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

did not get a notification about seat selection ahead of time. We didn't end up sitting together.

I was denied boarding at the Brisbane airport and it seems like I won’t get any refunds from the airline

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.

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.

I paid extra for seating when first booking flight to be in a comfortable economy seat They still changed it to a middle seat regardless. When I asked for it to be changed back to aisle, they could only give me one at the back of the plane in the least comfortable seats.

First off, it wasn't clear that my first flight was to be operated by IndiGO. While the flight itself was fine, this meant that my whole initial check in where I would've properly verified my seating on my Qatar flight/requested an upgrade was impeded by the fact that I had to check in with IndiGO. They said I would separately have to go to Qatar counter to deal with second flight leg issues, which was impossible given how long the check in took/no time available to do so.

All great, because I was given a seat with extra legroom on this part of my trip.

Very efficient and professional staff. Food was good and so was entertainment selection.

As good as you can expect an economy flight from Europe to Australia to be. Nothing agains Qatar, just feels like every new generation of plane gets tighter.

Paid $10 for wifi for full flight duration and the wifi wasn’t available after initial 2 hours

Boarding from DOH to SYD the Business Class were pointed in a separate gate but no one there to receive us. Otherwise it was ok.

My flight was delayed. I was rebooked twice and even the second flight that was additional connection in London was delayed too, so I ended up spending more than 24 hours flying between four different countries and to be honest I’m not sure whether I ever want to use this airline again. My luggage is still delete. It’s been more than 48 hours now so to be honest, I’m not even sure how to describe the level of frustration I have.

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.

I payed for extra leg room but in last moment my seating place was changed and i got standard one seat. Staff was not able to do anything , so was very disappointed because of this.

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

The seats seemed smaller than other business class offerings. The entertainment menu was limited. Flight crew was good.

Business class ticket should include lounge access and seat selection. The food quality and varieties should be more. It was surpirise that no dessert was offered.

Ethiad wanted to charge me $1100 for 2 checked bags on a ticket that was $550. Nother the airline or airfare assist was willing to help before arriving at the airport. All parties said it was the other responsibility to help. Never flying ethiad or using kayak again.

Dirty and smelly lavatory and toilets in Wamos Air operated flights

It was great! Kept the time. Provided what was promised

The flight was over 1 hour late taking off ,when I arrived in Abu Dhabi ,I missed my connecting flight to Bangkok so I had to wait almost 6 hours for my flight arriving in Bangkok at 6:30 am ,So I missed a whole day of my vacation and my hotel room sat empty so I paid for hotel days that I was not there. In Abu Dhabi there was a woman that worked the desk at transfers that was so professional, courteous , helpful,and may I say absolutely beautiful .she got me food vouchers for my layover and was a very calming presence. Besides that I will never use Etihad again I will pay the Xtra money . I'm sure they won't read or see this but it's my "2 cents" I'll use an airline that respects me and my hard earned dollars

Very friendly and attentive flight attendants, good food service. Seat was comfortable. However, the in flight electronics were poor. The screen froze repeatedly; the controller died; the headphones are a hit or miss; the wifi wasn't usable. Very scarce communication before the flight (no email reminder). Almost impossible to understand in-flight communications (audio was very poor).

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.

Your staff was exceptional. Could teach the other airlines-rules on etiquette, and service. Excellent landings on flights, carried out by your pilots. Only complaint is long delay on return flight in Beijing, onto Vancouver.

Worst than I expected, crew was not attentive, meal was as disgusting , they didn’t even drink selections as they would to other passengers. I felt discriminated

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.

I do not have any issue after travelling but not able to return back to Newyork because my flight is cancelled. Requested to refund my full amount.

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.

Boarding /lounge :Chaotic boarding , business /first class had a dedicated line but it was upto to the passenger to figure out and use those lines .Oasis lounge is clean but tiny so it felt over crowded . Neither the food nor amenities felt business/first class . Cabin and tech : 2-2-2 configuration needs to go . Leg space is cramped , headsets didn’t work . WIFI does exist or didn’t work on the entire 20 hour journey . Food and crew : Preordered “Hindu Non vegetarian” meal , crew was clueless , they didn’t even bother to ask if they weren’t sure what that meant . Served mediocre vegetarian food though menu had chicken /lamb options . In short , worst business class experience of all the airlines I flew to date . Not sure if there is one area they compete in let alone excel … avoid if you can .

Food was not available in the middle of the trip that is 13 hours

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

Next time im going to use Kuwait air lines, hopefully
