The seats were more narrow than at other lines. Food was mediocre (economy class)

They made 22 hours aboard aircraft very enjoyable. I was very impressed with the attention to detail and level of service. Singapore airline will be my preferred choice going forward.

Service excellent would chose Singapore airlines as my first choice

The staff were amazing and very kind. The seats recline a little too far back and are up close when sitting behind.

We flew business class. It was excellent. For a 6’4” individual, the seats were slightly uncomfortable for sleeping. But this is only comparison to other business class seats. Otherwise, the crew was incredibly attentive, And the service was impeccable.

Fantastic patience when one of the passengers behind me was an absolute horrible, horrible person and the girls just kept smiling and doing their job with patience and kindness. Well, done to the crew.

Excellent- a lot of food Disappointed with the premium economy pouch- did not have toothbrush and tooth paste or socks. Other airlines provide them

On time, friendly staff and decent food. Would definitely recommend.

My daughter and I had a pleasant trip to Singapore. Reliable and on time.

Didn't like much at all Nowhere near enough legroom, narrow seats. Aisles not wide enough for safe food trolley access and husband had his knee hit cos not enough leg room. Would take a lot to convince us to fly Singapore Airlines again which is a pity cos it was always our go-to airline

Not good - chair back could not move back for premium economy. Not worth the price

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

It was okay. Boarding the staff made you feel rushed like we were late or something

It was great. The staff were so nice and helpful the food was great and they always made sure I was okay. As a foreigner I was worried about the language barrier but it was absolutely no issues. I highly recommend

Crew: Everybody was polite. People just need to get efficient and less reworking things. Entertainment: Could have move movies and games. The “music” section is a joke, only ONE available. Food: The food provided on the flights boarding in china needs a serious reworking. Too much oil, bad for your stomach, tastes too artificial and the eggs were a giant mass of green dough.

We were diverted to Chengdu, because of bad weather and finally made it to Chong King about 7 hours later

No wheelchair service at all ( I did request that service and also purchased the priority assistant bundle) , what a waste of money

Never got the wheelchair service when my parents arrived at LA . My mom was 74 , also my dad was 84 years old, both don’t speak English. I double checked with the front desk at Phoenix airport, making sure that they will be taking care of.

Food was terrible. Fish was equal to a sausage and scrumbled eggs were terribly green with a quite weird fllavour. Everybody with me hated all options. The best food was the bread with butter.

We bought an upgrade to Business Class at the airport but did not realise that it was not the regular Business Class. The 787 Dreamliner was very dated with the seats not as comfortable as other airlines and some things were almost coming off. We were then told that because it was an upgrade at the airport, we get to sit in the BC cabin but will be served economy class food. So when everyone else got served in china ware, we were given the tray you got in economy class. The wifi does not work. It only connects to watch movies (which is the same as what you find in the ICE) but the internet does not work. The cabin crew while were friendly, were not responsive. Overall, I will never fly China Southern again.

Cathay has a great reputation, though it's baseline economy seating is nothing to write home about (and SE Asia flight passengers sometime lack 'routine stateside' etiquette). On the other hand, food was great, flight attendants were nice, and price was very good~

Not enough food for everyone. . Always run out of food when we ask

Customer service was exceptional. I heard it wasn’t a great airline, my opinion has changed after flying with them

I was amazed at how clean Cathay Pacific planes were compared to our US domestic airlines. Everything was great all but the food service I was just okay with. Shorter flights with other airlines usually provided more meals and snacks that I have been on. Almost a 16 hour flight just two meals and no snacks with Cathay Pacific. Even ran out of what I wanted for one of them. Other than that top notch!

My sister and I were booked on flight CX844 from Hong Kong to New York, following a layover from Hangzhou. The scheduled layover was already over 7 hours, and the flight to New York was set to depart at 2:00 AM. At 11:00 PM, I was informed that the flight was delayed until 6:45 AM, significantly extending an already lengthy layover. I spoke with a representative to inquire about rescheduling or hotel accommodation, but she rudely insisted that company policy only offered a $150 food voucher, which was unhelpful as I had already eaten and most places were closing. She refused any alternative support or access to the Cathay Pacific lounge to make my wait more bearable. As a loyal Cathay Pacific customer, flying with the airline every year, I was deeply frustrated not only by the delay but by the poor service and unprofessional attitude I encountered. I believe this situation could have been handled with more care and flexibility.

Cathay was not the problem. The problem was the customer service from Kayak/Underprice. Will never book through Kayak again.

Cathay flight was fine, Amsterdam airport was a nightmare, spent way too much time walking to our next connection, no travelators.

As a solo traveller, I always prefer to have an aisle seat, but the flight was so full, there weren’t any available. I understand that the seatbelt sign sometimes has to go on if turbulence is anticipated but after the second food service, it was on continuously for about an hour and a half and there didn’t seem to be any turbulence at all! With seats reclined, my fellow passenger in the aisle seat asleep and the seatbelt sign on I felt very trapped, extremely uncomfortable and in desperate need of the bathroom. The positives were that the staff were very friendly, the entertainment was great and we actually took off on time and arrived in HKG earlier than expected.

Mediocre. Nothing special. Bad airline food Never received the food I requested Slow response from ground staff concerning my wheelchair. I was left at a holding area and had to walk the distance to the gate. In Hong Kong

Was a nice experience, crews were nice and accommodating. My only complain is the super tight leg room for the economy class.

The flight isn’t great, as the plane has faulty with light and noise. It blinks and make noise for 8hrs non stop! Causing health and sensory issues! Causing Hazard matter to all 3 babies that on bassinet seats. This matters affected 12 passengers and the most horrible flight I ever experience. Have been flying with MAS for more 30yrs and this is the worst! Very disappointed

AC not working, just slowly blowing room temperature air. Long taxi time does not help as well. Sweating all over the whole trip.

Did not take as cancelled 3 time so took another airline

It was a 2-hour flight so they didn't have much time for serving food. There was some turbulence so they could not serve hot coffee or tea for the safety reason. Good service, good tasting food, nice plane, a little bit of delay.

The IFE is quite unconvenient if using our own device. Not all passenger brought their own earphone/headphone.

Ok, but legspace on MH0127 from Kul to Per was too small. It was not possible to tilt my seat which I don't understand because the seat in front of my could do it. So I didn't rest on the flight. Also, the crew was probably understaffed because it took very long time to take trash after the meal. Everything very different from the flight with Malaysian Airlines from London to KL.

Service / food has to be much better. Staff were not very attentive to requests. Requested for a second serve of coke and got a weird look back from the host! Was also told they don’t have extra water bottles when I requested for one before sleep! Dinner time food was very minimum and average.

An overnight Doha to KL. Great sleep, good service and tasty food in business class

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

The cabin was quite noisy as there were lots of children travelling for the school holidays. Found the selection of movies limited.

No entertainment and the seats are well worn.! To the point it feels like your sitting in a bowl

The seats of the Boeing 787-10 Dreamliner were ridiculously uncomfortable. I was on 10 flights during this vacation and this plane was super uncomfortable both times I was on one whereas all of the others were perfectly fine. Additionally, these planes do not have any air vents that passengers can control, the climate is entirely controlled by the crew which made for an extremely uncomfortable temperature for the duration. The flight attendants tried to make everyone happy with the temperature but several people you could tell were excessively warm and just wanted a bit of airflow.

Everything was fine except not posting the gate number until 14 minutes before boarding. In an airport the size of Heathrow, that was unacceptable.

We already had a five hour layover in London, and then they cancelled our flight about half hour before we were due to board. They wouldn't give us access to the lounge and hanging around the extremely busy terminal for another three hours until our next flight was crappy. 8 hours in a busy terminal is awful. The least they could have done was give us access to one of their quiet, comfortable lounges for the inconvenience. I heard from others that they do this a lot -- cancel these short flights if they're not completely full. When we got onto the next flight it was absolutely packed and uncomfortable. Just very disappointing. British Airways used to be a great airline to fly with, but it doesn't feel that way at all now.

Don't fly thru London Awful and huge U need 4 hrs to transfer cuz u have to tale buses to and fro from airplanes Bad business

Staff with low service level, forgetful. Temperature at 15 C and after asking twice to raise the temperature the crew did nothing.

They took good care of me on the plane and had it not been for handicap assistance I would definitely had missed my connecting flight . Not BA fault but The airport security instead . Two hours is way too long for security

The least comfortable business class seat I have encountered for a while - very very firm when reclined making sleeping difficult. Cost cutting is visible everywhere - no offer to refill drinks (the wines were not good - so no real issue there :) ) Just not worth what BA charge

old seat need to go! outdated and uncomfortable. I waited 40 minutes for my bag

They had about 20-25 people overbooked. Including me. Why is this?? I was put on a flight to NC an hour later with a 4 hour layover. I was supposed to be home at 1045am instead i was home at 7:30pm. An extra day to pay for dog care.
