Good flight. Fiod was ready a bit late hence a hurry to finish before landing. Excellent crew and service

Good flight. Fiod was ready a bit late hence a hurry to finish before landing. Excellent crew and service

Good flight. The food was served a bit late, hence a hurry to finish before landing. Excellent crew and service

Great to have actual hot tastey meal on a flight. Well done

All in all the flight was good. Love the fact that for airline food it was piping hot

I commend the flight attendants on our SFO-SIN flight who went above and beyond to provide us with extra snacks and food. This type of service makes the flight experience personal and awesome.

Seating cramped; close to toilet, foul smelling and noisy, very unhygienic and disease risk Free and paid Wi-Fi NOT accessible at all - misleading advertising Very expensive sunglasses disappeared from back seat pouch. Coffee disgusting and cold

It seems paying premium economy does not make difference with economy. No priority boarding, not worthy paying extra$$$ for premium economy.

Wonderful service, planes and interior in great condition, very pleasant experience

The premium economy seats were not that great. It could have been more premium than economy seats.

People were so nice! Economy seats were small and cramped feeling for me. I’m slender and 6 feet tall

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 .

No red vine, no whiskey, no vodka. No that I wanted all of them at once but still...

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."

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...

The flight crew was exceptionally good. Personal needs were well met. The food choices were very nice.

Excellent. Planes are a little older and could get some refurbishment, but besides that everything was excellent.

Crew experience was more transnational, seats were so close together (LtoR and FtoB) that it was difficult to enjoy much of anything. When the person in front leaned back, there is no space for me. Sadly it was a flight to be endured not experienced.

While I was in great pain, the seat was sufficiently comfortable to allow me to rest and not be in so much pain.

Seats were very comfortable. Crew were excellent. Food very good.

One of the worst flight in business class by qatar airways and I’m no stranger with qatar airways businesses class, I travelled with the extensively in the past 12 years

The aircraft was slightly newer but the food was very bad. Bland and uninteresting. Nothing special at all.

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.

The plane had a technical problem it would delayed 10 hours but they just gave limited information and put all passengers into the Miracle lounge. Ther were not enough chairs and so on.

Ensure there is a choice of food for all customers and also enough food

An excellent airline; polite and courteous cabin crew, excellent meal and drink service. Highly recommended.

We boarded the plane at 1:20 pm It was hot. There was no air-conditioning It was stifling They kept us on the plane sitting there for 1 hour and 10 minutes

No space in between the seats as per them the average height of human is 5’3” and weight as 55, so seats are designed as per the same. Also, the aircraft was dirty and full of insects

when we arrived at Taipei no one help us to get boarding pass. we saw a few people there asked them for help but they just ignored us. There was a guy told us to call Starlux number to get help but we don’t know how to dial the number until there was a lady working there helped us to call Starlux customer then someone came down took us to another counter for boarding pass. Very confused and inconvenient. We might not choose Starlux again in the future.

There was no entertainment and food option limited But the service was first class on an economy flight

They didn't have a vegetarian food in spite of the ore order

Technical problems checking in. Had to wait a long time while they got things ready.

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.

chaos boarding. Crew in business class seemed short staffed and lacking in attention to details initially, but did improve during flight.

Delayed, not enough information. Had to ask for refreshments, crew could have been more proactive

The best so far coz this time it was all male steward on the economy cluster. They were polite, efficient & genuinely courteous. They do not judge you when you ask for more food & peanuts.

Delayed for 45 minutes. Don't know what's the issue. Other than that, food was not to my satisfaction. However it's okay.

My first course flight (Aor-Kul) was cancelled in the morning, and they asked me to board the night flight hence I need to transit overnight for the 2nd flight (Kul-Myy) that supposed to be on the same day. The overnight stay was not provided, (I'm traveling with my spouse, a daughter (5 y.o.) and an infant (2 months old). Hence I booked Sama Sama Hotel at my own expense (fortunately using my enrich miles points). Other than this issue, all services is good.

My experience with the flight was okay. My experience checking in was absolutely terrible. I was told I needed to change my e-ticket number to check in because I missed my flight in PDX. Even when shown the itinerary, they didn't budge and sent me to KLM across the airport. KLM wasn't open until 8pm and my flight was at 7:30pm. Nobody made accommodations in any way to get me to KUL. To add insult to injury, they rescheduled my flight to the very next day, creating a very long layover and did not offer any hotel stay. After this, even worse, I found out later they delayed the first 7:30pm flight to 9:10pm. Meaning, I could have still boarded but they refused to even try to get me on the plane. As a result, I missed a day of work and lost pay for the day. Also, when I went to get my luggage, it wasn't there. It was STILL in Singapore. They had from 5:30pm to 5am to get my luggage onto the plane and they still couldn't get that right. This is the worst experience I've had flying anywhere in the past decade I've been travelling.

Orange juice change to mineral water . Should keep the orange juice.

Entertainment system was too old, crew were unorganised during boarding

No recognition for one World Emerald member. Business class seat has flat bed

No recognition for one World Emerald member. I got row 1 in business class and it was pathetic. No leg space, cramped space, less recline
