AAAAHHHH... It was shocking in a very positive way, the attention to detail, the courtesy, the manners of all personnel on board, the constant honest smiling. You can see and feel they take pride in all they do no matter how trivial. The plane in general was very comfortable. I can't wait to do it again

AAAAHHHH... It was shocking in a very positive way, the attention to detail, the courtesy, the manners of all personnel on board, the constant honest smiling. You can see and feel they take pride in all they do no matter how trivial. The plane in general was very comfortable. I can't wait to do it again

Great service and comfort level. You can have more of vegetarian food options.

The boarding process was efficient and quick. The seats were comfortable. The food was good. The service was excellent. We had a lovely flight from Seattle on Korean air

Flight crew was fantastic. The aircraft was meticulously cleaned at all times. The crew was continuously checking to see if the passengers were ok.

They were trying to get people to check luggage because the over head compartments were full but when we boarded there were lots of empty places that people could have put the luggage.

It was good, I liked the self-serve snacks but it was a little difficult to get the alcohol, which is understandable since I wouldn't want kids sneaking it.

Friendly flight attendants and gate agents. Very clean plane and food was good!

I was unable to select decent seats, and so I was stuck in the middle seat because it was selected for me

There was a lot of partial tv shows but not enough to last the flight. The food was incredible! The crew were so helpful and patient. Lots more space than what I usually get on an international flight. Very comfortable!

Stingy on the drinks - 15 hour direct flight and could barely get attention for some water

Much better than Latam, the worse airline company ever. I hope I don't have the need to fly Latam ever in my life again.

Seats in Delta Main are unbelievably close to the seat in front of. Hard to get a backpack under the seat.

The flight was operated by Latam. The aircraft had a technical issue and the flight was delayed for the next day. They grounded other passengers to get their airplane assigned to my flight. Most of he ground staff don't speak English (Orlando Airport), but were very polite.The crew on the other hand could speak English and Portuguese. On board service was good.

The agent at check in and at the gate were less than thrilled to be at work. I'm not a fan of Kayak's placement on the plane. I got put in the middle seat and none of my preferences were used.

In ATL they have two sets of departure screens. Follow what is on your airline's departure board - the ATL Airport Authority departure board had completely incorrect details about the gate assignment for my flight, which would have made me miss boarding.

Flight was delayed it was hot while sitting on the plane, one engine was working on the plane until they had to do some jimmy rigging down the runway in order for the other engine to charge up. It was ridiculous

The flight was very good and the staff was very friendly and helpful!

The only thing I would say is we tried to get on a standby earlier flight, but with our fair we couldn’t. That seems senseless to leave with open seats..

Very easy to use and convenient, you can perform any action within the same portal

In a world of delays, Delta was on time both ways! Boarding was fast and efficient. Staff was friendly. AND wifi worked.

Staff was very courteous. Plane was clean and quite spacious even in the last rows. Veg food could have been better.

Later on, when there was no more bottled water, the water we received had a strong chlorine/disinfectant odor. On my flight from Hong Kong to Los Angeles, there was a male flight attendant who had a mean attitude throughout the whole trip, and he was very impatient during meal service “Furthermore, we purchased a Hong Kong SIM card as part of our flight package, but we received no instructions—neither by email nor SMS—on how to activate or use it. Consequently, we were unable to use the service at all. We request a full refund, as this appears to be a deceptive charge

The crew and the food were excellent. The plane was kept quite clean.

Crew were not engaging. Only engaged if requested. Food taste was mediocre

My seat had many issues. First the chair was broken where reclining was difficult. My usb plug was also broken so charging was impossible.

The flight from Hong Kong to Hyderabad didn’t have any power points to charge my mobile. Given we are no longer allowed to use power banks, giving customers the ability to charge even on short flights is critical part of the overall experience.

The flight experience was good for a long flight over the pole, but it got my wife to the Far East in time.

when i ask for help all the crew members had a look like why are you calling me? very terse and rude.

Good service and food. However, we paid over $400 for aisle seats for my disabled husband and me, and we were given window and middle seats. This was dangerous for our health condition on such a long flight. We needed to stand up and walk around frequently, but we were stuck in our seats. Please give us a refund of our seat payment since you chose not to honor our request.

Very bad Instead 22 hour it take me more that 35 hour to arrive from Los Angeles to Phuket and they changed my flight in Hong Kong to Shanghai china and in order to get my bag I was forced to vet china visa entrry

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

I booked tickets for a family of five and specifically paid extra to select our seats together. We spent nearly $1,000 extra (around $100 per seat) for extra legroom so we could sit near each other. However, despite paying for this, we ended up being separated on the flight. This caused a major issue for our family because my parents do not speak English and rely on me to translate and assist them during the journey. I do not understand why Etihad changed our reserved seats without explanation. I am extremely dissatisfied with this experience. I expect the airline to do better, and I am requesting a full refund for the seat selection fees we paid.

Flight got canceled due to Middle East conflict. Just fly hasn’t refunded me the money

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.

Kayak and Aran grant issuing business class tickets without lounge access and sometimes 1 or 2 connections in economy class. It’s very disappointing to find out that after buying the ticket. Never buy tickets on kayak and Aran grant again

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!

Was so disappointing. Business class with no TV, uncomfortable seats. Had much higher expectations.

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

It’s a business class ticket but they didn’t give a lounge access
