Airline reviews

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.

1. I got very poor check in experience with the counter lady . This is the first airline I ever experienced that no combine check in weight allow . Even we have 4 of us but weight counter by piece . So we wasted lot of time argue and repack . This is super crazy 2. Next I left my Samsung tablet on the plane . And I started to escalate and finally spoke to southern airline lost and found in Malaysia and the amazing answer she give is : system nothing found and please try to call southern airline in china 🧐 . I have been flying many other airlines but this is my first encounterment with such irresponsible airline response and no empathy given to customer . My feeling is nobody bother whether how customer like me feel and I’m just too small for the management to take note .

During flight, some passengers perform stomping leg exercises which disturb the comfort (I.e. sleep) of other passengers.

No good but was short flight. Both of our China Southern flights were on time. No surprises.

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.

The food was perfect. The boarding process is a bit long. Given the late boarding time, I felt very tired by the time I was seated.

Quality flight from start to finish. Customer service is evidently very important to this company. The staff really exceeded expectations.

Traveling with the Chinese airlines , their service superior to the US Airlines , they are much more friendly and the seats are comfortable , In the past I flew with United , now ,United Airline will become history for me .

Pros: "Yes, seats were very comfortable and crew members were extremely helpful"
Cons: "Everything was excellent."

Very comfortable Prem economy seats for a long haul flight. Had a problem with the tv that the crew fixed so was great!

Cathay Pacific seems to be an airline in trouble and on its way out. Lots of broken or poorly functioning things like entertainment screens, seats, and enough well trained staff to handle a full flight. Sad...

Not good. Flight was purchased for my father who needed medical assistance to board and transfer due to a heart condition. No one at Hong Kong from Cathay was there to assist and he barely made the connection. When I talked to him he could barely breath and was not sure he was going to make it. Really poor service even though the ticket stated he needed a wheelchair assistance.

we were upgraded which was a blessing and tender mercy for us. I fell the day before and was in extreme pain from knee to shoulder. Sitting in a more comfortable seat during the flight was an unexpected blessing and experience.

Very comfortable flights. Not so many new releases in terms of films.

Lounge in pukhet not good Very nice new aircraft Super crew as nearly always with Cathay

I felt thirsty and asked the flight attendent for water, but no one came for more than half an hour.

The crew were fine. I didn’t enjoy the food at all. I found it unappetising and really had trouble eating it. The comfort level was fine and our return flight is with Cathay Pacific but honestly I probably wouldn’t fly Cathay Pacific again.

Everything went smooth. All flights were on time No changing gates, . No changing flights . It was like a completely different airlines tha n the last time I used Cathay Pacific . The last flight, 2 months ago, I had before this one was from Philippines also . I got changed in Manila and was told it only added 2 hours onto my flight . My 20 hour return trip ended up being 30 hours return with a 10.0 hour layover in New York with no seats anywhere . Everyone was sleeping or sitting on the floor . Unlike the hotel I was given in Manila to wait for this flight home . I never thought I would use Cathay Pacific again . But I did and this time you were great! I should have complained about the flight and layover from Hell a couple months ago. Consider that I am complaining about that august/23 flight now . Thank you got the great flying experience on my way home from philippines .

Flight was delayed. Drink was only offered during meal. Would have been nicer if crew walk around to offer drink after take off or in between meals.

On the flight back the seats where very uncomfortable, they where so bad that my back started to hurt after the first 2 hours. I can sit in a wooden chair for 2 hours. But these where just horrible, it just shows how cheap the airline has become. And the cabin was heated all those people in a heated cabin during a night flight. It was clear the climate control was not working. To top that off you are not even offered a glass of water, these people are animals.

We purchased a Go First Pass for 10 Euros each so we could board first, but everyone was able to board at the same time so we wasted 20 Euros. The flight left ab out 15 minutes late and was not allowed to land at Healthrow so we had to circle Heathrow for about 45 minutes. This caused us to almost miss our flight from Heathrow to Atlanta.

Severely delayed with no notice. Could have arrived at the airport hours later had we been informed of the delay

Once the boarding sign went on and all passengers gathered in line, we were left waiting standing up for almost an hour because there was a delay.

It would be nice to have vegan options for meals. The entertainment was not working on the the way to Austria. It was only available near the end of flight to Canada. The service was excellent.

Flight was delayed by approx 1 hour. The boarding process and the flight itself were very good, slightly tight squeeze for my legs but overall happy.

The business class layout on this plane is tightly packed and atrocious with no sense of privacy.

Flight was meant to leave at 8:30pm but there was a 2 hour delay 😞

Airmalta does not include meals in their flights and neither offers entertainment.

Pros: "The crew was amazing and took measures to make the flight Covid safe"
Cons: "The food was not the best and Twistees weren't available. Also the seats felt narrow"

The flight was delayed for almost 5 hours, but I understand that it was not up to the company, however how they could handle the situation better, they never apologized for that delay, moreover despite passengers being there for 7 hours only thing they did was to give a bowl of instant noodles, afterwards on the plane tiny snacks, people were there starting from lunch time and we’ve arrived to destination at almost midnight

Flight was delayed for 2 hours for no reason, then we spent almost an hour after boarding because of the weather conditions. If we left on time we could avoid that 😾

Pros: "The price"
Cons: "Staff was not helpful and kind of rude unless you spoke their language. Food options were terrible and not very comfortable seat for 13+ hr flight."
Pros: "The food was good. It was nice that they supply wet hot towels before each meal. The seat was comfortable with the price I paid for. The rest room is nice and clean and quite spacious. The L’occitane toiletery bag was nice."
Cons: "It would be nice to supply mouthwash in the rest room. It would be nice to have a foot step at the bottom to open the trash container. The comforter is not washed and smells."
Cons: "Even for business class there is no TV screen on each seat. Just one small TV screen on the ceiling for a few rows to share. It would be much better with TV screen on each seat. I was sitting in the first row business class and the air hostess skipped me and didn’t give me a slipper. She gave me a used slipper at the end only without a packet. This is unprofessional to treat a business class passenger"
Cons: "Seats are narrow, leg room limited, and food is minimal."
Pros: "The crew was okay. The seating was great on all except for one leg."
Cons: "On one leg, it must have been an older plane, because the business class seats barely reclined."
Cons: "More TV show choices and more Hollywood movies although I understand it's a Chinese airline not American."
Pros: "Crew was great and was happy to get gluten free food i could eat"
Cons: "Not lose my bags :("
Pros: "Beautiful new plane, professional crew, totally decent food."
Cons: "Economy for 13 hours is always a bit rough, but no more so on Air China than any other airline. And the price was so much lower."

Boarding good. Seats uncomfortable when lie flat. Food was awful. Tasted stale and chicken was dry. No live tv or flight map. Had to pay for internet.

Poor technical details on this plane. 1) There was no WiFi on an 8 hour long-haul flight. So no work could be done. That's below the standard expected for airlines these days. 2) The power outlet at my seat was busted and not working. 3) The headphone jack was loose and I had to keep adjusting my headphones to get good reception, or when it slipped out. - The flight was delayed to due mechanics. Sometimes this can't be avoided, I understand, and it's a big inconvenience to arrive that much later when traveling across time zones (then arriving at 4am from the prior time zone). - Also unique to this flight, the northern lights were visible on the right side of the aircraft, but I only found out after we landed (b/c again no wifi). I understand there are considerations about people being out of their seats to look, but I feel extremely disappointed and resentful that I wasn't told so that I could have a chance to look at this probably once-in-a-lifetime cosmic event from a view in the sky. - Flight crew was otherwise friendly and helpful.

I would have preferred something lighter for the second meal. Maybe a small sandwich .

They cancelled our flight the morning of departure at 4:30am.

my original flight was cancelled the previous day, and i was rescheduled onto this flight, which left much earlier in the morning, impacting my previous evening and requiring me to get up much earlier in the morning to get to the airport online. This practice happens way way way too much, and it seems on every airline, though AA is probably the worst.

The crew was very attentive and kept busy serving a variety of treats!

Offered vegetable curry when it was actually tofu which I don’t care for.

The flight was good the crew excellent…but take off delayed three hours!!!

Both mine and my husband's chairs were broken. Also it took 2 hours to get our bags after our flight which was wild.

perhaps eye contact with the cabin crew, instead of abruptness and an impatience to serve.
