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.

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.

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.

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

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.

Despite exit row seating, which gave leg room, seating was so narrow, the next passenger spilled over onto my seat. WiFi did not work.

It was okay. The seating didn’t give you much space especially when you book a premium. It was still pretty close. The seats had no screens which was a disappointment. The crew was awesome though. Again I wish the wait between families with children boarding and general boarding was a little longer to give families some time to get situated especially those bringing a stroller like myself or for solo parents travelling like myself who has to do everything. The time between boarding zones especially with chilling is so short, I had to gate check my stroller and did not have enough time to pull it down and transport my luggage inside all while having my infant strapped to me or to even ask a flight attendant to assist as they’re busy with the the general boarding going on

Flight itself was not bad at all. However: my checked bag (checked in Calgary) did not make it onto this flight as I found out after I landed at EWR. I still don't have it but it appears that it is on its way to me.

The crew was amazing! I was a bit surprised and disappointed that there was not wifi available for personal use. The only thing I would change would be the seat cushions. They are not comfortable at all for long flights.

Flight and attendance were very good we had 2 hour delay that took the shine of it

Rude flight attendants with poor service. Worst first class experience I’ve ever had.

The plane was very cramped to point there was no way not to touch person beside you and a stewardess screamed at my son when I touched her arm to get her attention to let her know she forgot to give him his dinner when she passed him and gave a dinner to passenger behind him. Very inappropriate response and She never came back to apologize and other stewardess said she was sorry “if I felt” she was inappropriate. Horrible experience and she should be reprimanded for her behavior

The seat design in the premium economy section leaves virtually no room under the seat to store a bag or purse. Other than that, it was a great flight. Arrived early.

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….
