Extremely uncomfortable seats with very little cushioning, unable to recline enough to sleep comfortably on this 13 hour overnight flight. My body was in pain by the end.

Extremely uncomfortable seats with very little cushioning, unable to recline enough to sleep comfortably on this 13 hour overnight flight. My body was in pain by the end.

When we checked in at the Siem Reap Airport in Cambodia, we were only given three boarding passes and told that we would have to check in with American when we arrived in Boston. This was a source of stress for us. After we landed in Boston, we had a long passage from Terminal E to Terminal B (American Airline ticketing counter). Because the electronic ticketing kiosks for check-in would not recognize our Confirmation Code, we had to wait for an hour in a long line where only two AA reps were taking care of Special Services passengers. In many years of both business and recreational travel, I have never had this experience. I would expect more from AA being in partnership with other airlines to do a better job with this.

Our experience on the Doha to Hyderabad segment was extremely stressful due to prolonged delays and a lack of clear communication from the airline. We were traveling as a family, including children, and the uncertainty around timing and next steps caused significant distress. There was very little proactive information provided during the delay, and we were not given clear written explanations about what was happening or how long it might take. This made it difficult to manage the situation, especially while caring for children in a transit environment. In addition, one member of our party was ultimately unable to continue travel, which added to the emotional strain and disruption of the trip. Overall, the experience highlighted gaps in communication, customer care, and handling of unexpected situations. We are sharing this feedback so that future passengers, especially families, are supported with clearer communication and better assistance during irregular operations.

The seat cushions are absolutely lacking, not sure if they know the passengers are traveling for 14 hours straight, but the padding made our back and butt ache like crazy. The entertainment console had its own problems, either the headphone jack wasn't working or the power outlet via usb or ac outlet was not working. Not to mention the seat handles were not adjustable in some planes in the middle or on the aisle. Qatar/Indigo may be operating a very old fleet of planes to make as much profit as possible, but passengers may not be following them for long, should this treatment of its customers continue. Qatar/Indigo, wake up and do it right by your customers, or they may not be your customers anymore.

It would help id flight crew were not rude and showed some courtesy. They were shouting at passengers and yelling instructions as if we were school children at lunch cafeteria!!

All good. Over four hours flight if provided snacks like Qatar Airways would be better

Lobster starter in business class was not good, tough, served cold, and without butter. Movie selection was missing latest releases, did not offer older classic, high quality movies

Food was absolutely pathetic. I wasted so much food which I thought was inedible. I also loathe the inflight entertainment system which has very little content

My entire row did not have power for the full duration of a 14.5 hour flight. Could not charge any devices such as laptop or phones for the entirety of the long flight. The flight attendants tried to remedy the issue by resetting the power, but were not successful. The only other solution provided was to move me to another seat on the plane which was in the middle row. I had paid for a “preferred” seat that was a window seat. This was a downgrade being offered due to the power issue.

Nothing to complain. The staff and flight was good especially the seats which was better compared than the cloth ones on Qatar airways

Food quality and varites were very minimum. Surprised to have no desserts. Business class tickets should have lounge access and seats selection. They should be allowed to board while people with wheel chair, secial assistance and family with childrem.

Dear Team, I purchased a full travel package that included 2 checked bags through you and JustFly. However, when I arrived at the airport, my ticket showed 0 checked bags. Since I was traveling internationally to India with 2 bags, It was a $200 per bag at the counter, which was extremely disappointing. For an international trip, why would I ever choose a no‑bag option for only $20–$30 less? This seems like an error in the booking process, and I am requesting clarification and a resolution. I have called JustFly and on phone for 1 hr :53 min and they couldn't help till I show some kind of proof etc which isn't possible but besides that love your service and using it for years !

Good one but just notice that you have to ask several time to get water or coffee .

Good service. But on flight to Kochi no entertainment except in app. And no working outlets to charge phone.

Good flight. There were a few issues with the flat bed. It was some technical issues. Otherwise everything was good

From the start of my vacation at Logan Airport, Boston it was chaotic. I'm praying my flight home is better .I'm grateful that we landed safe

We have paid premium price for a business class Cabinet and we have received the old 777 with the following apart business class that is not to standard. It was very disappointing and it’s a very bad reputation for a premium airline company. This aeroplane should be the commission from being as a business class. We will pass this knowledge to our colleagues because the quality of business class in Etihad is not consistent and it is a lucky dip that sometimes you’re getting a good aeroplane and sometimes you’re getting their 30 years old aeroplane. The crew of the aeroplane have apologise and said that they hate this aeroplane and they have complained about it multiple times as well. Obviously Etihad is putting the economy in front of the Customer Experience. For the future we will not take this risk anymore and will fly with established company like emirates.

There was not any issues with the Etihad Airways. Staff was excellent and I love the variety of movies and games that they provided.

It was fantastic. The flight from Chicago to Abu Dahbi was fantastic. The crew, food and service were amazing. Everything was handled by the crew member assigned to us , Nicholas, was usually done before we asked for it. Highly recommend Etihad!

I missed my flight ,staff unhelpful, they sat and watched me wait ,gangway door closed, English was a problem no announcement I was on time now I missed my month vacation ,lost 1400 bucks no refund I'm sick to my stomach

Good overall. Seat spacing a bit tight between IST and ISB.

Excellent staff despite some trying passenger situations. Very impressed with their good attitudes and kindness.

Crew were unfriendly, touch screen for movies didn't work very well, seats were tight and uncomfortable

After arriving in Istanbul, the transit information on the electronic board showed a tight departure time, and the gate changed in the middle, making it difficult to make it on time.

Typically good service onboard but baggage delay in airport was significant

My, Syed Zawar Hussein Shirazi frequently flyer membership number was not included on my boarding pass from O’Hare to Istanbul despite my reminder to the attendant at check in. Further she forgot to give me my boarding pass form Istanbul to Lahore and she needs to improve her customer service, please 🙏

Everything about that day was great I was happy with how things went as a first time traveling with the airline thank you for all that you’ve doing by taking us there to our various destinations thanks.

They oversold the tickets by one which was my ticket so I didn’t have a ticket till last second

Not good. I was supposed to be in Mint but got in economy class

Service was slow and checked bag was off last evening when flying business

Flight boarded, departed and landed on time. Excellent service from flight attendant in FIRST

Boarding is always an ordeal. Less dogs on flights. I am highly allergic to dogs and cats. Why are there so many animals these days?

Flight to Tampa was delayed taking off due to plane arriving late but no other issues

There was a delay with the plan which cause the flight to leave later and once arrived in Chicago there was another delay and some passengers missed their connecting flights

Massimo, flight attendant was very authentic, attentive - wonderful. Food/wrap was just okay.

This was one of the most frustrating travel experiences I've had to date. I had changed my flight day of to this one as it was slated to depart on time. It ended up being so delayed that my original flight took off before this one did. The boarding process began but eventually stopped and everyone had to get off the plane as a problem was identified. The person at the front desk just tried to laugh it off as if this wasn't already a huge inconvenience. From there, we eventually got to board only to sit at the gate for an additional hour because of some additional issue. This was extremely frustrating and caused a lot of stress.

It was a little concerning to hear the ground crew arguing with the flight crew over baggage space. Instead of taking them and checking them, they started checking for space in the first class cabin moving items around like the flight crew didn't know what they were doing. I was embarrassed for them.

delayed due to weather. Could not communicate with family since the wifi was broken

I got sick nothing contagious but distressing and the care I received by Kayla? Keighly the flight attendant will be memorable for ever. Thank You

We were told the flight was delayed 5 times, then it was moved to the next day.

We were made to wait in the airport for six hours for a flight that was ultimately canceled.

Both flights were significantly delayed. The flight experience itself was great.

My flight got delayed and eventually canceled, then rescheduled. I and several others had a connection from Boston to Paris and asked several times if we would make it. They assured us we would and then rebooked us mid flight without our consent and closed doors early even though they said they communicated we were a bit delayed. We got stranded in Boston and I opted with being rebooked for a different connection to France since they refused to pay for a Hotel. I've now been in Europe for 5 days and still haven't recieved my bags. There was absolutely no urgency for the fact that I'm in a foreign country with absolutely no change of clothes or any of my medication. Such an overwhelming and frustrating experience.

Automated scanning was slow and somewhat haphazard. Too many people were unfamiliar with the tech and were forced to learn on the fly. The hands off approach of the gate staff made it more uncomfortable. This needs work. Overall the flight and cabin crew were excellent.

The crew for the flight was A+ top notch. They were friendly and professional and made the flight a very relaxing and enjoable.

Rude crew member. She seemed annoyed at me without me saying a single word. Also loudly admonished me for having my bag next to my seat instead of tucked away before landing. Just telling me to put it away and guiding me without giving me a lecture would have been enough.

No included food for a 5 hour flight and the entertainment was only accessible if you had wired headphones (not provided). Otherwise though, great and smooth flying and customer service.

Crew were fantastic and so catering and wonderful! Full score for the entire crew!

Because of weather and mechanical issues our flight was 4 hours late. The only compensation offered to us was a meal voucher to be used only at Boston Airport and only on the day issued. But by the time it was offered to us all the restaurants were closed, so there was no way to use that offer.

Friendly crew, efficient boarding and flight arrived early. Couldn’t ask for a better experience
