Flight attendants were awesome! Very helpful and patients. Some food were good but maybe not serving fish that kinda make the whole aircraft smell fishy. The “fried pork” was tasty but too much skin so it doesnt taste that great.

Flight attendants were awesome! Very helpful and patients. Some food were good but maybe not serving fish that kinda make the whole aircraft smell fishy. The “fried pork” was tasty but too much skin so it doesnt taste that great.

Clean modern comfortable. Food could have been better, I only ate breakfast I wish they wouldn’t wake sleeping passengers who would rather sleep through dinner. No tea or coffee for breakfast

Really great service throughout and the food was really nice. I can highly recommend thank you very much.

Fast and efficient flight. Wifi worked well. Food selection could have been better

A little more room from the reclining seat in the front of me.

It was fine. Nothing special but nothing went wrong so all good.

Overall the airline tried to give excellent service. The wheelchair service was bad at SFO. My baggage was also delayed but I thank them for taking the trouble to find it and deliver it to my home.

They ran out of the second choice of food was stuck with fish

I felt that the whole experience went very smoothly. The aircraft was extremely clean and tidy on boarding. The cabin crew were beautifully turned out very, very efficient and were a credit to Singapore Airlines who are now my favourite carrier.

Excellent crew service. Professional, courteous. Service with a smile. Good food Very decent flight experience

The quality of food is going down comparing with old history of excellent food. It was cold and a bad quality. The crew is always excellent and caring.

Very good experience with Emirates. Always i took thid company.

Very bad service and food variety will never come back again

Fantastic as ever. Great staff super catering and excellent service.

Always enjoyed flying with Emirates, flown with others but they don't really measure up. The others are cheaper without a doubt, but not as good as Emirates

The crew were absolutely fantastic. They actively asked if passengers wanted refills and if they were comfortable. I was extremely impressed.

Child’s meal was great along with other nice touches for kids.

Emirates did great! I liked the service, the food, cleanness, and the flight was on time. Much better airline than Qatar Airways I flew with last year.

The journey was nice, all the crews were very good and services are excellent

Great flight - Clubhouse met our needs, and the staff provided good service. Boarding felt a little chaotic, but given the size of the aircraft, it's always going to be challenging. Whilst the crew were friendly, the number of passengers meant that we received our breakfast items, but had finished breakfast before we were served a drink. Lunch was much better organised, and throughout the flight, the crew were attentive. Found the seats and ICE to be excellent. Disembarkation was fine, and everything possible to expedite the process was being done.

Nice staff, only one of the food services had a vegetarian option. Premium Economy was good - big seats and footrest. A little slow bringing welcome drink and often didn’t have the prosecco left on the tray - as though they are discouraging choosing that option. My only complaint is the wine/drinks served in a paper cup - I ordered a cognac on our previous flight and it came in the bottom of a paper cup, wine is poured into the cup like it’s a bucket!

Had a bad experience with crew member coming back Hong Kong to la the person next to me one of the passenger have taken video and picture of crew member the person that served meal young kid late 20' s 6 5'10 had attitude at his peak anything I asked for I don't know if it was bad day or racial I felt humiliated as people could see difference towards me I no problem with Cathy and my whole family never had one was very disappointed

Very attentive crews Flight was very smooth and safe Only little disappointment was the slight delay of departure (~30 minutes ) which rarely happen with CX flights

Not at all satisfactory. I had stomach upsets after taking food. Quality of Asian vegetarian meal was awful. Further there was no snacks/ fruits/ biscuits available as in between snacks.. only peanuts and pitzels.. except courteous staff rest of my experience was far from satisfactory

Later on, when there was no more bottled water, the water we received had a strong chlorine/disinfectant odor. On my flight from Hong Kong to Los Angeles, there was a male flight attendant who had a mean attitude throughout the whole trip, and he was very impatient during meal service “Furthermore, we purchased a Hong Kong SIM card as part of our flight package, but we received no instructions—neither by email nor SMS—on how to activate or use it. Consequently, we were unable to use the service at all. We request a full refund, as this appears to be a deceptive charge

Flight was kept super cold. I was shivering and had to layer up.

Multiple late or canceled flights. Lounge was 100 degrees. Food was terrible. The plane was incredibly old, and best of all, a screaming child for 3 hours. All for the low low price of $2,600 one way Hanoi to Shanghai. No idea how Cathay is ranked so high. Cathay is not much better than American Airlines or Spirit. In the future I will go out of my way to not fly Cathay.

The experience was very good. A little disappointed for the delays and the screen. The touch screen was annoying for being so irresponsive. Not a lot of good movie choices for me. The service is great. Food could have more choices though.

The flight experience was good for a long flight over the pole, but it got my wife to the Far East in time.

the crew was rude - there were no smiles when serving. they always had the look of why did you call me?

Qatar Airways has gone down over the last few years.

I paid extra for seating when first booking flight to be in a comfortable economy seat They still changed it to a middle seat regardless. When I asked for it to be changed back to aisle, they could only give me one at the back of the plane in the least comfortable seats.

I wish I knew in advance that the connecting flight was by indigo air

Qatar maybe considered one of the best ailines in the world but nowadays it is much of a muchness with the rest

Very efficient and professional staff. Food was good and so was entertainment selection.

The service was good but the food was a NO

All good. Over four hours flight if provided snacks like Qatar Airways would be better

I was travelling 3.5 years after. Agree Economy is no business class but the food was mediocre. Ordered a Hindu meal, the salads were bitter . The food was really below quality and had no tast from what I had in the past. Indian Railways probably have a better quality food when compared. However the kids meal was really nice and really appreciate how they were taken care of. The restrooms were dirty .

Overall the experience was neat with crew being nice and caring especially to parent with kids. The free snacks option was okay. The kiosk at Philly airport didn’t work.

Not sure how we end up with American Airlines instead of Qatar Airways. From Philadelphia to Qatar they boarded us then they asked us to unload. After 30 minutes later they board us again. The inside the plane it was burning hot and we were sweating like crazy. Crew members are absolute rude. The way they served the passengers were horrible. One of the crew members hit my knee with food cart and kept going. I was holding an ice pack for almost 2 hours. I am still with the pain.

It was very relaxing and staff were very quick to attend to any requests.

Air hostesses were great. Food was good. Flat bed is not that flat or comfortable.

Very disappointed to not have lounge access The shorter flight seats were uncomfortable

I booked tickets for a family of five and specifically paid extra to select our seats together. We spent nearly $1,000 extra (around $100 per seat) for extra legroom so we could sit near each other. However, despite paying for this, we ended up being separated on the flight. This caused a major issue for our family because my parents do not speak English and rely on me to translate and assist them during the journey. I do not understand why Etihad changed our reserved seats without explanation. I am extremely dissatisfied with this experience. I expect the airline to do better, and I am requesting a full refund for the seat selection fees we paid.

1 hour delay meant missed my connecting flight and 1st day of holiday

Awful the whole airline arrived to check baggage and board our flight and the airline desk was closed where none of the passengers could check in baggage, asked for a supervisor and was refused a supervisor, called the airlines from the airport and they refused to refund the flights for their actions in the airport, Etihad and Garuda Airlines absolutely horrible customer service all the way around.

Good one but just notice that you have to ask several time to get water or coffee .

It was mediocre. Honestly, the flight was late but that didn’t bother me as I had plenty of time. The only thing that bothered me is that the crew never asked to make the beds for us in business class. Maybe the crew was exhausted and that just didn’t occur to them.

I booked and paid for a Business Class seat for myself and my wife. 4 hours before the flight i get a call saying the plane they sent doesn't have the correct layout to accommodate all the business class seats they sold me 3 months earlier at a premium of $1500 a ticket. So they have to bump me from Business to Economy and will give me a $400 credit (total of $800 for both seats) that I could turn in at Abu Dahbi for $400 in US cash. They then promised a row that we could have to ourselves and the arm rests would go up so we could spread out for each of us. My wife was taken care of but I was put in the exit row with the flight attendents set as part of the three...and the arm rest did not go up. When we got to Abu Dahbi, they would not exchange our credit for cash as promised. Very disappointed they took my money 3 months ago and refused to reimburse for the change in seats or follow the promises made.

We have paid premium price for a business class Cabinet and we have received the old 777 with the following apart business class that is not to standard. It was very disappointing and it’s a very bad reputation for a premium airline company. This aeroplane should be the commission from being as a business class. We will pass this knowledge to our colleagues because the quality of business class in Etihad is not consistent and it is a lucky dip that sometimes you’re getting a good aeroplane and sometimes you’re getting their 30 years old aeroplane. The crew of the aeroplane have apologise and said that they hate this aeroplane and they have complained about it multiple times as well. Obviously Etihad is putting the economy in front of the Customer Experience. For the future we will not take this risk anymore and will fly with established company like emirates.
