Boarding and deviating was mediocre. At boarding they have not prioritized Business class. During debarking they prioritized premium economy. Also bus rides both times.

Boarding and deviating was mediocre. At boarding they have not prioritized Business class. During debarking they prioritized premium economy. Also bus rides both times.

I thought I already provided this feedback. 12 hours with no wifi is unacceptable. Lay flat is nice but a bit cramped.

It was ok, it felt more like an internal flight than an international flight so I guess expected a slightly better standard. Nothing really wrong with it but there was no inflight entertainment. Food and service was good.

The flight boarded and departed pretty much on time as it’s just a one hour flight there is no food or entertainment so I marked that at the neutral but they do offer water and I’m sure if you needed some food you could bring your own onboard. This was our third internal flight with Vietnam Airways and I recommend them.

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

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.

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.

I had sometimes my trips with Vietnam Airlines and I like it 😊

Vietnam airlines is just one step upper to the cheapest one (vietjet, if you wanted delays and cancel or feel like a criminal then vietjet is for you) for sure better customer cares and on time.

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.

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.

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.

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

I love flying Chinese airlines in general but China Southern is probably the worst of the lot. The service is poor and food is below par.

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.

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 .

Flying from Koh Samui to Ha Noi with a layover in Bangkok. Vietjet cancelled flight. When I went to the counter they told me to call from r information. I asked for the number and they said they couldn’t give it to me. Be a little taken back I asked him to repeat that while I was recording on my iPhone. He told me that was unacceptable and called the airport police. I deleted the video but had to deal with a big hassle. Then booked with a different airline. Vietjet wouldn’t refund the ticket. Luckily Chase Sapphire didn’t have a problem with refunding me. Vietjet blows!

Terrible customer service. My last choice to fly now if there is no other options.

First time flying with VietJet Air is so so. Check-in process for domestic is okay and easy but during our flight back to Manila, the ground staff at Tan Son Nhat International Airport weighed our hand luggage before boarding when in fact, it should be weighed during the check-in process. They are very strict in terms of the 7kg hand carry it’s either you’ll pay extra, or leave things behind.

Late departure, late arrival, and personal items on laps during takeoff and landing. Departure gate opened on time, but no direction as to whether to board at front or rear of plane based on seat number. Fashionable staff with sunglasses inside the plane and cockpit remained for ten minutes after the boarding complete announcement. For a scheduled 80 minute flight, adjusted to 65 minute as noted on takeoff; the total time on the plane with delays was r more than two hours. No confidence had there been an emergency that anyone would have been able or aware of what to do.

Our flight was delayed for about 3hours however the ground crew made it sure that we will not miss our connecting flight from Hanoi to incheon.

Seat pitch is narrow moreover the agent assigned seat in front of emergency exit window which is not reclined. A terrible 4hr 40min flight from HAN to DPS

1-Airlines did not send any info to inform the clients about changing fight number. 2-Delayed too long on runay without any explanation

Not punctual in departure and seats are very tight and narrow. Crew should handle noisy families during flight.

Paid for seats near the window but given seats right at the back, near the toilets. This location was so noisy with the blasts from the aircraft engines blowing beside. Not a nice one 😞.

Very bad experience and will never try their service again. Not even water serve for 8hr flight. Will have to wait for every prepurched to cimplete before can buy water.
