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.

I appreciated the fact carry on picked up at the checkinn . Service and check in super nicer.

Crew was great. The crew that came on in Montreal helped us look for a lost passport and could not have been nicer. Our only problem was boarding in Barcelona but was due to airport issue. Not enough staff to get wheelchair passengers to gates.

The flight was cancelled and they lost my luggage which now 5 days later I still don’t have. They gave me food vouchers that did not work so all in all terrible expy

We were sitting in the back of the plane, and they ran out of some food by the time they reached us (last). We didn’t pay less than others so we shouldn’t be treated as lesser for sitting closer to the back. Also, there was a very long baggage check in delay (1hr +) at CDG due to luggage belt malfunction with over 100 passengers affected, yet boarding and take off remained on schedule. We nearly missed the final boarding despite being at the airport 3+ hours ahead of our flight

Flight attendants announced that the flight had engine issue and they could not find the tool to fix it. Passengers stayed on the flight for hours and they announced that they found the tool, but not sure how long it would take. So everyone got off the flights they issued lunch vouchers by using boarding pass, however, mine didn’t work at all. The flight was delayed for more than 4 hours! They rebooked my connecting flight with only 1 hour connecting time, and the 1st flight was delayed again. How worse could it be? I’m glad the engine actually works and everyone is safe.

There should be a visible sign of Air Canada, because I walked all around and I didn't notice where was the desk, I was in a rush for the time because it was very difficult for me to find the D gate.

Older interior meant less luggage storage space. Service was good. I was in business class. I receive better service from other carriers

For me and my wife was wonderful everything perfectly, Tankyou.

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.
