The dinner was bland and boring, but the economy seats were surprisingly comfortable. The flight was very packed.

The dinner was bland and boring, but the economy seats were surprisingly comfortable. The flight was very packed.

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.

I didn't have any problems during my flight. My main issue is with airlines in general, they keep offering less and less every year, AirTransat is no different.

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.

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.

They never sent me a confirmation to say my flight time had changed so I cut my holiday short by 6 hours Had to pay over 50 American for my luggage to be checked on the way home and that’s more that it cost on the way there. Arbitrarily charging more for the same thing when the passenger has no options is shady The cabin was an icebox going there and back, if all the passengers have their gloves on and their hoods up that should be an obvious sign to turn up the heat

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 food was very good. I was nit expecting a meal on a red eye trip. I was pleasantly surprised! Plus we arrived a few minutes earlier than expected!

The crew was excellent. The turbulence was very bad and they were unable to serve our dinner. The captain informed the passengers that we were going to get water and snack instead. They provided us ample snacks instead. Otherwise the trip was good.

Despite travelling ultra basic for the first time due to such increased rates we both managed with one bag each. Even boarding last wasn’t SO bad.

There was no food but a singular cookie for a flight that was over 5hours??? Yeah not fun I was starving and again super cramped plane and you guys need to get planes with screens too, WiFi is nice but common we need more

I loved the fact it was on time and it was a smooth flight to my destination.

I like that we landed safely and that my dog was safe underneath as well. Outside of that, we were 45 mins late for a direct flight that is 1.5 hours long. And 2 of my 3 bags did not make the flight. Only my dog was onboard.

Service was okay except attendant over served alcohol to passenger and passenger got tipsy and made me uncomfortable

Food was not inspired but was satisfying. Same for infotainment selection. You’d think business class would come with complimentary WiFi. Crew was uniformly attentive and excellent.

Could not make the flight. No one would help us at all

Decent entertainment although my wife was not offered any ear buds so couldn’t enjoy. Real issue was the appalling food. Presentation was unacceptable with cheap hard to open packaged bread, plastic cheese again in hard to open shrink wrap, main course in small cardboard box again hard to open, wooden utensils which lack substance making the whole experience poor. Surprised I didn’t cover myself or neighbour as the food moved all over the place. Breakfast calzone was dry and unappealing with the staff basically throwing them around. Very disappointed

Didnt make it on flight. Flight was delayed. Then had to get rebooked for a flight that was 8 hours later. Guess who had to wait for 8 hours at the airport?

The flight was smooth, the plane was spacious and clean, the staff was kind and the food was decent.

Pretzels were a bit dry and dusty, however it is nice to have a choice between sweet and savory snacks.

The TV screen at my seat was not functioning for the entire duration of the flight. I informed a flight attendant about the issue, and I was told that I would receive a voucher as compensation. However, I never received this voucher afterward. I therefore kindly request to still receive the voucher that was promised to me.

Flight crew was great, and even the crew for checking bags! I had a question for a friend of mine flying tomorrow and the man I talked to was awesome and answered my questions and looked up things for me when he didn’t have to! I was able to give her current & accurate info for her flight and she was so appreciative too!!

As mentioned before the fact that my paid-for aisle seats had been changed to non-aisle seats is unacceptable. Happily one staff member at the boarding counter did correct it before the flights, otherwise I would have been forced to submit a formal complaint. If it happens again on return flights, I will put in a formal complaint.

Another good flight experience with Air Canada. The business section did not feature the full length sleeping arrangement, but this was a shorter trip. The food was excellent. But the flight crew was truly top tier: friendly, cheerful, helpful at all the right times. Air Canada truly outshines all U.S. carriers.

Everything could be better, the worst is the crew, looks like they are not happy in the work. Air Canada is downhill for years, every flight looks worst. Hope they can fix the issues, by now, just flying AC in toutes with no other alternatives. Shame.

This was my second leg of my trip and was delayed so was worried about my connection in Montreal. Still hungry so on boarding I asked a flight attendant if I could use my $14.00 voucher on the plane for food as I was starving. She said she would check and let me know but she never came back. So no food again as none was offered. Had to get my bags and check them again and that was ok but don’t understand why I had to go through security and because of them almost missed my flight. No food offered nor possibility to purchase food so still hungry and just watched a movie and hoped I could get food when I landed. Was able to use the $14.00 voucher to buy something and had my family bring food as I was now starving. I’ve been travelling on AC for years and this was my worst experience ever. After our flight got cancelled in SXM and was told the staff there didn’t work for AC so couldn’t do much to help us was not a good experience

Staff looked unprofessional. Sloppy uniforms and hardly a smile to be found

Yvonne, was the flight attendant in my area. She was INCREDIBLE!

I never got to Lufthansa because of Air Canadas negligence.

Not great!!! Seats in Business class were horrible; no cushion!!!

Terrible. Lost our luggage for 4 days. Did not advise passengers there was a strike in Barcelona Airport and had zero personnel on hand at airport to advise passengers on where to go to file claims. We had to fend for ourselves. No assistance at all other than an online claims submission process that we had to find out about on our own.

The flight got delayed 3 hours from Montreal and we missed our connecting flight so it was a long journey

Not great - seats were very narrow and food was terrible.

The service and food was excellent. The remote control for entertainment did not function properly.

All was good, except my USB charging did not work, so my phone got drained and I could not charge it. Same happened to my neighbour.

A bit more space? Not practical, I know. I felt squished in but part of that could have been the man sitting next to me.

They didn't open the Check-in desks for almost an hour after they should've been open (even though encouraged us to check-in our carry-on luggage because it was going to be a full flight). They alerted us that the flight would be delayed but slow-rolled informing us of the extent of the delay...which ended up being over 3 hours. As a result of this, I missed my connecting flight and had to stay over-night in Munich when it would've been a lot better for me to just stay in Warsaw another night....Lufthansa wasn't done with me yet though as I had more bad experiences with them after getting to Munich.

Everything about the flight is better,just to work on the food Everything about the food is very poor

All good, professional service, and arrived close to on time.

This was a special trip so we booked first class. It was obviously an old plane as the seats weren't that comfortable or spacious. We were delayed 45mins taking off as the "little engine that starts the big engines doesn't work". The powered divider between myself and the next seat in first class didn't work and my electrically powdered seat didn't work so I had to move seats to try and get some sleep. Food and drink were good, crew were great. But I'll never fly with BA again.

I liked the air hostesses, but no wifi was available for flight. my original flight was canceled and rebooking was difficult and no reason was given for cancellation. Business class cabin was nice and spacious.

Waiting area not big enough for all the passengers, no airport lounge.

My experience with British Airways was fine and dandy. Nothing truly negative to report. However, I was. asked to check my carryon bag all the way through to my desitination which prompted some huge problems. Thank goodness I kept a foldable-personal-item-bag in my carryon. I was asked to remove my valuable electronic belongings from my personal item bag, which was a camera bag full of expensive lenses and camera equipment, into another bag for the flight because it was "too big". Farbeit from me for asking further questions, but the bag was let through when I departed to Paris from America with no problems at all as I was able to explain that it was slightly oversized due to being a camera bag with a layer of protective foam which made it slightly larger. Still, this bag could and did fit perfectly under my airplain seat during my departure from America. On the flight back though, this was not the case and I was asked to remove highly valuable personal items, stow my camera bag in my checked bag, and then had to pay and overweight fee. Kinda bogus, but I was tired and wanted to get home so I complied. Regardless, it would have been nice to have had my bag retrieved during the London to Pittsburgh flight so I could put on new clothes and freshen up before take off.

Very please with the seating that the Kayak staff booked for us!

the service on Business class should be improved to be at par with industry leaders like Cathay Pacific and Singapore AIrlines. A lot of room for improvement.

My experience with IndiGo was terrible. I had tried to check in online. I could do the DEL to LHR and from LHR to JFK. However, I was unable to check in for the CCU to DEL flight. There was no explanation of why I could not do so. After 2.5 hours of being shuffled from one place to another, I found out that because I was on a codeshare flight, I had to get my boarding pass at the airport. For 2.5 hours, no one was able to explain this to me.

Really appreciated the care, attention and friendliness of cabin crew. Very comfortable, prompt and efficient flight.
