Excellent service in business class. Well worth the slightly higher fare as it includes lounge access, additional luggage weight and a full hot meal on board.

Excellent service in business class. Well worth the slightly higher fare as it includes lounge access, additional luggage weight and a full hot meal on board.

HAVING ANNOUNCEMENTS FOR PEOPLE TO BOARD ACCORDING TO GROUP IS ESSENTIAL N ENSURING N CUTTING OF QUEUES, EXCEPT FOR PRIORITY CLASS PASSENGERS ON A SEPARATE Q

Good experience although the boarding gate is at the terminal extension hence need to leave lounge to head over earlier.

I'm not interested in improving the airline. Therefore, I won't explain this in more detail. Next time I'll try a different one.

Seats were uncomfortable and the vegetarian meal was awful. Some of the entertainment didn't work.

Although booked meal of fruit only The crew had not received this special meal The same happened on my flight Bangkok / CAN The films are so old that best is to use own computer to watch downloads . Serve nuts but they do not warm up . Service is attentive , WC clean

Delayed flight in Singapore caused the transfer at Bangkok to be very stressful. Fortunately, no elderly were in this trip, else it will not be possible to catch the connecting flight. There were also several occasions throughout the flight journey where some of the passengers were not wearing their seat belts despite several remainders from the stewardess.

The aircraft was really old, the staff demotivated and the overall United airline service is horrible

Increase the number of available films, including variety. All other aspects were great.

food poor i said chiken i got pack a pow breakfast lousey .job to explain wot it was ...

Missed our flight with Cathay due to late Westjet plane and chaotic Toronto airport. Had to clear customs get bags and re check bags in an hour. Did not make it got lost not clear signage with bag drop off. West jet only allowed 1 checked bag for this international fluid. Cathay checked my second bag for free.

Vegetarian options should be included with every meal. Even just simple steamed vegetables and whole grains would capture a wide audience.

Cabin crew is very helpful and nice, it is another level of service compared to Air Canada

Horrible airline. Missed my baggage and don’t want to reimburse for the basis items. Pathetic customer service

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~

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

It as great, my in flight entertainment was malfunctioning though.

There is very little in the title" Premium" in the Economy experience with Cathay, Melbourne to Hong Kong. The seats are uncomfortable and the cabin with outdated 1990's decor and trim. The food service was sloppy and the leg room providing little to no advantage over regular economy seating. Infact, the Sunday flight was not fill occupancy and I would have done better saving the significant additional costs for the PREMIUM ticket and taken advantage of the seating. If you are a regular premium economy traveler of EMIRATES expecting the same experience on CATHAY, you will be disappointed. Emirates far superior.

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

I traveled to Singapore for 5 days, I didn’t receive my luggage until the 3rd day. When I received my luggage was broken which they fixed it supposedly. I never had such a poor experience with the any other airline. I honestly think it should be a compensation for all of my losses and suffering that I went through.

Seats were very comfortable and the staff too was very friendly.

I liked the crew, the food and the foot space. I did not like the comfort of the seats.

More leg space than other flights, but *maybe* narrower seats

More leg space than other flights, but felt like *maybe* narrower seats?

second leg was more comfortable. Customer service in Abu Dhabi is okay.

Needs better seat for business class. My seat was falling apart. Also no WiFi on that flight

Boarding catastrophic let alone have to claimb the plain rather than using jetway. 5.5 hr delay leaving had to do stop in Lgw for a new crew which further compounded the delay. Connecting flight would not wait and had to pend a night in a hotel. Curiously my seat would not go full flat.

Crew was good, boarding mediocre, food choices were limited, seating was not comfortable

I travelled from Adu Dhabi to Melb; service was minimal at best, when I asked for a bottle of water but no meal I was told it was not available- it seemed a cup would do. The staff were un helpful & dismissive. We had a family near us who I never saw obtain any assistance from crew- they were simply avoided! Meal was simple and adequate no hot drinks were on offer until close to arriving, with a pseudo breakfast. Seats were tight despite obtaining extra leg room. I will not be flying with Etihad again and will not recommend them to family & friends.

The seat was not functional. Very uncomfortable to sit upright for that many hours😢. There was no legroom. Can’t move the legs or the body. We should have the option to pick our seats. There was no need to call customer support team and have them pick and we pay for the premium seats. When I called the CST regarding the seats, their response is gaslighting. Total disappointment. We have paid to be tortured by Etihad Airlines.
