Business class check-in was flawless; was automatically given a lounge voucher. Flight attendants were helpful and professional. There was a purser who introduced herself at the beginning of the flight but then I never saw her again.

Business class check-in was flawless; was automatically given a lounge voucher. Flight attendants were helpful and professional. There was a purser who introduced herself at the beginning of the flight but then I never saw her again.

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.

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

First Flight got delayed had to get rebook for another plane ride to connect the next day the process was not helpful at all had to figure the whole processs myself poor service plane was small and customer service was horrible will not fly this airline again

Excellent overall. Boarding was a mess. Queue up too early, takes too long for them to start boarding but they want everyone to queue up and wait and wait.

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.

It was crowded… the bathrooms dirty and smelly. The seats have been made even smaller.

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.

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

Ordered Vegan meal - it was ok, but not exceptional. Seat ok row 39 middle section aisle. Nearly full flight - crew was busy but they did the best they could. There was a USB A port at the seat. I listened to my own music and only looked at flight information. One nice thing was the connection information was made available in the screen.

One of the worst check in process at the DIA as well as the boarding counter Changed seat at the last minute and assigned middle seat while I paid for window seat. Requested many times but to no avail . horrible customer service and very poor process Requesting refund for seat that was changed last minute

Pretty standard for long haul international flying. Food was fine, tv/movie selection was great, wifi did not work at all, crew was pleasant enough.

The flight went great. Of course sleeping is always a challenge for me when sitting up but there’s nothing they could’ve done about that. All went as great as it could’ve. Food great, friendly flight attendants and good entertainment.

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.

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

I did not have WiFi on the flight in business class. This was a problem on a long 15 hour flight. I had important work to do and was unable to do it. This resulted in loss of productivity .

Very comfortable flight. I appreciate the announcements were also in English.

Flight was cancelled by air India. There was no explanation provided why the flight was cancelled. Found out that the flight was cancelled because the Iran air space was closed. Meanwhile, all other flights passing through that region were operating without issues. When asked to refund money for the tickets, being told that “ As checked, we wish to share that Flight AI 116 on 15 January 2026 from New York to Mumbai was cancelled due to Iran airspace closure, which were beyond the airline’s control. While such events can disrupt travel plans, we appreciate your understanding and patience. Our team remains committed to ensuring the safety and comfort of all passengers and takes all necessary measures to minimize any issues. However, we must inform you that compensation is not applicable under these extraordinary circumstances, in accordance with the relevant regulations.” Completed unacceptable and unprofessional behavior!

Needs lots of improvement starting from crew/staff attitude, cleanliness, better quality food & in flight amenities.

Food was below par Quality and None of the Entertainment systems were Working ..and we were unable to turn it off.. Due to the glare we couldn't even sleep for the entire duration of the flight ..

Horrible flight. No entertainment or WiFi for a 14-hour flight. No explanations either. I’ll never fly Air India again.

Several seats in business class were broken. Some would not recline, others had other problems. They need to really update the seats and AV.

Never can get flight and nof light for three days .finally travel by bus. Very bad experience.

Food not of any international or even Indian standard. We have many cuisine available but only paneer & sundry items. Improve & provide some good indian items. Entertainment website or channel out of order.

Flight got delayed by 3 hours but no compensation or anything
