one hour transit not good. cathay pacific is not helpful at all

Trip was fine. My only complaint was that when the passenger in front of me reclined her seat (which was, in essence, the whole flight except landing and take-off,) it was uncomfortably claustrophobic for me and very difficult for my husband to get in and out of his window seat. Also uncomfortable to watch the entertainment because the screen was right in your face.

The flight was just ok, but the vendor made it exceptio ally bard to manage my own reservation and would not give me access. The blocked all of the one time pins to come to their email address which caused me.to go through them eceryrime to get seats see rhe reservation and even get wheelchair access for my sick 71 year old uncle. They only xommunicates via a bot which gave me incorrect info. I thought this was Kayak and not underprivileged. They ruined his trip, did not get him aisle seats and made it impossible to purchase extra leg room. It was a horrible experience. He was taken to hospital on arrival only to find he had blood clots and pnemonia while trying to navigate the airport. This vendor is very irresponsible and the airline could not access his info.

It was good. The planes needed to be updated though, they were dated and the entertainment systems were old. Service was amazing. The pre-booked meals were lacklustre.

Overall, not good. Super late boarding in Hong Kong because some last minute issue with a plane. The boarding process is chaotic. Kathy Pacific should seek to do better with punctual departure time. Caused a lot of trouble with missed connecting flight.

The morning in Hong Kong was ridiculous. Very chaotic. The flight was delayed. Missed connecting flights. Kathy should be more competent in getting the planes ready ahead of time so that flights can depart on time.. totally ridiculous and unnecessary. Very poor performance.

Flew from lax economy on cathay 777. Seat configuration 3-4-3. When the forward seat reclines it feels like someone is leaning forward and staring you. If you are slightly big tray tables will touch your abdomen even with seats upright. AVOID this above 777 configuration at all cost for a long flight. However their Airbus 350 3-3-3 configuration felt spacious and Seats wider.

Crew on this flight dedicate their business class service to their high priority members. They would get priority service even the seats are behind me, and meals priority service and orders. I get the left over choices. I refused to eat because I felt discriminated, never booking this airline.

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?

Close to excellent. The only problem is when I try to charge my phone on the USB in front of my seat, the battery level is decreasing rather than increasing. Why?

Food and welcome services were good , however we experienced issues with the entertainment system and poor headsets

Very good flight and very kind crew Only thing is I wish there would be a vegetarian option for the meals

Lovely staff, comfortable seats. Transit time was short but they had great processes in place to get us on the plane.

For a domestic flight, seats are ok, but fir us as tall dutchies, the legroom is too small. However, for a short and affordable flight, is not a big problem. Staff is still very nice and a complementary water very welcome.

2 hours delay, time changes started already 2 days before the flight

Average, not more then that. Cannot compete with Singapore Airlines

I bought the front row seat and made and early online check in but they changed my seat to the back row without prior notice. The inflight meal was too poor, only a piece of small finger food. The boarding is a disaster, everyone is stuffed in a bus in chaos. Doesnt worth the money at all.

Poor. Flight was delay without prior notice. Poor boarding. Poor meal service. Plane was dirty and smelly. Does not worth the money.

Overall very nice airline. The seats were cloth unlike leather seats I am accustom to on planes. The food was adequate. I had to use a paper boarding pass as they do not like electronic boarding passes. I scanned my electronic pass, but the gate agent requested the paper pass. Luckily I had a paper pass, although my electronic pass worked and when the paper pass was scanned it stated I was already on board.

I am a bit upset with the check in counter, I signed up a wheelchair for my mom so they wouldn’t grant us her boarding pass. We got to the airport a couple of hours earlier and they had us wait and no one ever gave us her boarding pass or the wheelchair, I had to go back and complain when it was already time for our flight to board. Since we got their earlier, I could have easily pushed my mom myself and we could have relaxed and went to the lounge while waiting… when I finally got someone to help us he couldn’t explain how and why they dismissed us in the first place.

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

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

It never happened. Me flight from Doha to São Paulo was lated and the time of waiting for the luggage arrives when we arrived in São Paulo was about 1 hour and half. So it took a lot of time just waiting the luggage of flight that was already late, consequently we lost the flight to Recife with Latam Airlines and had to go to the Qatar office to arrange another flight to us to Recife, that one with Azul Airlines. It was more 4 hours waiting to this other flight to knows that this other flight was delayed too, total of 5 hours more at the airport to waiting to go home :/

I wish the leg room was better for Economy especially for the outbound flights to India . The outbound flight to US and Qatar was good

The check-in and crew staff were wonderful. The food was reasonable. The online side Qatar was very poor. Seats were very tight and not very comfortable for a 14 hour flight!

I was travelling 3.5 years after. Agree Economy is no business class but the food was mediocre. Ordered a Hindu meal, the salads were bitter . The food was really below quality and had no tast from what I had in the past. Indian Railways probably have a better quality food when compared. However the kids meal was really nice and really appreciate how they were taken care of. The restrooms were dirty .

Overall the experience was neat with crew being nice and caring especially to parent with kids. The free snacks option was okay. The kiosk at Philly airport didn’t work.

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

The staff was the best I have experienced as a frequent traveller in a long time.

I had to stay in the airport 15 even with a hotel reservation..i was refused to inter to qatar cuz the hotel was outside the airport. They could have offered a solution. It was really exhausting for me and my family.

Do not overbook flights and kick out confirmed ticketed passengers :-(
