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.

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.

NO HELP FINDING PROPER CHECK-IN LINE; STAFF PERSON WE FOUND WITHIUT ANY SIGN WAS ACCOMADATING

Seating too tight, no way to reclining No USB outlets

They ran out of food and on the flight back to NY there was no wifi nor any socket to connect your plug to charge your phone. Also the crew was not friendly as they did not want to throw out my empty water bottle after she told me to hold on to it and then said no.

Boarding slow and chaotic. Food was terrible. Flight attendants were nice. Sears were comfortable.

food was terrible on the plane, bring your own food, its not worth eating.

I feel like the boarding process could be a little better. But the staff and everyone does a really great job.

Flight was good. Would be great if we had free WiFi

Flight was late, and not sure why. The business class lounge in Porto is not proprietary to TAP, and is really substandard, almost as bad as "The Lounge" in Boston. It was a D, which is better than the F experience in Bostonm where we left "The Lounge" for a better experience in the terminal. It had better food (an extremely low bar), ok beverages, and wasn't as crowded as the Boston one, but no restrooms. To use one, you had to leave and go downstairs. There's no down escalator, and the elevator might be able to crowd 4 people. Otherwise, you're carying your bags down the stairs. I hope the Lisbon club is better, but for TAP to provide this in the 2nd largest city in the home country is disappointing. They put out an announcement to proceed immediately to the gate, but there was no plane and few seats. from the lounge, 8 people with bags waited in line for the single tiny elevator. After almost an hour of standing, we finally boarded. TAP, at least on this plane, doesn't offer a welcome drink to business class passengers. Having said that, the crew was very friendly and accomodating. We landed about an hour late and then were told we were going to be on the runway for at least a half hour because no gate was available. So, bottom line, D- for pre boarding, A for flight attendents, B + for business class food, and Incomplete for post landing.

The worst thing was baggage claim. In my return flight I was waiting 90 minutes for my baggage. and when I asked the airport they said it’s the airline. So frustrating after an 8-hour flight.

Spacious (space to extend your legs and not feel crammed) and good entertainment and decent food!

A marvelous flight experience, from boarding to landing. The full length stretch out seating was excellent. The meals were some of the best in-flight meals I have ever experienced. The cabin attendants were thoughtful and kind. One of the best flights I have ever taken.

We are extremely impressed with all aspects of flying with Air Canada.

The air crew were nice and friendly and the flight itself was uneventful. ATC control delayed our departure for 90 minutes, It was chaos in Montreal for those making connections but the AC ground staff did a good job helping.

The food,information about luggage when they change your fly Still waiting for my luggage after 3 days The crew have no idea how to direct you with information

Boarding went relatively smoothly. Crew and flight attendants very personable and smiling (I like a happy crew). There were no issues from beginning to end.

Our flight was cancelled. We are still stuck in Canada. Rebooking is a nightmare.

We were loaded onto a bus from the gate, that remained stationary for at least 20 min. While the doors remained open, it was still warm and very close quarters! There was no announcement as to the cause of delay.

The crew was Very friendly and kind even when my 2 kids starts to cry because the long journey to Montréal

Flight was delayed for mechanic difficulties. Then flight was cancelled. Rerouted with Air France. No vouchers for food - 9 hour difference. No communication. Ticket was reserved, but not assigned. After going through the Air France line, redirected to another booth to get an actual ticket. 10 hour layover in Paris!!! Had to buy lunch, dinner, snacks, hotel overnight, Uber drivers and no word from Air Cañada… after 1.5 hours of waiting on the phone for “customer service” told to fill out a complaint on line. Will never book with Air Cañada. Also, the airport hub was the most overpriced, limited restaurants available. $15 for a glass of wine and the give you a $2 service charge!!!

The worst airline. They cancel their flights left and right, if they don't cancel them, they are delayed. They only offer you accommodations for a fraction of your stay, then you are on your own. Because of one cancelation my whole trip was a mess. I was stuck in Canada for 4 days, not able to get to the U.S. Once I thought I was going to be be able to get to my destination, their pilot was not able to land the plane because of the weather or find a nearby airport to land so what they did? Theu took us back to Toronto. I had no clean clothes left, I was desperate and stress out and I had to get any flight out of Canada in fear I was going to have to saty another 4 days in Canada. NEVER AGAIN. There are no other airlines in Canada which makes it almost impossible to get out of Canada unless you flight with them.

I didn’t buy any food and there wasn’t any entertainment provided. There were outlets to charge your personal electronics, which was great.

Bumpy flight (lots of turbulence) but the pilot did great in letting us know ahead of time and flying through it. There was no food/beverage or entertainment available.

The crew was friendly. But boarding was disorganized (passengers with kids or needing help were scanned first, but not given actual boarding access first). But the worst part was the plane’s air conditioning was either not working or set poorly. It was a stifling, hot flight. Extremely uncomfortable for everyone.

Everything was fine. No complaints. It would have been nice to get a drink w the flight. Also I would have liked notice that no meals were included beforehand.

In a 6 hr flight after paying over $700 dllrs of ticket and we still needed to pay for our own food and given ONLY a small glass of water!!! Will not be flying internationally anytime soon with them They are good for very short flights

No food was served on the flight. Boarding desk open two hours before departure. But they recommande to be there three hours before departure !! So we where a group waiting 1 hour in Line for nothing …

They charged us 100 Euro per bag on the return leg with no explanation.

The facilities at PDL are absolutely appalling during a 4.5-hour connection. Passengers from multiple flights were crammed into a small area with insufficient seating and only a snack bar. The only bathroom was unisex, with one stall for men and another for women side by side. This is for hundreds of passengers. The connecting aircraft from PDL to JFK was downgraded/switched out to an Economy Class-only configuration without explanation, even though the aircraft with Comfort Class we arrived from FNC on remained at the stand. Those who paid for Comfort Class could not enjoy the better seating or catering. Food and drink aboard was sub-par. I would qualify it as one of our worst travel experiences in years.

The crew was great. The only problem is that electrical outlets were not working in what seems to be a half of the rows on the plane. Considering that passengers are asked not to use power banks, this leaves us out in the blue without any entertainment option.

Flight on time. Staff pleasant and responsive. Food could be much better. Snack before landing was a few dry crackers and a drink. Nothing else. There was a very lumited selection of beverages available on a 7 hour flight. No soft drinks, even in the front cabin.
