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.

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.

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.

The entertainment system was down; food by purchase only; several people did not receive their luggage. No one answers at the local office or online about the luggage.

Starlink is great Crew was polite Business class didn’t get a welcome drink just water and snacks were ok

very average service no complimentary alcoholics drinks unlike other airlines such as Porter airlines No decent seats available during check-in time the day before

Good but airlines getting smaller. I didn't like the meal but the service was fine. Flight was fine and luggage arrived. So good.

They were fast and I like how they used to entertainment system to play video about the safety.

Flight delayed. Connecting to night flight was stressful but made it. Jusr in time. Ran.88Flight was fine.

Hopped on time for the flight only to get deplaned and delayed another 2.5 hours.

Given I (and I’m assuming most people) have both carry in and a personal item included in their fare, I find it very unfair that on neither of my flights I was able to use the overhead for my small backpack because they were completely rammed with luggage, people personal items, jackets, hats and other items. So the only item I brought in had to be stuffed under my seat while they had their leg room and sat comfortable with all of their items in the overhead. This has to stop because I was uncomfortable on both flights when I only had one smaller item that could not be checked due to its contents (medication etc). Plenty of people could have checked theirs but chose not to and then took up the space allotment for 2 people.

Flight attendants had a little attitude. Food tastes no good.

From pre boarding to flight attendant, crew and baggage handler, excellent. Didn’t lost my luggage like West jet.

Very poor. The flight was delayed from Toronto because some forget to do there job . I got to my connecting gate in San Francisco 10 minutes before the departure.but this didn’t let me board even though the flight was still there for an other 30 minutes. The the gentleman at the unite airline desk told me that they usually wait for passengers but air Canada called and told them not to we I been rerouted to Manila instead of Hong Kong . In San Francisco they mad me check in my carryon bag . I was told the it will directly go yo ho chi minn cuyt but I was told that by the Vietnams airline desk that’s not there I’m 10 hours behind my scheduled flight and looks like I I’m going without baggage. I don’t have a chance of catching ..

I didn’t have any food but my Prosecco hit the spot. We left on time and the crew was friendly.

The pricing was split into an ultra basic fare with a comfort seat upgrade. This is misleading. Never were we shown an ultra basic fare. What this did because the fare category was ultra basic we could not bid on an upgrade first class seat. All e mails from WestJet were for ultra basic category with my wife and I upset as we could not confirm this with anyone from your firm.The check in counter were not going to allow our carry on but after some checking saw we had ultra basic and a comfort seat upgrade. They could not figure out how this was done. Now we have to go through this again at the gate in Mexico. Unless I missed it - please let customers know the billing in future. Respectfully. Gary & Nancy Moughtin

Flight didn’t happen because both my connections were lost and Toronto wouldn’t let me board. I was checked in to all 3 flights at the check-in fest in Dublin.

The flight didn’t happen because they apparently lost my check in and wouldn’t let me board.

Access to movies was rather confusing. Apart from that, I have no complaints.

I wasn’t able to book or pay for a seat and they forgot to check me in for my third flight so I spent 24 hours in Toronto waiting for another one.

I wasn’t checked in for the third leg of my flight, my bag was checked through to Dublin but when I went to the gate in Toronto they said I wasn’t on the flight and had given my seat away. I had to wait 24 hours for another flight and instead on the one I had booked it was now 2 flights.

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

The agents at the Kelowna YLW airport were really grumpy. Same with oversized baggage person. Staff on the plane were great.

Flight was early. That’s the only positive I can share. I paid for wifi on the flight and it didn’t allow me to use any streaming services so it was a waste of $20. West Jet also lost my ski equipment on my way to a ski vacation. They told me it would be delivered to the hotel as soon as it arrived at the airport. It was never delivered. I had to pick it up at the airport on my way home. I am completely disgusted with my experience on west jet

American Airlines is a miserable experience. It is predictably miserable, in the sense that every time I fly American, I brace myself for the certainty that it will be unpleasant and uncomfortable. But it is unpredictable in the sense that I never know if the flight will be on time or delayed nine hours (both happened to me this week). I never know if I will be able to sit in the seat that I selected when I purchased the ticket or if I will be told by Customer Service (!!!) that I must relocate from first class to a seat in the back of the aircraft with no explanation (both happened to me this week). Will the food be frozen and half defrosted, or scalding hot? Will the drinks be warm? Will the flight attendants be surly and mean? Will the toilets be cramped and foul? Will the seats be narrow and uncomfortable? Will there be a real electric outlet at the seat, or just an unreliable USB-2 port? Will there be enough seats in the boarding lounge or just a few? Will the boarding process be smooth and efficient, or will the gate agents mess it up and delay it needlessly for 30 or 40 minutes? Will the catering and cleaning crew be prompt or will they take an extra 30 minutes? Will the brakes on the aircraft work properly, or will the pilot delay takeoff for four hours while the ground crew attends to what can only be described as routine maintenance that should have been done the night before? I've eexperienced every one of these unpleasant things this year, 2026. The only thing I can reliably count on is that American will find a new way to make the experience of flying as miserable as they possibly can.

I was in last row so that is never great bc the person in front of me leaned his seat all the way back into me.

I booked 1st class, my flights were changed and I was sitting in the middle at the back of the plane. A far cry from the 1st class I purchased for my flights. I am grateful I arrived on time.

Meals were not so good. Snack between the meals was very bad. Like Japan Airlines, they could eliminate the snack and make the second meal much better.

The gates should be ready when we land. Waiting on the runway for a hour is ridiculous.

Baggage allowances are terrible and the experience of only being allowed one bag and paying so much to take sporting equipment to a known ski area should be addressed.

Flight was smooth, quick and felt safe. The 2 delays not happening would have been better but I guess that happens in the airline industry

The boarding was as always, the crew tried their best but not enough. The food was a disaster I had dietary restrictions that were half met because the company did not loaded the food for the flight. The entertainment screen was fine but content was not and also they removed the free messaging option from the flight and they charged 30 dollars for that crappy bandwidth. This flight is not worth the cost and the company is going down on quality.

I like how the crew and pilot kept us updated Even though our flight was slightly delayed. We made up time for it in the air. I really did enjoy my seat and amenities and my trip and value overall.

This was the best 2 flights I have had with American out of SGF. Great crew both flights.

This was my second leg of my trip and was delayed so was worried about my connection in Montreal. Still hungry so on boarding I asked a flight attendant if I could use my $14.00 voucher on the plane for food as I was starving. She said she would check and let me know but she never came back. So no food again as none was offered. Had to get my bags and check them again and that was ok but don’t understand why I had to go through security and because of them almost missed my flight. No food offered nor possibility to purchase food so still hungry and just watched a movie and hoped I could get food when I landed. Was able to use the $14.00 voucher to buy something and had my family bring food as I was now starving. I’ve been travelling on AC for years and this was my worst experience ever. After our flight got cancelled in SXM and was told the staff there didn’t work for AC so couldn’t do much to help us was not a good experience

Staff looked unprofessional. Sloppy uniforms and hardly a smile to be found

After 3 hours of delays, they ended up cancelling my flight. And although I could purchase one-way tickets to get to my destination, they would not offer me these flights as compensation for the cancelled flight, and I didn't end up making it home until 13 hours after I was originally supposed to arrive. It made for an extremely strenuous end to an otherwise good trip.

Be careful about the bad policy and when purchasing seats

Very disappointed with premier lounge. Food selection very poor, both coffee machines out of order. For the price you charge for an upgrade, the seats don’t fully recline, movie selection is old. Not very good value. Asian airlines are light years ahead at a more affordable price.

Flight late with no explanation why so late boarding. More than made up the time in flight. Woman in seat behind me would not allow me to recline my seat so could not sleep. Slow to clean up after meal so has to leave my tray down. Flight attendants average at best. Premium economy experience was poor. It was a special trip for us, a 70th birthday. We could only book seats that were apart and no efforts could be made to get us together. Just poor all around

Business Class was great with two exceptions: they should board Business Class Only first, then loyalty, then handicapped and families with young children then by zone. With all the loyalty and credit card holders and families with kids, dozens boarded before us and we were in row 3. My only other compliant with Air Canada is they don’t serve drinks and snacks in business class until at a cruising altitude. Transat and Emirates serve prior to takeoff which is especially nice during boarding of big planes and de-icing.

The only good part was what we paid for, we travelled premium economy, good comfort travelling with a baby. Flight with AirCanada was again delayed for more than 4 hours, service level is horrible and they don't care. They deliver the bare minimum for a world class price. If you can avoid canadian air lines, do so, oligopoly does not help them to strive for any service level.

We left over 2 hours late and they didn't even give us a complimentary snack, when getting to the desk I asked if I could be put in a row with only 1 other person or an empt y one I was told the flight was full when the last two rows were empty. All around over it

Again, we were rerouted all the way to Zurich and had a longer journey than expected.
