It was good but n it to the same standard as London to Singapore

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.

The biggest problem was that I originally had a seat in the first row of premium economy as I had booked months earlier. I checked in and my boarding pass showed the seat in the first row as I had specified. When I got to the gate, the agent took my boarding pass and changed my seat to one in the last row in premium economy against the window. I had specifically booked the first row early for the legroom and for my ability to easily get out and use the restroom when I needed, since I do that quite often. The gate agents explanation was that the food tray on the seat in the first row was not working, so they gave me the seat in the last row. However, when I got on the plane, somebody was sitting in my original seat, and they sat there for the whole 14-hour flight with the tray working perfectly well. I was cheated by someone at the Cathay gate in Hong Kong. It was an outright, unforgivable lie by the gate agent or someone else at Cathay Pacific. I think this is very poor and inexcusable conduct by the people at Cathay Pacific. Perhaps somebody paid the gate agent extra money (bribe)to switch my seat and make it very difficult for me, or something else, but t was a sad experience and a very negative mark on Cathay Pacific.

They need to take training from emirates or Singapore airlines, it’s premium in pricing but poor in standards

Boarding crew at the gate mostly were being difficult. But one on board much better experience with crew and service!

Good. However the passenger in the search next to mine kept coughing. When we landed in Dallas we had to pick up.bags instead of going strait to the destination (which passengers do in Atlanta)

Although I am a lifetime Gold Premier member on another airline association, I was placed in a inside passenger seat on both legs of my journey from SFO to HKG and onward to NRT. However, i was lucky enough to have befriended two other passengers (who were related) in my row (row 62) and therefore was kept entertained with conversation for a large portion of the overnight flight from SFO to HKG. Normally, on a Star Alliance carrier, I typically can have the seat of my choice (aisle seat) and also a Premier seat (wider and longer legroom). I was a bit disappointed that no recognition of my Gold Premier status was acknowledged by Cathay Pacific on either of my flights on Sept 26-27. The food was actually very tasty unlike the typical economy class menu. Also I appreciated that the dinner drinks were served first (prior) to the main meal on the HKG to NRT portion of my flights but drinks were served AFTER the meal had been distributed (less appealing for thirsty passengers). I was happily that there appeared to have ample cabin space for most everyone's bags ---although I did have to pay more than $400 in extra baggage fees as I had brought 4 bags with me Overall, I was impressed by the diligence and professionalism of the flight crew.

In between two meals period they're not providing something like banana / cup noodles or bugger. It's really fell sad that I was asking have to wait for 3 hours for second meal. (breakfast)

The crew are timely, friendly and professional. I was very impressed.

They overbooked the flight and reassigned my seat. To add insult they lied that my assigned seat was broken and promptly gave it to someone else

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.
