Leg room wasn't that great. Other than that it was a good flight

8.0 ExcellentAnonymous, Oct 2025LAX - HKG

Leg room wasn't that great. Other than that it was a good flight

Issues: 1) the charging issue as described in my previous survey 2) when I requested diet coke during the breakfast time, it is not available. Why? I can't drink diet coke in the morning? 3) when I tried to transfer to this flight, its gate information was not available to me?

The lead business class attendant was excellent. Made a point of greeting you and knowing your name by the time you leave.

They downgraded me from premium economy to regular economy and me had 2 major lay over and had to have an emergency landing due to engine failure mid flight Don’t use them worst experience I have ever had still dealing with the trauma

The only problem was my connecting flight to Chiang Mai on Hong Kong express that I booked through Cathay Pacific was canceled and I was never told about it. I was rescheduled on a flight 10 hours later. Very long day at rgr airport in Hing Kong after a 13 hour flight but that's OK, I understand things change but I think I should have been told. I would have prepared myself for a long wait. Great flights all around though. Thank you

Overall pretty good experience. It would be nice to have caught the attendants even they were flying down the aisle with snacks, and if they could cater to multiple dietary restrictions (bland and no lactose. The customer service chat is a bad experience), but otherwise no complaints.

Boarding at the airport was not well managed. Otherwise, had a good flight sitting in the first row (which I paid for). Crew was pretty friendly, and flight was smooth.

I am Vegetarian also has Gluten free food. However they gave me chicken and fish which is gluten free, but i am a vegetrain and i requested crew Hindu meal vegetarian, they said they will come back. .but they never showed up even i asked 2nd time. They could have compensate. I also request airline industry to have another option Gluten Free for Vegetarin people as well. Because Vegetarin people will have gluen issue...

it was a great experience as far as business class.. but I have had better meals and wine on other airlines.. that said.. the price was a great value for what I got in return.. crew made the difference.

Check in process at the kiosk, crew in flight and overall comfort was good. Food selection could have been better. Flight from Hong Kong to Los Angeles did not have any vegetarian main course option, it was either sea food or chicken. Being a vegetarian I could only eat yogurt and fruit. Most international flights have one vegetarian main course dish which I found missing in Cathay Pacific menu.

Awesome hospitality, awesome staff, awesome food & awesome travel time. Thanks

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

The flight was operated by IndiGo and not Qatar, which is a budget airline from India. Nevertheless, the flight was uneventful.

Terrible experience resolving missed connection after flight was delayed. 3 hour queue at transit desk, not enough staff, no organisation, worst ever flying experience.

Seating is terrible, having seats so crammed is unacceptable for a 15-hour journey. I cannot stress enough how uncomfortable it is to sit in such an aircraft. Leg space is roomier in a domestic aircraft. I have not experienced this kind of crammy seating in domestic flights either in the US or other international airlines overseas.

Aircraft was spacious compared to American Airlines, food was great, entertainment was much better with a wide variety of options, and the crew was very polite.

Overall good. Food choice in business class is a concern as same dishes on every flight for months. Crew is great and seats on this sector were fine . They need to have more variety in dining

Very unimpressed that I was dumped from the seat I had booked and paid for after check in. Apparently a family wanted to sit together, however as they all were adults I think they should have pre booked their seats like I did. I will be approaching Qatar for a refund. That and the dreadful state of the flooding toilets made me wonder how they managed to be voted the best airline. Not worth the money.

Was downgraded from business to economy due to a faulty seat in business class. However when I boarded the plane there were no less than 5 free business class seats. Will never fly Qatar Airways again

The overall flight experience between Doha and Kolkata was satisfactory. The staff onboard were notably engaged, responsive, and enthusiastic, providing a level of service that stood out, especially when compared to the less attentive crew on the earlier leg from Heathrow to Doha. Their eagerness to assist made the journey more pleasant. Additionally, the time spent at the Silver Lounge in Doha contributed positively to the experience. The lounge offered a comfortable and relaxing environment, with adequate amenities and attentive staff. Overall, both the flight and the lounge experience in Doha met expectations, making for a smooth and satisfactory travel experience.

Did not provided with option for class upgrade. Staff at gate was not able and willing to accommodate with class upgrade, eather with plenty empty spots in business and first class.

I am a larger than average person and in my opinion i don't think it's fair to allocate a window seat to anyone who is my size or larger, i was seated between 2 large passengers on a full aircraft. The guy in the window seat also occupied a portion of the middle seat (my seat) which made my experience of flying with etihad very cramped and uncomfortable, i was flying from Abu Dhabi to Bangkok. Had this been a airbus 380 it would have been better as the seats are larger but unfortunately it wasn't so i had to endure the 6+hrs unable to get any rest

Old plane, old entertainment system. It wasn't working throughout the entire flight. I was offered to connect to their system via Wifi to watch on my phone. Crew wasn't very helpful except one lady who turned the experience around.

Stewardess was attentive and was actively roamin to check the passengers on the biz class

It was worst flight ever of 26h. Poor service and seating. Flight from Abu Dhabi to Islamabad service and seating was worst ever. No tv extra.

It was OK as the seat which we paid for doesn’t have any window. We paid $120 for 3 seats but it’s for nothing. Crew could not help. None of the ports worked so all our phones went dry

I had a terrible experience checking in at the airport for my flight. I booked my ticket initially through Kayak while it was promoted as a ticket that offers a carry on and 2 suit cases. (I have a screen shot as a proof of it) I selected it to buy three tickets and paid online. Couple of minutes later airfare assist which is the OTA offering the ticket called me saying My card declined. So I used a different card that went through. I was surprised that they increased the price ticket by a $167. They said the ticket no longer exists and because my card declined I had to buy a new one. So I did. The day my family and I were traveling I could not check in and when I went to the airport I was shocked to be told my ticket had no bags allowed and must pay $200 per bag for three people 6 bags mean I have to pay $1200. I called the travel agency as I feel I was scammed the confirmation didn’t say anything about the bags and they never told me the new ticket doesn’t not include any bag so they changed it after I selected it on your app without informing me. Very sneaky. The travel agency said they will reimburse me only for one bag person. Which means I still paid $600 I still feel very disappointed to pay such an expense. I have always used Kayak to buy my flight tickets and telling everyone how good your rates and app are however after this I feel I was mislead and paid more for something I should not have to. You allowing such an agency on your platform will surely hurt your reputation and level of integrity. I have all the proofs from the screen shot to the confirmation email from them, the or email offering to reimburse o e bag per person and the $1200 bag fees receipts that I paid on the desk. I must be refund the full amount and I look forward to your response.

The food could be better. Toilets were smelly all along

Crew Check-In – Kolkata (CCU) The crew handling check-in in Kolkata was outstanding—efficient, courteous, and highly organized. Flight Segment – CCU to Abu Dhabi (AUH) A standard flight overall. Notably, only one in-flight meal option—a vegetarian curry—was available, which seemed unsuitable for a red-eye journey. The crew offered no alternatives, which was unexpected. Flight Segment – Abu Dhabi to Rome (AUH-FCO) Comfort improved on this leg, but service quality was average, falling short of Etihad’s premium standards. Crew attention was heavily absorbed by a difficult couple in Row 15 (port side), resulting in disproportionate focus. It was concerning that a steward had to personally return to apologize, a task better suited for supervisory staff. This highlights a development opportunity for supervisors Anna and Quashim in managing guest escalation professionally.

Horrible. After paying for seats, I was cramped, my daughters legs kept hitting the seat in front, I had no overhead bin space and no help from stewards on board, the food was served cold, when asked for snacks was told to wait and never received any, the flight was cold with no temperature controls. Entertainment was outdated. I booked this through partnership with American Airlines but will avoid in the future.

In my return flight they couldn’t identify my ticket or boarding pass, I had to go to 3 different counters until I was able to get my boarding pass. The food was on, it was the bear minimum. They didn’t even recognise that I was a Muslim and can’t eat meat, chicken or pork. In one of the trays I believe they served me pork. The staff were very pleasant, but they need to be aware of their surroundings more carefully, one of them stuck her lower belly right into my face! I was shocked and very uncomfortable.

Overall I had good experience with China Southern airline. Nothing to claim. I hoped they could improve the meal quality that is.

Wow very impressed by the quality and attentiveness of service of China Southern. Lived the blankets! Will definitely fly with them again. Despite language barriers, a few attendants know enough English to understand our rudimentary Mandarin and respond to basic questions. Although they don’t explain the beverage and meal service on the website or ticketing documents, they offered regular beverage cart and snacks during the beginning hours and end hours of the long, transoceanic flight. A full meal at the beginning and end of the flight as well, and a midflight small sandwich (dinner roll sized) but we weren’t hungry and didn’t try that one. The expectation is that every sleeps during the middle of the flight. We were on a “redeye” departure from LAX with a morning arrival in China, so I don’t know if this service pattern is the same for other flights. The domestic flight we took from Guangzhou to Harbin offered conventional refreshments and meals like a US flight service. Note that they didn’t offer diet sodas. If you like to stay hydrated, I recommend bringing plenty of your own. It is served in small cups like any other drink. You can ask for a bottle but they’re tiny - about 6 ounces.

China Southern was not the problem. I booked my flight through Kayak and also received a booking reference and alert details regarding departure time and gate numbers… however Kayak NEVER actually booked my flight! We were stranded at the airport without a flight for a long awaited holiday!

The connection between LA and Atlanta was too much stress

Terrible boarding experience,,food is very poor that I I . Never going book this airline again.

The crew were kind, patient and responsive. The service was excellent, even though we travelled the cheapest economy class. We arrived at our destination 40 min early, which for a 15+ hour flight is a great bonus. The boarding seemed a bit "loose", but got us boarded on time, and the plane was off exactly @ 0:30 hrs.

The airport didn‘t give me the ticket. I called customer service to ask for a refund but they kept giving me a perfunctory response and refused to refund me.

The flight was delayed hours and most flights from CS are always delayed. Plane was efficient and got us home but not the best food and no entertainment system at all.

Not good - chair back could not move back for premium economy. Not worth the price

cannot get seat information for LAX to IAH when check in in XI,AN

UA is ok. But check in was a very bad experience

I hate that you cannot check in online and when you are at the airport, there aren't any aisle seats left. Also, they could work a little on subtitles for their movies (not everyone is a native English speaker).

Nothing to complain of, the only reason I am not giving better marks is that I am used to flying with ANA and they are the top.

It's terrible that we can't do online check in because we didn't buy the tickets directly from Air china. It was not explained until I contacted Chatdeal and we could not sit together.

Communication between the captain/crew and the passengers needs to be improved.

Food and service are good. Bathroom was lack of lotions and cleaning. That should be improved.

Food & service very good next I will pick up again

Chinese flight attendants didn't speak english well. They didn't care enough to remember that I (east asian who isn't Chinese) wasn't Chinese and spoke English. Announcement in english on board was poor and I find it very difficult to understand what was announced. Also, a cabin bag allows only 5kg!

Everything was not satisfactory - the flight was delayed, staffs were ok but they didn't speak English well. I am from east Asia (not Chinese) and they didn't care enough to remember that I wasn't Chinese but persistently spoke chinese to me. The flight announcement in english wasn't clear to understand.
