For a 17hr economy flight it wasn’t bad at all, thankfully it wasn’t a narrow body plane.

For a 17hr economy flight it wasn’t bad at all, thankfully it wasn’t a narrow body plane.

Simplicity of boarding and corporate interactions were all totally positive and simple, brief, organized and clear. No regrets at all. I will favor flights with Cathay Pacific in the future.

Big selection and great food and beverages in business class with good service. Full recline but less privacy compared with Qatar.

Really impressed with the Airline and much with the Crew. The crew was amazingggg, changed seats very easily, provided a lot of snacks on demand, the plane is nice and clean, the menu is well presented; unfortunately, the food is not fantastic, but it's not bad either but nothing to rave about. I am still rating it as excellent because I loved everything else; food improvement will be great!

My flight was delayed by 8 hours I arrived at airport 4hrs earlier but to see if they can reroute me to get my connecting flt to Hong Kong. They auto rebooked my flt. With no chance. Which I missed this entire reservation through kayak. My next flt they got me on was at 6 am. Misses an entire day of my trip abroad all my accommodations seat assignments were missed and missed adding my TSA precheck to my ticket as well as my vegan meal request so I didnt have meals on any of the flight....so not a comfortable experience. Please help me with accommodations upon my return.

The plane was dirty, the seats were torn and broken, the service was the most terrible ever, the bathroom dirty, they will not even serve water you had to request it, the meals were terrible, overall less than Zero, I will never fly Cathay Pacific again.

Despite the crew's rough day, they were all very focused and friendly. The flight was too short for a meal, so no rating on that. Re. the AA app. It still isn't ready for prime time. AA works with Cathy Pacific for international flights to LA and the Aa jump to PHX. But the AA app can't find my trip and this can be problematic with flight delays and regatings at LAX.

Was not able to board flight because boarding pass name did not match passport name and no one caught it.

Had a bad experience with crew member coming back Hong Kong to la the person next to me one of the passenger have taken video and picture of crew member the person that served meal young kid late 20' s 6 5'10 had attitude at his peak anything I asked for I don't know if it was bad day or racial I felt humiliated as people could see difference towards me I no problem with Cathy and my whole family never had one was very disappointed

Everything and everyone were excellent except for the charge for using WiFi; there was no escape from this fee except to not use it.

When getting to our seats a blanket, headphones and pillow where there already. The food was very good and plentiful. I liked when they came around w/hot towels to freshen up with. Slippers, socks and an eye mask was a nice surprise. My husband and I have mobility issues and the transporters were absolutely wonderful and helpful w/the wheelchairs at each stop. Getting from one gate to the next they were a blessing.

The taxi drivers are very rude. Didn’t wait. They said you come in 5minutes or I leave. Did not leave any messages on front desk and they left. We have to hire new cabs in turkey.

Everything was good except for the seating arrangements. We could not get seats to be seated together with my wife. We’re unfortunately.

My first time in business class The in flt staff was outstanding in every aspect of service, the food was amazing, the business seat space made the 11 hour journey easy peazy

It was good, but always can be better. The airplane was old.

I always travel on Turkish Airlines but seriously I am I am considering to change because this is not the first time that the flight attendant are rude and they dont help. I asked for cold water with ice 5 times and I got water with no ice and this is not the first time to ask for something and you dont get it. Also I noticed this behavior only towards people who are not turkish.

There were not enough extra leg room options to purchase. Also the seat Infront of mine was broken and the gentleman literally laid back into my lap for the whole trip. This was the most uncomfortable trip I have ever been on

A lot of things can be done to improve in flight experience

Average at every level . Poor entertainment selection. Boarding was very poor and disorganized. Flight was late by one hour .

Spent over $20k on for business class tickets from DFW. They used a very old Boeing 777 with old Business class cabin which was unclean and stained seats. On a route they normally operate the modern Boeing 787. The cabin heat was set to hot for 11 hours. On the IST LHE route the business class experience got even worse. They operate an even older Airbus A330 where trip was falling apart, seat recline did not operate and the whole experience left us hugely disappointed. Next time we likely will shift to better quality product which stands up to their hype. Turkish need to relook at their fleet plans and not use their worst assets of perceived week markets such as Pakistan.

We flew with Qatar Airlines before (2021) , the service was much better than this time, the flight attendants were not very friendly and cheerful . One of the attendants asked the person setting next to me (by the window) are you Mr. ……, if you may need any thing to let her know . I asked for a dinner meal with beef , she said, we are out, only chicken is available, then she said wait I may get you one with beef, she came back and gave me chicken. Then she gave the gentleman next to me the beef meal . The bathrooms were left dirty and full of overfilled paper tissues, urine every where on the floor and on the toilet seat . Qatar Airways has an excellent reputation and deserves better . Thank you 🙏

Horrible horrible plane for such a long flight. I thought Qatar was a reputable airline. Was proven so wrong. Never again…:-(

Qatar Airways has consistently set a standard in my mind that very few airlines manage to sustain, and once again, this journey in Economy Class lived up to that expectation. As an avid globetrotter who travels extensively for work, I experience many airlines, service cultures, and levels of hospitality. Yet there is something reassuringly consistent about Qatar Airways. It is not simply the onboard service, but the entire experience: the professionalism, courtesy, warmth, attentiveness, and genuine sense of hospitality. The cabin crew are exceptionally well trained, composed, aligned, and polished in their delivery, yet their interactions rarely feel mechanical. They remain remarkably courteous while retaining a genuine human warmth and an apparent eagerness to assist. On almost every Qatar journey, there are individual crew members who somehow manage to stand out and make the experience even more memorable. What I value most is the consistency. Qatar Airways has established a certain benchmark of expectation for me and, over many journeys, has never underdelivered against it. There is a sense of confidence and ease that comes with boarding a Qatar flight because I know the overall experience will be thoughtfully delivered. For someone who spends a considerable amount of time travelling, that peace of mind matters enormously. Qatar Airways remains one of the airlines I genuinely enjoy flying, not because of any single aspect of the service, but because of the complete package and the remarkable consistency with which it is delivered. The only disappointment on this occasion was that my luggage did not arrive with me at my final destination in Kolkata (CCU), following my journey from Seattle (SEA) via Doha (DOH). Unfortunately, the baggage was delayed in Doha. A baggage exception report is already on file with the local airport team in CCU. Given the confidence Qatar Airways has built with me over the years, I remain optimistic that they will once again live up to that expectation, work their magic, and reunite me with my luggage within the next 24 hours. Looking forward to a swift resolution and, notwithstanding this final hiccup, another thoroughly enjoyable Qatar Airways journey.

Mediocre movies Too cold Didn’t have extra blankets Check in was too long (60-70 min coming 3 hours early) Breakfast was terrible Great WiFi however And smooth ride Dinner was decent

Really good food and service. Qatar Airways is again and again provided an exceptional experience.

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.

Didn't have internet connection, and the flight was over booked.
