They shld improve and provide a lunch or dinner in an international leg

The crew was great and the food and liquor offerings were good. Seats were a bit cramped. Flight arrived early at destination. That's a plus.

No separate queue for business class/platinum passengers. I had to stay in the long queue to board. I requested breakfast before landing, but the crew didn't offer, except a coffee with milk. No tea with milk was available. Had asked for cookies, but didn't receive them. The crew in the business class was not good in terms of service..

I didn't understand why I got dropped off at departures on exiting the plane at Doha aiport. I had to find my own way to immigration/baggage reclaim which wasn't easy as staff in the departure section just tell you ti scan your boarding pass. This was very poor b qatar Airways. I spent 2 hours soyung this out and once I got to get my suitcase it was delayed. So instead of getting to the hotel at about midnight I got there at three in the morning. I wonder why I upgraded to business?

Polite and helpful crew. My son developed fever. Crew members came and gave him medication and also came and enquired about his health several times.

Boarding delayed, no communication. I left the lounge, and heard a final call, boarding started after a 30 minutes.

Food and Service inside the flight. Airport service from Qatar is not good mainly because of lack of coordination and not used of seeing so many ppl commuting

Very very poor service. Authorities must take action against this airline immediately. Total failure to follow the rules and regulations of an international airline

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.

If you want to make money pls charge it in the ticket, Chennai check in crew simply forcing travelers make payment for unnecessary. Second, Chennai crew not even listening travelers request. Poor service and not sure you will improve with my feedback.

The crew were great. The boarding process was unclear where to line up. Plane was very old. Flew on a new plane flying from LA to Houston. Business class was great. Plane from Houston to Merida was very old. The plane from LA to Houston made me think I should fly United more. The plane from Houston to Merida made me think I should stick with Aero Mexico and Volaris.

Due to a cancelled flight the day before this flight only had 44 people. Best flight ever on international route. Food getting better. Can United provide fruit ex apples and bananas for snacks? Crew fantastic.

Sitting in row 31, you could smell the bathroom during the entire flight. It was pretty disgusting.

I like the food, the entertainment, just more room on the plane

Too short a flight to have service offered. A free simple snack offer (eg, biscuits), as in the old times, would have been nice.

Good flight I loved the 2,3 ,2 seating.Staff were excellent plenty of food and drinks

The United website was easy to use and had all the information I needed. I needed to change my flight and it was accomplished easily on line. I was also easily able to upgrade and for a reasonable price. Boarding went smoothly and the flight was in time. The service was good in board but the crew did not seem happy at all. Limited availability of meals - not much choice for purchase and in business class they ran out of one of the meal choices by row 4. .

Honestly didn’t like anything. Crew was in rush . Food was ok and there was no whiskey. Have to pay extra $ if you want to drink whiskey . They only provide wine and beer.

Compared to other international Airlines the infotainment system is need of overhaul. Doesn't have music it's got a limited selection of movies but I was impressed that an American airline was showing the documentary on John Farnham an Australian singer!

Flight was delayed. Connecting flight left 5 people - pulled away from the gate 10 min early with no connection options until the next day !!!

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.

Seats are so small now that if you are in a middle seat, you will likely have your neighbors arm, leg or shoulder in your space. Even in an Economy Plus seat, the width of the seat is only for average people. I’m small and shared my full fare seat with the large man next to me

Flight departed PHL one hour late due to late arrival of aircraft. On board services were okay. First class menu does not offer any new items; same desserts (cheese & crackers or Mango sorbet). At least there were no credit card promotions during the flight.

No service due to turbulence. No entertainment on this type of aircraft. But nice old comfortable seats.

The crew of Flight AA 35 were extremely friendly while being amazing professionals the flight was wonderful all but for the unavoidable problem of space on today’s flights no matter how large the aircraft. I have been flying for nearly five decades I understand that the cost of flying is expensive, maintaining aircraft, cost of fuel, crews, support personnel and everything else that goes along with modern aviation. However, the lack of space for people that are tall or even oversized a little bit. It’s just gotten worse in the last 50 years and that unfortunately makes the flying unavoidably discomforting and not so wonderful. I understand you can buy space in first class and you won’t have these issues but to take Economy break it up into premium economy and regular economy based on the loss of the business traveler doing 2020 to 2023, as a way to regain all of the profits that were lost doing that period. Seems a little harsh to all the folks who have struggle just to afford the fare to fly. So not having leg room is extremely painful on a 15 hr overseas flight. Otherwise American Airlines did exactly what was expected getting me from point A to point B.

The plane was subbed for another last minute, the gate was changed last minute. Could live with that but we boarded and there was a delay which totaled an hour in the end. There was a technical issue which meant wheels needed to remain out for ten mins after take off. My USB phone charger was broken as was the headphone jack which meant I could t enjoy the IFE and could use my phone after a few hours. Even the map function on the plane failed to work after a few hours.

Paid for a first class lay flat seat that was broken, 7 hours of sitting straight up!

First off, I never complained so it is not the crews fault. The lady to my left did not respect my seat whatsoever. She was too big to lower the armrest and basically sat on me the entire flight. She was against the window. I was in a middle seat. For future reference, American, please make sure the armrest will lower or get someone a larger seat/2 seats.

Flight very friendly. Made sure all passengers were comfortable and took care of any personal issues

Flight was a delayed a few minutes but nothing crazy, everything went extremely well

It was very bad travelling with air canada the people working at check in bagages was very bad person any way I pay to much many to get good flights but it’s not

I missed my connection flight, I don't have anywhere to stay I am lost

The only complaint, and it was a HUGE HASSLE, was the carrier of the flight from Newark to Toronto on flight AC 3711. On my itinerary it stated that the flight was 'Operated by REPUBLIC AIRLINES/UNITED EXPRESS'. Translation: it was a United Airlines flight. Different terminal, which meant frustration with inability to check in at Terminal A, needing to catch a shuttle to Terminal C. I told my friend who was picking me up that I was flying United Airlines. She waited for me at the United Airlines terminal in Toronto, except I arrived at the Air Canada terminal. Very confusing and difficult for all of us. Better communication is needed when other airlines operate Air Canada flights.

Flight was good. They offer only soft drinks not even a small snack as most airlines offer.

Air Canada switched my connecting flight to Alaska airlines without any communication to me. The process of finding this out, needing to leave one portion of the airport for the next and what i should have done with my luggage was not communicated to me at all. Even the Air Canada agent that noticed the airline switch at the terminal did not explain this process to me. In doing so my luggage did not arrive with me. The delay to create a claim too 2 hours.

Flights on time. Friendly/pleasant ground and in-flight staff. Better snacks and films with captions,

It was by far the best trip. Cabin crews were fantastic and friendly

Food was great. Staff was great. I would have liked to see more in flight shopping - they went by so fast I missed it. I would have liked more variety in tv shows but overall flight was great. The staff made all the difference.

The bathroom I used could have been cleaner and tidier. Didn't look like it was kept very well. The staff were super helpful. There was an issue with my screen, and they rebooted it for me. They were also great at dishing out our meals, and cleaning up after.

very late flight, small uncomfortable seats. no refreshments except small plastic cups of juice or water, no snacks, no food given, no earphones given unless you pay.who has earphones with jacks anymore? what good are those except for your plane?
