The rows of seats in economy class are seriously close to one another making eating and resting just about impossible - there is hardly any legroom. Anyone larger than average size would have an incredibly uncomfortable flight. I had to basically share my seat with the lady passenger next to me as she was too big to fit into her allotted seat.

The rows of seats in economy class are seriously close to one another making eating and resting just about impossible - there is hardly any legroom. Anyone larger than average size would have an incredibly uncomfortable flight. I had to basically share my seat with the lady passenger next to me as she was too big to fit into her allotted seat.

Fly Qatar Airways is always amazing. Their service and care for details is really very good.

Operated by American Airlines. Very chaotic and the crew was bit rough responding any enquiries. Restricted leg space.. Qatar would have been better

I found it weird that the quality of the flight different from Australia to Doha than the Doha to Berlin leg. The quality of the toiletries pack (was in a box from Australia) and then a proper bag from Doha. The biggest variation was the inflight entertainment, which had a significantly shorter amount of content compared to the Doha flight. My QSuite seat was also broken and did not recline all the way flat. Wasn’t the best and I wouldn’t be happy if I’d paid cash for the flight.

Boarding procedures are very tiring. We have to clear security twice for our connecting flights from Doha. Also every time we board flights we have to show boarding passes 5-6 times.

Overall good but staff in the place looked extremely tired after 8hrs in 14 hrs journey and then service was cut short and response time for calls increased in later part of flight. Food was ok not astonishing

Very bad. We booked 8 months in advance for 2 people but couldn’t get seats together. Food was so bad I couldn’t even eat.

The plane from Dublin to Doha was quite comfortable. I was in economy and the seats and rows were very tight. The man in front of me reclined his seat and it made my screen incredibly close to my face and I wasn’t able to take my tray down and my knees were pressed against the seat. I had to ask three times for him to pull his seat up but in his defence he hadn’t even reclined it far, the rows were just too close. I had a pain in my side by the end of the flight from the chairs which were quite worn and not very padded or supportive. It was a significantly inferior plane to the plane from Doha to Sydney and vice versa.

In spite of placing requests for vegetarian food, I didn’t get it because they ran out of stock. According to crew, only fixed number of vegetarian orders will be carried. Typically, they should have checked and served those who had specifically requested. I was one of those to get the food last.

You're like a poor man's Emirates Airlines. The Asian vegetarian food was awful. The entertainment selection was very limited and not contemporary at all. The seats were cramped. There was no plug for charging my phone (I refuse to plug into a USB port - A security risk). The plane itself was aged.

No water on the toilets, dirty sits. 4 hours delayed departure.

Crew seemed annoyed by the fact we were there. Very unpleasant

Frankfurt airport is the worst. Passengers are forced to use stairs to get to the terminal or catch a shuttle. Very inconvenient for passengers who are ambulatory challenged or have physical handicaps.

I have to wait for plane in Denver for three hours. I don’t receive my luggage in Denver. I come back home without the luggage and I wait till next day to see my luggage again. Not really good experience with United airlines. I’m sorry to say that.

There was no screens on board AND the WiFi didn’t work. My seat was broken and couldn’t recline so I couldn’t even sleep. The flight attendants didn’t offer anything to make it more comfortable. It was such an old cramped plane, when the person in front of me reclined I couldn’t even open my tray table. All the United ads talk about guaranteeing everyone gets a screen!

First flight of the day… MINIMUM FUEL! 15 minute landing delay at HOU due to fog turned into a 2+ hour delay! Rather than circle, they had to divert to another city to refuel! Sat on tarmac at Austin to refuel. We ALL missed our connections! The crew, including pilots, were clueless. Crew was really a mess. At HOU, Untied employees were exceedingly rude to all. It was pitiful.

Meals were adequate but could be better. Lots of movies, podcasts, tv shows. We really enjoyed using our personal headsets highly recommended. 15 hrs flight great to travel at night.

I liked everything about the flight. The service was excellent!

The flight was canceled. Got rebooked to Chicago and when we arrived our luggage where to there. They were going to our original destination the day after. They would not deliver them to our house. We had to go pick them up.

One of the best flying experiences I’ve ever had.

not enough crew for business class and not great service as a result. underwhelmed overall

Terrible customer service playing as usual was late and the Denver tried to get to a bus, but it already scheduled for service to Fort Collins, but because they could not help me at all at the baggage service desk. I missed the bus by one minute after they kept me arguing about how to handle my bag which have not gotten onto the carousel, Customer Service and Denver at the baggage claim customer service had the nerve to say she did not fly the plane and the responsibility of the bag was all mine. Pathetic.

Worst experience flying American Airlines. I fly with them often, so I was super disappointed in the service I received at gate 30 in LGA on May 24, mid-day. The flight was delayed twice. I was patiently waiting in the American Airlines lounge when I received the notice on my app that the plane was boarding 45 minutes before its newly re-scheduled take off of 4 pm (from the orginal 1:45 pm then 3:00 pm). It took me 5 min to travel from the lounge to the gate and when I arrived there at 3:20 flight gate attendant told me the flight had closed and that they announced for passengers multiple times. I showed them the notification on my app and they were really rude and unempathetic. The person who rescheduled my flight at customer service wasn't any happier but was at least helpful in getting me on the next flight.

Tray table was filthy when I sat down. I needed to have someone come clean it because there was food and stains on it WiFi didn’t work after paying for in flight WiFi Food was terrible and was not filling at all Chicken was rubbery Flight attendant had an attitude, interrupted me and wasn’t able to answer basic questions about the food selection such as “does the chicken have red sauce in it”. If your flight attendants are not going to know what is in the meals so we can make an educated decision based on dietary restrictions, they shouldn’t be on the plane. My 1.5 year old niece was sleeping and dropped her binkie. I went on the ground under the chairs looking for it. It was at that time that she came up to me as I’m CLEARLY on all 4s with a flashlight and said “I need to get by”. I said one moment please I’m getting something from under the seat (while my head was literally under the seat). Her reply was “no you need to move now” and proceeded to almost push me out of the way. I looked up and all I saw was her toes under my eyes. When I looked in front of me, her private parts were inches away from my face. I then made a comment “you couldn’t waited 2 seconds?” and her response was, “no I need to use the bathroom”. I understand that and would never want to be the reason someone couldn’t get to the bathroom but I was under the seat. She could’ve gone around the other way instead of harassing me, basically placing her private parts on my head and borderline pushing me out of the way. You don’t pay (especially this much) for this deplorable experience. This was by far the worst experience I have ever had on American. I will be absolutely thinking twice and thrice about flying American Airlines again. I would rather pay more to fly delta because at least I know their WiFi will work and their flight attendants won’t have a terrible attitude for no reason, nor will they act the way this woman did. Unacceptable.

The flight was great but board was a nightmare. The gate was changed 4 times during the layover period

Flight was delayed three hours waiting for the flight crew, even though the plane was at the gate for the scheduled departure

Late boarding to clean plane from previous flight; initial boarding announcement not loud enough; fantastic cabin attendant front of plane

It was less than what is expected for a business class ticket I thought that the staff actively ignored me because I either looked Indian or Hispanic to them and I guess I did not deserve their attention. The food which included a beef entree was not available so not enough food was ordered for number of seats available. I will say experience in Greenwich lounge was very good and the staff there at the airport were very nice. May be your crew needs to learn about racial equity so that everyone gets either the same aweful treatment or hopefully the best treatment which is what we expect I recommend you take a flight with Singapore airlines that I have taken and the crew remember your last names and use it to address each person, food never finishes if you are at the back of business class and crew anticipate your need even before you articulate. Same price and 100 times better service than American Airlines

American Airlines canceled the flight twice and was unable to facilitate a change of city for us after our travel plans became affected. We lost alot of money due to this and it seems like the airline was trying their best not to facilitate this. Mind you, I am a very loyal member.

For an over three hour long flight one pack of cookies was not enough.

It's unacceptable to receive your bags after 5 days, and having to call multiple times to get delivery.

Not great tremendous delays instead of arriving at 8:15 pm arrived at 2:30 am next day no food gate changes. Etc

A220 plane had 5 seats across which is great for couples who can snag the A&C seats. Seat itself is borderline comfortable but still tough on a 5+ hour flight. Overhead bins are small so if you're not in at least boarding group 5, you could be in trouble. No included food service. Non-alcoholic drinks are free but even the most basic snacks are for a charge. Price was reasonable for the only direct SEA-YUL flight. Boarding is efficient even managing passport checks. Worth flying for the direct flight.

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.

It was a domestic flight so the food was not included. But we had not even a little snack and by the end of the flight they were coming around serving water.

On the flight back from SFO to Vancouver ..the crew was less than professional. They completely missed asking if I wanted a drink (and I was awake at all times) and I had to walk to the back of the plane to ask for a cup of water to take with my medication. Also, there was a charge for ear adapters for the movie screen which were given out free on the flight from Vancouver to SFO. The flight from Vancouver to SFO had pleasant crew members. What a difference in the flight back.

I got hurt and needed a wheelchair. They were excellent. I also appreciated the fact that they kept me informed thru out the whole trip regarding boarding, gate changes and luggage info.

I got hurt and needed a wheelchair. They were excellent.

Everything is very good, No need to be changed. Thank you

Terrible. We waited for over an hour to get our bags. After a 14 hour flight is was extremely frustrating
