Cabin crew on our flight showed lack of any customer service gruff and acting annoyed if you asked anything and I mean anything Example a man on the seat over dropped his beer on my husbands blanket We asked if we could switch out blankets cabin crew Said. No we don’t have any extras OK well can you take the wet one Cabin crew looked disgusted and annoyed Took it no OK or yes just a growl

Quick flight. But cabin crew were very noisy and talking too much, especially when we were seated at the back of the plane trying to sleep through the night .

My ticket was for Premium Economy and all the seats were taken, I was placed in Economy class and I’m looking for a refund.

Unfortunately delayed 2 hrs due to faulty tyre.. which had to be changed, but better safe than sorry.

The delay was an issue. Other than that. Every thing good

Hi vergin Atlantic service was good but the flight ticket agent travel up charge me extra 57 pounds as a airport charges, actually I refuse to pay but they say if I not pay £57 then they say you will not be able to travel from Heathrow to goa ,so for me there was no option and it was just 3 day before my departure so i paid, so please look in to the matter. And I have a receipt of £ 57 as well .thanks

Staff didn’t check cabin well for landing seemed more interested in chatting to each other. Food was poor and differed from pre order.

We were in the last group to be called to the flight - which was 30 minutes late taking off. While we were lucky enough to have been given bulkhead seats (due to a medical condition I’d told them about beforehand) the seats weren’t particularly comfortable. A crying baby for the whole trip made things worse, so the crew managed very well with coping. The final thing I’d say was that there wasn’t enough food served during the flight.

Very good. Glad we had Premium for the flight out.

We flew Upper Class from London to The Turks and Caicos. Check in was amazing. Our ldriver too us directly to a special entrance to terminal 3. It took 10 minutes to check in and clear customs. Amazing! The VA lounge is large and comfortable. Boarding the flight was easy and without a wait. The crew was excellent. But the seats were awful, strange and uncomfortable. Having a comfortable flat bed seat is the reason we pays 1000s extra. The VA 787 uses a reverse herringbone configuration. Look it up. You have your back to the window and are facing the aisle with no privacy. Turning the seat into a bed requires assistance from the crew so not very spontaneous. . The food was ok. A bit tasteless and meager portions. Had to pay for WiFi. I believe VA has other configuration on their dream airbus flights. Lots of stuff about all this on YouTube where you can see what I have been describing. I can not recommend taking VA on a long flight with these seats.

The check in was horrible. I stood in line for 1 hour to check in with an Air France ticket. Then I was told I had to go to Delta counter onstead to check in instead. It made no sense.

Old cabine without flat bed in business for a 12 hour flight is not acceptable

Excellent apart from transport to actual plane 10 minutes from the actual gate , walking out in the tarmac in the rain and having to climb stairs to enter while holding luggage.

They wanted to close counter although they did not provide the wheelchair requested which ended by going alone to transit security and lost long time and they did not want to wait .

Did not find the wheelchair that supposed to assist and went to a long queue for transit security chk which was very slow and boarding desk wanted to close counter although that they knew that I am minutes away because of their mistake of not providing the wheelchair.

Boarding was smooth and on time. The seat was comfortable and the entertainment worked. Staff were gracious.

Business class in the second leg - CDG-EVN was a disaster.

I have used Air France and KLM many times it will help if they change their menu's feel like it's been the same for years!!!, Especially the breakfast. Overall the flight was good and enjoyable.

No birding was given for next trip on same carrier, food was very moderate.

The line at boarding was not well organized and managed

Fine. Though no food or entertainment so the survey needs to be updated with those options.

Backpack should NOT allowed put in the flight bin , only put it under the seat. I can't find space put my carry on luggage!!! and I pay for it ! that was very bad experience

Standard flight experience, but there is only power at the seat to row 20 on the aircraft, on my initial check in it did not say that was the case

I feel like they have upgraded the app since I last flew United and I found it to be super helpful. I had stopped flying United unless absolutely necessary and my experience on this trip indicates they have been working hard to improve their services.

The food that was offered based on class level of your ticket was absolutely ridiculous and disgusting. They didn't even hot tea to serve, the food was horrible. On our departure flight I was seated in premium plus economy and considering the cost of the flight the food was literally some of the worst I've ever eaten. On the return flight I sat in economy with extra leg room and was given a thin little throw "blanket" and a flimsy little pillow. The air condition was on artic and the seating arrangement wasn't really worth the money. The seat didn't recline good enough and the foot rest was laughable. Total waste.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the room where it was being kept.

The ride was good but no food ot entertainment hence, it was just over an hour flight.

Aircraft has better leg room than any of United's larger planes. We had requested mobility assistance for this and related flights. United's response to all was superb.

No snacks served! Seating in the kast row in uncomfortable.

Flight was fine, it was delayed but only 30 minutes, staff were efficient, lady making announcements at LAX was really hard to understand but the rest were great.

My flight was from Charleston, SC to Halifax, NS with one layover and the same on the return. My flight to Halifax was good! The employees at check-in were helpful and friendly. No issues there. My each leg of my flight to Halifax was pleasant. The air crews were excellent, professional and courteous. Arrival in Toronto was uneventful, and the gate agents were friendly and helpful. The same for my flight to Halifax. My return trip was not so pleasant. The flight from Halifax to Toronto was great, with everything I mentioned above: friendly check-in staff and gate agents and quick boarding. It is when I got to Toronto that things went off the rails. In short my flight to Charleston was cancelled about an hour before boarding due to weather in Charleston. I received a text stating I would be rebooked within the 1/2 hour, and I was... on a flight at 6:40 pm the next day, more than 24 hours out! I absolutely could not stay in Toronto that long as I had to be back in Savannah for work. I went to the Air Canada service desk and here is where it really came off the rails for me. Please understand that up to this point every Air Canada employee I had interaction with was wonderful. However my experience with your service desk left much to be desired. As I stood in line with about 30 other people one of the agents announced that for those of us whose flight was cancelled that we had been rebooked, and to please follow her so we could be "escorted out". I turned to someone in line and asked what that meant, "escorted out"? They had no idea. As someone who has limited international travel experience I had no idea what to expect. One of the passengers asked her about accommodations, and was told basically that the cancellation was due to weather and therefore not Air Canada's problem (paraphrasing, but that was the message). She then proceeded to herd a group of passengers to be "escorted out". No other explanation. I waited in line to talk with one of the agents, and happened to get the same agent who had just taken the group out. I told her I could not wait for another flight 24 hours away and asked if they could try and book me on an earlier flight. She handed me a card and said there was nothing they could do and to call the 800 number to try and get another booking. She was extremely short with me and acted as if it was a bother to answer my questions. She said that I needed to be "escorted out". I asked her what does that mean? She explained that the international side of the airport closed at 10:00 pm and that we could not stay in the terminal overnight. I then asked her where I was going to be escorted to, to which she answered "the curb". The curb... outside of the airport? Yes, the curb. That was all she said. I left the desk to call the 800 number to rebook my flight. The gentleman I spoke with on the phone was pleasant and very helpful, and was able to get me a flight out at 7:55 am the next morning with a connection in Chicago. Absolutely wonderful experience there. I then proceeded to walk through the terminal to find my way out so that I could get a hotel for the night (another $225 I was not expecting to spend). I didn't realize that I could not exit the terminal without being "escorted out". I, and several other passengers, found our way at the far end of the terminal which was, apparently, closed to all except domestic Canadian travel. We were not aware of this. We were approached by a young lady with Air Canada and told that we had to turn around and we were not permitted in that section of the airport. She was abrupt and quite rude about it. Not a pleasant person. I made my way back to the service desk so that they could escort me out. About an hour after getting my flight taken care of I received another text that my morning flight had been delayed by 45 minutes. Not a huge deal as I was able to make my connection in Chicago, but it did put me on edge expecting another cancellation. My flight from Toronto to Chicago and then to Charleston was with United Airlines. The flight to Chicago was pleasant. I was fortunate enough to have a seat to myself. The flight from Chicago to Charleston was on a smaller plane, two seats each side, and the individual next to me was not a small individual. I had to press myself against the wall of the plane as I had zero space. Other than that the flight was fine and, again, the crew professional and courteous. I hate to complain because I know that airline employees, both on the ground and in the air, deal with some crazy things and many unpleasant passengers. I get it. I am in hospitality and I absolutely understand, and am appreciative of your associates and the jobs they have. It's not easy and, I imagine, quite stressful at times. Every Air Canada associate I interacted with was wonderful and do your airline credit, aside from those that I just mentioned above. It's not hard to answer a question, even if you're having a hard day. I also understand that things happen that are beyond the control of the airline. Weather, mechanical issues, passengers acting up... I totally understand. When it is all said and done Air Canada got me home safely, for which I am most grateful, and I am grateful for all of your associates who were professional and courteous during my journey.

Unable to initiate refund/reschedule the ticket #worst experience #lost 900$

Horrific, we bought our tickets 6 months in advance and paid extra for specific seats close to the front. There was an equipment change to a larger plane ( more seats), identical configuration, you would believe they could honor the seats we purchased. Unfortunately not, and they sent multiple alerts from 11pm to 2am, keeping us up all night. Eventually my husband was moved to the back of the plane with 40 rows, 10seats wide, 🟰 400 people ahead of him to deplane. ( we had a time constraint we had to catch on landing) I don’t mind a middle seat if it is my husband or travel partner, but if I thought there would ever be a chance we would be separated. I would choose an isle. There was no one we could contact as we were at sea, with no cell service. Once docked, We went to the airport an extra hour early, no help at all Air Canada check in counter told us we don’t work for air Canada, call Toronto. Horrible service all around. When you pay for seat selection, don’t count on it with Air Canada. ☹️

Flight was delayed for almost 3 hours. Communication of gate change was poor. Email and screen said one gate and it was a different gate from that. Gate changed first to 64 B and then to 64 C. Originally it was 68B. 64C was not communicated properly!

Didn't like that we couldn't be seated together or seated away from the stinking toilets or check in on line. All rather poor.

Flight attendants were great. The food I ordered was actually pretty good, and I appreciate the non-tuna snack. That long of a flight in those chairs is just brutal.

This was a red eye return, so I doubt there would be anyway to make it better. Other than adding beds.

They changed my flight twice. The 2nd time they changed it they did so the day before the scheduled departure and replaced the lie flat seat in a 777 to a 737. I paid extra to be in the 777 only for them to change it. Then the departure was delayed twice. The connecting flight was also delayed.

Direct nonstop flight was great. Flight was delayed and the crew announced a 2h delay on the sound system. 30 min or so later I hear my name on the sound system for immediate board. Several other passangers were late too. Reason: The crew incorrectly announced a 2h delay when in reality they meant a new boarding time at 2pm.

Flight was on time early arrival better entertainment good staff.everything was excellent

Loved the food (vegetarian in our case). Super pleasant. We're in our 60s/70s and not speedy anymore but I never felt rushed. Entertainment choices very current, personalized, and fun. Asked to change seats with a man who had paid for his seats as well but something had occurred in process so he was two rows away from his small daughter. Staff was very efficient at mediating the exchange and gave us a beautiful little travel pack as a gift to agree to it. The seats were comfortable but reclined a bit much for my comfort. I'm glad I'm not claustrophobic as the person in front of me reclined to the max and I felt very enclosed. Very efficient crew simultaneously as super pleasant.

Boarding was a zoo. London ground crew was useless. Poor communication regarding where to line up. We were group 2, and everyone was jammed in together. Ground crew didn’t seem to care.

boarding needs to be streamlined load the back of the plane first

Horrible flight attendant in back of economy that screamed at me, have already reported to United. Horrible food - for Gluten free, why would you assume the person is vegetarian? I was served some kind of horrible curry bean paste and multiple cold rolls and soggy vegetables with no seasoning... um no!

Overall great flight experience- on time, lots of food and movies.

I was at the airport on time , I checked in my luggage . The plane was delayed and the gate was change. The flight board did not give information . I did not get chance to fly. I am going to make a claim for it

We were helped whenever needed and had a pleasant flight.

Air Canada from Edmonton to Toronto was disappointing but Lufthansa from Toronto to Frankfurt was excellent.

It was a short flight, no real service (which is okay). Very bumpy because of weather.

I'm Canaadian. I hate Air Canada. I used to give them a pass on their international service. No longer, They suck across the board now! Old planes, exhausted staff bad food and shitty entertainment. Your seats need reupholstered! Start with that...
