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.

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

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

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.

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.

Flight delayed any hour and couple of big gate changes

Great flight and crew. Food isn't free and neither are headphones...

Super unproffesional flight . Flight attendants were unproffesional. I could hear them gossiping about theor boyfriends the whole trip

The connecting flight lay over was 4.00 hours, the gate agent booked me on the next flight which was about to depart at no extra cost.

We were lucky enough to arrive at the right time. The staff at YYZ did our complete check in and luggage tags for us. Even made sure we knew where we were to head next and how to get there. It truly was one of the best and easiest check inside. Thanks team.

I was advertised a free seat selection for a "Smart" fare through BusinessClass.com. I was never able to select a seat. I thus paid extra for a bill of goods I was never provided. would love to speak with a representative of Kayak

Overall good. We weren't able to find out about food options for the flight and there was nothing I could eat due to allergies. The biggest problem was getting our checked bag at Logan. Waited an hour!

I loved both of my flights to Ireland and back to Boston. The only negative was it took over an hour for the baggage to be delivered.

The boarding time for this flight was ridiculous, longest in all my time flying. There was a problem with the original plane so it was switched at the last minute. Not a good substitution. We were delayed in departing. The bathrooms for economy were not adequate. The crew were pleasant but not present in the economy section, in an ~ 8hr flight only twice did they come through offering water, easy to get very dehydrated. I had to go and ask every hour for more water. The seats were cramped, and I have no idea what they did to the coffee but it was undrinkable. The food, was disgusting, utterly inedible, I am stunned by the lack of care and quality with the inflight service, very disappointing, I had expected better from Aer Lingus.

Excellent cabin crew. They helped a number of passengers with mobility challenges and a mother with a 3 year old and an infant. Better than most other airlines by far. Well done Eduardo!

Good, I slept the entire flight so I cannot add many inflight details

Internet didn’t work more than 30 seconds at a time. Stared at my seat for most of the flight.

We had a connection flight in Toronto and the checked bags didn’t arrive to the baggage claim area 1.5 hours later- this caused us to miss our flight because of the delay. I called Aer Lingus to see if they could help, but since I booked it through a third party on Kayak, they said they couldn’t help. Are you able to help with this? We needed up getting a hotel and renting a car for the solution.

I didn't know if the plane was even go And the plane shook like it was from the same era as Indiana Jones

We traveled with my 90 year old mother and she was well cared for by everyone from the wheelchair attendant to crew. Greatly appreciated!

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

As someone who never flies WestJet unless there is no other viable option I have to give this crew credit where credit is due. Extremely well done everyone.

Great seats, super comfortable, but no in flight entertainment which was a let down

Single flights to Cancun purchased through third-party, initially had issues printing luggage labels with the lady at the airport Pearson… Was super friendly and assisted quickly despite being very busy

Require more comfortable seats. More frequent water/beverage service. I would like better food choices. Overall, very mediocre. I now only fly WestJet when there are no other schedule options - no longer my first choice.

we were upgraded to business class, not sure why, so the flight exceeded our expectations. Perhaps this was because the flight Cancun to Calgary was a nightmare , not even guaranteed a seat upon checkin at the airport.

Not the fault of WestJet but we had to wait in the plane on the tarmac in Cancun for 1 hour.

The 787 was amazing. Listening to screaming and crying children for four hours was horrible. Small children should be in one section. Seats were very comfortable and leg room was fantastic. Information was very generic on timing.

A lot of people needing bathroom before arrival some didn’t get to use; plane a little small felt cramped but worked still a bigger plane would be nice. Crew was friendly and flight was on time and smooth. No food for vegans 🤔

lucky i am considered slender. but i am 5'7", so in case of emergency it would have been completely impossible to put my head on my lap. THERE SIMPLY WAS NO ROOM TO BEND OVER, ALTHOUGH I AM MORE THAN CAPABLE(AS A LIFETIME OF YOGA WILL ATTEST TO). CRAZY DANGEROUS HOW SQUEEZED INTO THE SEATS WE WERE. i have travelled to mexico for almost 20 years, mostly on westjet, but they have obviously squeezed more seats into the 737 to ,,,,,you guessed it make more money!!!!!! also i had to repeatedly move my 'seatmate' as she kept falling asleep, and as she was definately not slender, she squished me into the window seat all through the flight., if i could have jumped out of the plane and swam to mexico i would have done it in a heartbeat. TERRIBLE FLIGHT, NO FOOD, OH, SORRY, FREE PRETZELS OR COOKIES. LOTS OF BOOZE FOR SALE THOUGH!!!! WORST FLIGHT OF MY LIFE!!!!!

Broke my luggage and I can't get a resolution yet.

There were no TV screens - even in Business class. 5 delays, and only given $12 meal voucher! Terrible!

Flight was delayed again and again ultimately almost three hours getting us to our location at close to midnight by the time we got in and out of airport to destination. I had taken time off work to enjoy an evening at destination and that was now wasted

No food/snack served during the flight. Crew wasn’t interested at all. Flew American First but flying low cost with Ryanair is even better

The flight was good. The only reason I did not say “excellent” was the delay

They could have done a better job announcing the boarding groups and asked for more drinks (water) if needed.

Ac was broken so we deplaned, waited 2 hours, taxiing for takeoff they said the plane would not fly so we went back to the gate and got a new plane which took another hour. In all a 4 hour delay for an 80 min flight.

We were delayed bc ground crew gave the flight crew the wrong paperwork. We taxiied to the runway then back to the gate to get the correct paperwork that no one bothered reviewing the first time we pushed back. Boarding was rude and stressful like it always is. Gate agents and flight attendants are all over 55 years of age, embittered by years of underpayment From AA leading to their passive agressive bitchiness for no reason.

Boarding time was easy & quick. Crew was excellent. In-flight entertainment was great/easy. Seats are too small and not enough room between rows: felt like a sardine/very cramped.

Ground crew forced me to double pay for infant international charges, when I complained about this and told them, with proof, I already paid they threaten to not allow me on the plane because I was “being rude”. Horrible ground management, horrible airline.

We loved our flight attendant (Emma, from Scotland), the meals were perfectly spaced out, and the in-flight entertainment was super generous and delightful.

Why don't they board from the back of the plane to the front. We have to move by all the people and their luggage to get to the seats.

The boarding call announcements versus the Staff announcements versus the digital signage board on the out-going and returning flights WERE NOT IN SYNC. I was sent through check and re-checks 3 times. WHY?

With three empty seats across the aisle from me I politely asked the crew if I could sit in one of those seats. They initially told me I couldn't do it for my safety. When I pressed them again they blamed the captain. So which was it? I didn't appreciate either nonsense explanation simply because they didn't want to honor my request.

I couldn't get a vegan meal because I booked via kayak but everything else was lovely

Great room between the seats, food was excellent, very comfortable overall and could have stayed on the plane even longer

BAD!!! due to delay I missed my connection in MEX, had to pay for hotel and new flight for next morning increasing my spent for $1,000 usd

Aircraft delayed for two hours due to a technical issue with the rear emergency exit door slide not working.

Superb staff, ingenious seating in Club class. Superb food and service. Loading and unloading. Ample cabin overhead luggage space. But the earphone socket was damaged and did not give binaural audio. Very hard to follow a film over the engine noise. Nor could I get to play Sudoku for want of instructions.

The plane seemd untidy and old. Ran out of food and drinks
