Check in slow even though completed online check in, there was no bag drop available so had to query for 90mins as only 2 staff on desks.

Check in slow even though completed online check in, there was no bag drop available so had to query for 90mins as only 2 staff on desks.

Flying to a far away destination is a miracle in itself, so please take these with a grain of salt. The seats are a bit tired, and need a freshen up. The entertainment could be a bit newer, especially with all services available now. The food really is where we need help. But again, flying is a privilege, so all is good.

Not so much porter it's your site! Not good

They are a sister company with Air Transat and the two companies do not work well together. If you have any issues the two companies will blame each other and you will miss your flights. The help line does not help

Never book through a third party. Book through Air transats website. Terrible process to get help and many issues happen with them and sister companies because half the flights you book with them aren’t even through air transat.

The plane was pretty full, and we dis not have any includes meal for our 4h30 flight? And on-board entertainment wasn't available, there was no TV or plugging to charger your device on the plane. They told us to download an app if we wanted to watch movies but it never connected, that was a disappointment, the r we st was very good though and the crew were really nice!

Seats were very tight especially for first leg of trip.

Not necessarily a Transat issue but it took 2 hours to go through immigration. Tried to reach out to Transat for resolution but was unable to reach an agent.

The flight was excellent, once it started, however we were delayed two hours when the first plane’s engines wouldn’t start. They found another identical plane and transferred us and our luggage in under two hours and made up almost an hour in the air.

Really low cost trip for the huge amount I paid…o paid 550 dollars just for the trip, one way trip, plus 95 for 1 luggage’s and the second 135 dollars…no blanket, not headphones for entertainment, food was served after 3 hours and 2 hours after, breakfast was served Bad, low cost company for high prices

Liked getting into Milan at 10 AM. Also ok to get into LAX at 9:35 pm. - less traffic driving home. Layover a bit long - say 3-4 hours each way. Montreal airport kind of grim these days. Would lose the duty free area. Think art versus advertising. Maybe local shops and food spots. And keep layover short - like 1 hour on Finnair in Helsinki.

Upgraded to sit at the exit door so good leg room.

I had a good experience. I liked being informed about the status of my luggage

Orderly boarding. The flight to Montreal was difficult to get to on time, but had help from staffer.

The food on this 5 hour flight was a cookie or pretzels.

My light was not working, I requested a meal without carrots( due to an allergy). It was not provided, so during the 13 hour flight, I was only able to consume bread and a small fruit cup. The air host was not helpful at all.

In-seat entertainment was great. Gluten free food options were very good and they gave a lot of food.

Staff was very courteous and kept things organized. We will definitely use Air Canada for further travel

I am very tall. All airline seats are a bit uncomfortable.

There were a lot of empty seats so we were able to spread out and be more comfortable. The food was decent enough. The crew, however, there was one flight attendant who put a hand on my grandson as he was walking to the bathroom and told him to stop. He’s 13 years old and didn’t need an escort so I don’t understand the necessity of putting a hand on his chest and saying “stop”. My grandson was confused and embarrassed with no explanation.

No food, terms when selling are not clear. To pricy for the service in general

The incoming plane was late and no information was shared. They even announced we would board in 10 muntes 40 minutes prior to the plane arriving, and the website said until takeoff that we had taken off an hour earlier

Boarding was excessively slow. They do it by groups in a way that it doesn’t make sense. After business class , ppl that need assistance and any other priority group they should have ppl board from the back to the front. First rows 20+. Then 15+. Then 10, etc. having ppl sitting in the back board last makes no sense. The libe backame long as soon as ppl on rows 10 or so where told to board. The line went all the way up the ramp and tunnel for 25 mins.

The chicken that was served in business class was cold!

Flight to Bogotá delayed by 3 h Missed connection from Bogotá to Guayaquil. Avianca unable to bring us to Baltra on time Overall delay 36h. We missed boat departure from galagos. Overall 10 day trip needed to be cancelled. Avianca was completely un-professional.

I receive a service for what I pay, so it is fair.

Business class seats did not lie flat. There was only powdered milk for your coffee....in Business Class!! Food was good.

The seats were very uncomfortable. I would have upgrade or got different flight if I knew. I usually sleep in the plane but I couldn’t sleep at all. Very uncomfortable. Also no food or drink everything was to purchase, and that’s u usual for international flight.

There isn't much space in-between seats and even water needs to be paid for during the flight.

Lounge for business was closed. Boarding was rush and stand by. Seat for business is just the middle seat blocked and some more leg room.
