Seats not comfortable. We had requested vegan meal and it wasn’t given.

Poor seats. Not helpful crew. The food was awful.overall very very bad experience. Traveled with the family of 5

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

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 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 back of the chair - premium economy could not move back - not worth the price

Never got the wheelchair service when my parents arrived at LA . My mom was 74 , also my dad was 84 years old, both don’t speak English. I double checked with the front desk at Phoenix airport, making sure that they will be taking care of.

We bought the business class tickets. The check-in staff and onboard crew were excellent, providing commendable service throughout. However, it was disappointing to find that China Southern Airlines does not have a lounge at SFO. Instead, passengers were provided with a $35 per person food voucher, which fell short of expectations. Furthermore, the quality of the onboard food left much to be desired, marking a significant decline compared to our previous flight experience in 2019, prior to the pandemic.

Wuhan - Dubai. Old plane: 1. Only USB charger. No power outlet to plug in.. 2. Super narrow seat layout 3. Toilet cover consistently fell down and hit my back when sitting on it.. :( 4. Entertainment system touch screen not sensitive, and need to press hard or use finger tips to hit. Crew were very nice and accommodating though.

The flight was okay it was the kayak customer service that was poor, I have been trying to change my name on my flight ticket 3 days before my flight and nothing got done about it even tho I messaged so many times and phoned, all I got in return was that is was being processed and still to this day nothing has been done about it, I think it’s disgusting and un needed stress to the trip.

Weren’t even given earphones to use the entertainment system

The meals were not the greatest and lacking of appetite but everything else was spot on

Overall, excellent: check-in, boarding, service, and food. The Business Class seating is a little less private and spacious than the world's premier airlines, but still very good for a long haul flight.

On time. Friendly and helpful flight attendants. The plane was clean. Having a wine available would have been nice.

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).

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!

The flight is not bad, but the Business Lounge is not big enough for the quantity of people they accept and there is a limited options for food and beverages.

It was simply bad and on top of that my luggage hasn't been delivered until now. They can't even localize it which is just unacceptable when they are supposed to scan the bar code they put when we check in

On time and no hassle luggage policy (2 checked in and 1 cabin bag)

They lost the baggage and said it was deleted from the system. I had baggage tag so was able to file the complaint but there was no PIR number and update so far

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.

1 hour delay meant missed my connecting flight and 1st day of holiday

Etihad Check In counter/Station manager in Heathrow was bothering and not helpful at all. They are rude and not customer oriented

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

The flight take time was changed 23 times. The system kept sending messages it will be earlier at 4am and eventually the flight was at 9am I didn’t sleep all night because of that

The business class experience is fantastic. The crew were polite but often unavailable even when I tried to call them! I even found myself bringing my used dishes and cutlery up to the crew because no one had come to collect it after over an hour.

Very unfriendly team. It was very difficult to get a cup of coffee. Legroom was extremely small. Old, dilapidated plane.

Very very bad service very tight seats never ever flying with Etihad again

Kuwait Airways is one of the airlines that has entered into competition with other carriers and has become distinguished in the quality of its services. However, it still requires further development, particularly in its digital services related to airport operations and in-flight entertainment. I believe that over the coming years, Kuwait Airways may reach a highly competitive level in terms of the services it provides.

Are you KIDDING RIGHT NOW?!?! SENDING OUT SURVEYS FOR CANCELED FLIGHTS IN A CONFLICT ZONE?!?! ARE YOU FEELING OK??????

Are you KIDDING RIGHT NOW?!? SENDING OUT SURVEYS FOR CANCELED FLIGHTS IN A CONFLICT ZONE?!? ARE YOU FEELING OK???

Food is terrible, service is not good. Staff were not personable and rushed food service.

The onboarding was extremely confusing. Had to climb the stairs to plan from tarmac with carryon bags in hand. No apologies for inconvenience. Overall not quite pleasant experience.

Everything was good and no points to complain. Food is always a tricky concept. Sometimes you like it and sometimes you don’t. Food was redundant from Kuwait City to NY-JFK.

Beautiful Flight took off on time and everything was good

Seats were comfortable. Be aware there is no alcohol on this airline.

Everything was great specially the seats was comfortable even I was in the economy and the food was really Great👍

The crew was attentive and kind. The business class cabin wasn’t very full during the flight so the service was catered to your specific needs.
