Airline reviews

On one of the flights, the situation became sufficiently frustrating that a passenger openly expressed their dissatisfaction. Despite these complaints, we did not observe any meaningful improvement or receive an adequate explanation. The fact that members of our group experienced similar conditions on two separate aircraft is particularly concerning. We recognize that cabin temperatures may vary during a flight; however, the prolonged discomfort and the apparent lack of an effective response significantly affected our travel experience. Passengers reasonably expect a long-haul international flight to provide a tolerable cabin environment. When multiple passengers raise concerns about their comfort or well-being, those concerns should be acknowledged and addressed professionally.

Good. Mm to I am always generally satisfied with Air Transat! 👍

Arm rests are too small and too close. No screens, movie selection was very limited and poor. Food is pretty much overpriced cheap convenience store food.

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.

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.

Onward flight was okay. return from Lisbon was poor as we missed our flight due to a long line at the passport control. Air Transat made no effort to accommodate us even though we were at the passport control 40 minutes prior to the departure.

Thank you for making my first experience very enjoyable. You made it all very pleasant

Great flight great seats will absolutely fly with you again

YUL AIRPORT is the worst. 1 Hr to Get out of the plane, 1 Hr To Cross the Border. 1Hr waiting to be pick up curbside. Trafic is ubeliveble.

The food was small portions and not fresh. I was seated at the back of the plane so by the time the cart approached me most of the food options were sold out. The cabin crew was fantastic however.

Great, the item that impressed us. The most was the fact that some of us were gonna have a tight connection and the crew invited those people with the tight connection to stand up and leave the plane early. Great idea and it worked for us

All went smoothly from Miami to Montreal from boarding to arriving to Montreal. Flight left on time and arrived on time.

Over all good except the food was not good at all

It was pretty good. It was my first time using the airline I believe but it was a relatively pleasant experience.

My flight got Delayed due to the airline. The attending Crewe in Montreal were not super helpful and I arrived 13 1/2 hours late from my original arrival time. Air Canada lost my luggage, they stated they booked me a hotel room overnight at no fee, however when I arrive to the hotel, there was no reservation. It also took me three different attempts to get the hotel, even covered by Air Canada as they were arguing that they were not responsible for this, despite it having been delayed due to the airline. Overall, the service was very very poor and what should’ve been a short five hour trip turned into a 13 1/2 hour saga with me, spending a night in a random airport overnight due to Air Canada’s errors, and searching for my luggage until 2 o’clock in the morning. I will never fly Air Canada again.

$2600 for the flight with food then not even a dog will eat specially breakfast

Air canada charged me for a carry on bag that I did not have.

Our connection flight was cancelled due to the crew being detained in customs for drug trafficking. Ruining my last two days of vacation because they cancelled the rebooked flight too. Worst experience of my life, i want my money back because nobody can give me back those days and reservations i had planned for 6 months.

Smooth on time flight with standard AC service. As usual food options awful. Wish airlines could offer better quality food services

No blankets provided, no meal or snack service provided for a 5hr flight. No headphones provided, available for a $4 charge, no Bluetooth connection to entertainment system provided. Terrible airline.

We booked seats next to each other. When we got the boarding passes, they were for different rows. The crew were reluctant to help us, so we ended up sitting separately. 1. What’s the point of reserving by seat number if you’re not going to honor that reservation? 2. Even if it gets messed up between reservation and boarding, how is the crew going to deny us the opportunity to arrange to sit together. There were plenty of people flying alone. It could’ve been easily accommodated. Not very customer-friendly at all.

Seats are absolutely not comfortable and large enough. There’s a limit and you stepped over it. I understand that there’s a business class, however for the price it costs, it’s just plain stupid for a 50 minute flight.

The employees at the gate were not communicating, they preferred to give the upgrade to pilots and not to the elite passengers Every flight I more disappointing, clients shooed be priority instead of other employees even if they are pilots, there was plenty room for pilots in economy

I had bad experiences before now was excellent I am glad they have business class again

Provide free food and drinks on an international flight. Add updated head rests

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.

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.

Our flight from BOS - BOG was delayed 10 hours because they were waiting for a Flight attendant to fly from Miami. They lied and said they would give us food and hotel. That was a straight Lie! It never came! We were in the airport for 13 hours with Two babies. We were on the plane 7 more Hours. When we asked to get diapers from our checked luggage, Jorge in Boston told my wife she should have planned better. Meanwhile, the 10 Avianca Employees Sat there and did nothing for 13 hours. Yes, we planned for 10 hours with the wait and the flight, not 20 hours JORGE! If this was an American company we would have got a refund! But they are not up to American standards. The kicker is they apparently needed the 3rd stewardess to serve the food. Guess what? It was 4AM when they tried to serve the FOOD! Everybody was asleep by then! Ridiculous! Never Again!
