Airline reviews

Flight was delayed by baggage loading onto the plane. This was attributed to "inclement weather" (some moderate rain) which could be said to be beyond the airline's control, but the problematic part was that the plane was boarded and doors shut so that passengers sat in a cramped plane with rising temperature (full flight) for an hour. The airline was aware of the status of baggage loading, they could have deferred boarding to keep passengers comfortable.

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.

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

A 16 hour flight from Singapore to Los Angeles had only 2 meals. Please make it 3 meals.

Once again the meal served was delicious - we got chicken rice

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

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.

bad… no veg food was provided eventhough i pre ordered special meal

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~

I was really impressed with the experience it was my first trip overseas. Nice staff

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

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.

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.

same as previous comments. i hate being on a plane that long. no problems w/anything else.

It was very nice. I will try to fly with Qantas whenever I can.

Terrible. 6 hour delay with no explanations and only 15 dollars in food credits. A disaster. I'll just leave it at that.

Much better than I expected for such a long flight.

Flight was cancelled about 1.5 hours before departure. Replacement flight provided scheduled 1 hour later. Late boarding, late departure and arrived Melbourne nearly 2 hours after originally scheduled.

Good - better than other airlines in terms of food and seat comfort.

It’s a very long flight and there are so many people on board. Perhaps a warm washcloth now and then to freshen up

The crew was very helpful to my family, especially when my daughter became sick during the flight. Will fly with them again.

Too many passengers are bringing on too many large items as part of carry on baggage where it should be checked in. This is not the fault of Qantas but the stupid mindset passengers have now about trying to bring anything and everything on as carry on luggage where it should be checked in.

Better than expected, normally I don't use this airline because they are too expensive for me, but if you can afford it, good on you, you won't regret it. Regards.

Flight was fine, food better than anticipated and flight attendants were helpful and friendly.

Our headphone plug is broken, we can not enjoy our entertainment, especially traveling with 5 year old who like to watch movie

Reasonably comfortable. Plenty of room. Crew were attentive and continually informing passengers of position. Although stuck in runway for 1 hour, weather issues, it felt like we were the crews first priority

Need a do not disturb sign if you wish not to have any meals so that they can wake you or have the meals served . Left very sad and hungry .

Pleasant, attentive and efficient flight attendants. Boarding process and seat selection easy. No internet on transatlantic flight. Extremely uncomfortable, rigid seat.

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
