my bags aren’t coming off they are staying in terminal 5 over night and going straight to Ibiza. So we had no luggage for a whole day and basically stuck with no clothes or washroom stuff. Finally get to Ibiza and my luggage is completely smashed and damaged and missing a wheel. Now I have to drag this 50 lbs luggage around Ibiza islands for 10 days. Wtf. So pissed off Air Canada is LITERALLY THE WORST AIRLINE IN THE WORLD

Great flight ✈️ I requested a vegan meal and don’t think offering frozen fruit cup for breakfast is a good idea people want something warm or neutral like the muffin but it was cold from being in the paper bag with the frozen fruit 🧐 and unfortunately I didn’t have either and I don’t like wasting food so that was a disappointment. Flight was on time departure and arrival flight crew were good.

From my experience, I see there is room for a greater mixture of cultures, for example, a mix of the nationality of cabin crews, food, music, food, etc.

on time quick service but food so so and seats very small. no leg room. I think passengers should not be bringing so large carry on suitcases and should have free check in. Then boarding and unloading would be faster

Flights were delayed and due to a checked hand luggage bag by an overzealous gate agent in Berlin I missed my ground connection costing me another £80. Food was cold and bland, I honestly expect better from a national carrier operating out of one of their major hubs.

A bit more space? Not practical, I know. I felt squished in but part of that could have been the man sitting next to me.

It was my first experience in business class. It was everything I expected and more. Service was impeccable, food was delicious and I felt rested once I arrived to London

Missed our flight to London and we were put on coach seats to Munich.

Seats were terribly uncomfortable! Couldn’t sleep! I paid for good seats when scheduled with Lufthansa, got crappy mid-section seats on Air Canada!

The seats are much too narrow and the arm rests are hard and awkwardly high, resulting in shoulder cramps. I am an average sized person ( definitely not overweight). The seats are a similar size to car seats with the added discomfort of incorporating hard plastic arm rests, that force average height individuals (I'm 5 ft 7 (f)) to hold their arms uncomfortably for several hours. The seats are much too close to the ones in front and behind making it extremely difficult to allow fellow passengers to get out, especially when the seat in front is declined. The leg room also necessitates knees banging into passengers backs for the entire flight. This used to be a quality airline who now offer mediocre service for premium cost, coupled with charging exorbitant prices for basic needs, like a seat, or luggage. Blatant and unabashed gouging of clients.

Try to humanize onboarding and take AI out. It's embarrassing and useless

I ended up buying (for $340) "extra space" seats because I my flying partner was given a STY boarding pass, leading me to conclude that she was on standby and that we had to buy seats on the flight. I later learned that the flight was not sold out and that we could have gotten on as usual. To be honest, I felt swindled.

I'm Canadian. I have the unfortunate experience of pretty not having the choice to fly with them. THEY ARE TERRIBLE.

Bread stale. Croissant stale. Person behind me was kicking me throughout flight. Boarding slow.

All good, professional service, and arrived close to on time.

This was a special trip so we booked first class. It was obviously an old plane as the seats weren't that comfortable or spacious. We were delayed 45mins taking off as the "little engine that starts the big engines doesn't work". The powered divider between myself and the next seat in first class didn't work and my electrically powdered seat didn't work so I had to move seats to try and get some sleep. Food and drink were good, crew were great. But I'll never fly with BA again.

Need thicker and wider blankets. Food was below standard especially in the fist leg.

Decrepit planes, poor business class layout designed to maximize revenue, no decent movie selection.

Boarding was efficient. Flight left on time. Wasn’t full so we could spread out a bit. Food was ok.

The A350 is a great plane but BA's seating was incredibly tight (eg compared to the same plane as flown by BA's partner Finnair) and with a middle seat it was very claustrophobic

Staff and crew where very nice and friendly. Just need to improve the timming om the meal and beverages.

Lost bag - again. No help from staff at Nice - they have a handling agent who does nothing No emergency kit Try calling BA - they eventually found the bag - now on later flight. Trying to get someone to help in the short term is impossible. If I am unhappy - then I have to log it on a website. The agent said he was only able to help with future bookings - not assist in the chaos BA had caused. IF YOU WANT SERVICE WHEN THINGS GO WRONG - PICK ANYONE BUT BA. Personally - I'm joining ABBA (Anyone But BA) again.

I asked for assistance for my mobility issues. It took over 45 min to find someone to take me to the security. then I was deposited at the lounge and I was supposed to be picked up. No one came. I almost missed the flight. There was no offer of extra water, snacks or anything on the flight. Food was OK given that I am gluten and diary free. Seats were uncomfortable and very little stow away space.

The seat was a bit crowded since the person in front was reclined. It’s my personal belief that if the seats are allowed to recline, there should be more room. The service provided by the crew was the best I have experienced.
