a longer gap btw the supper and breakfast would have been better - felt like the sleep was way too fragmented on this red eye flight

I loved the full Taylor Swift selection but felt that the other selections were limited, didn’t span the popular music eras nor a wide enough range of music genres. BUT the seat and bed were GREAT (it was wide, long enough, had great storage, firm enough to uphold body postural comfort). Outstanding crew and really great food - gourmet innovative dim sum breakfast so different from the boring standard fare offered by many other business class products.

The consistency with Singapore Airlines is fantastic. Crew are always brilliant and food delicious in business class

The business class seats were very uncomfortable. When in lie flat position my legs were very restricted.

It was very good experience on board to Sydney with SQ.

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.

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

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

Transfer within the same terminal and lots of facilities at the airport.

Very slow check in. Food poor and some of the special meals offered were not available. Luggage then didnt arrive and still waiting for news 48 hours later

It was a good experience except that the flight has been rescheduled, bit disappointed but it happens.

Everything was good; they still provided a sandwich snack. Good crew

My flight was delayed by 8 hours I arrived at airport 4hrs earlier but to see if they can reroute me to get my connecting flt to Hong Kong. They auto rebooked my flt. With no chance. Which I missed this entire reservation through kayak. My next flt they got me on was at 6 am. Misses an entire day of my trip abroad all my accommodations seat assignments were missed and missed adding my TSA precheck to my ticket as well as my vegan meal request so I didnt have meals on any of the flight....so not a comfortable experience. Please help me with accommodations upon my return.

The crew could have awaken me to eat dinner!! I was so waiting to order the braised duck breast and fell asleep b4 crew got to me to take order. When I awoke, lights were out and food had been served without me eating. I did love the apple juice!

Boarding was good and efficient, however since this was a late flight I spent most of the time sleeping so can't express any further opinions

Previous flight with Cathay from LAX was delayed thus missing this flight to KL by 12 hours. This in turn missed other travel arrangements from KL. They did provide overnight accommodation in Hong Kong.

The flight was delayed for over an hour, which made me worry about pets in cargo.

It was good, on time boarding. Have a good service. .

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.

Business class points redemption - good value for points paid, dubious value if out of your own pocket, domestic class business product okay for this length of flight. The flight left and arrived on time, crew were good, aircraft was a bit old and tired, but still miles ahead of their competitors in Virgin and Jetstar.

Was bumped to a later flight because of inefficiency on part of the airline.

Very good as always, stand out airline. The passengers whom choose to stuff baggage that otherwise should be checked-in is a real bother but that's not the airlines doing. A real frustration that passengers just don't want to check-in luggage. This is a pet hate unfortunately.

The old Plane had not been cleaned properly in a long time.

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

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.

Plane a little late departing, but not an issue. The pilots humour when he said “I will try to make up some time…. I know a few short cuts to Adelaide” made the passengers chuckle. This is what makes Qantas “Australian”.

The staff we fantastic and seemed to work very well with each other

IFE didn't work. Wifi didn't work but they eventually managed to reset it. Our original flight was cancelled, so rebooked onto new flight seated apart from travel partner.

No individual entertainment screens on this flight. Would have been nice to know beforehand.
