The flight attendants were very helpful, efficient and courteous in helping everyone!

I love the comfortable business class seats. The service was excellent. Staff was friendly.

The staff were so friendly and accommodating. The food was great. Lots of movies to choose from as well as tv shows. Highly recommend.

Better. I took an aisle seat this time. Although the overheard compartment above the seat ahead of me kept opening up during flight.

If I had blood clots, that window seat would've killed me for certain.

I have a Peanut Allergy and the Steward staff were very accommodating in ensuring my safety as my allergy is life threatening. Very professional and so vested in their profession.

My seat was sold off to someone else. Had to wait 9 hours to catch the next filght. Definitely will never use Cathay Pacific again. Bad, very bad airline. will comment on google reviews too.

The crew were fine. I didn’t enjoy the food at all. I found it unappetising and really had trouble eating it. The comfort level was fine and our return flight is with Cathay Pacific but honestly I probably wouldn’t fly Cathay Pacific again.

We requested special assistance and Cathay Pacific provided it in Sydney, but we were completely forgotten about in Hong Kong - when we really needed the help to catch our connecting flight. Really disappointing service.

The staff were excellent considering it was a jam packed flight. We had to wait nearly an hour for our baggage to appear on the carousel. That was a real shame.

It was ok, but not what it was like 20 years ago

Great food and good entertainment options for the long flight.

Excellent as always, I won't fly to Australia, and back to the US on any other airline. The flight crew is always top notch, and have a way to make one feel extra special. Thank you for your service, I would rate Qantas Airways a 10+.

No internet on flight, which makes log travels really hard.

Overall good experience with flight and airport wheelchair staff. Also got Indian food in the flights

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

It was so hot on the plane mixed with being quite turbulent and a rough landing. We all felt very nauseous for hours afterwards. Crew were lovely though.

All things were below standard. There were 2 crew on the flights but didn't ask for water. The flight connection was poor for 4 hours.

The service and smooth landing. Food was delicious and the staff was friendly. We arrived earlier than scheduled.

Ease of boarding. Staff were friendly and helpful. Food was good. In flight entertainment great.

Not the greatest. Our initial flight to Tokyo got cancelled due to mechanical issues, which was unfortunate however they worked quickly to get us on another flight and refunded my seat ticket. We flew with Air Canada back home and it was not a good flight. The crew never gave us our second meal and I was awake the whole flight so I know they did not come by. The flight itself was rocky and seats were uncomfortable. In general, for an international flight, I do not think it is fair that we have to pay extra to pick our own seats. I’ve been on many international flights and always had the option to pick my seat during the booking or at online check-in. Furthermore, if the airline is going to automatically pick your seat, it should seat groups together instead of seating them apart. If I already pay thousands of dollars for a flight, I should have this option included.

I cancelled my flight in March and have been waiting for 3 months for the refund. Both flights have taken off and returned now and still no refund.

great flights both ways on time both ways.staff(ladies) where great at check-in.

Food was great, I wished there was better options for movies.

737-8 Max is an awful design. Toilets in the rear are inaccessible for most of the flight due to service carts.

Flight was first delayed for 1 hour, then was cancelled. Communication was poor. I ended up booking a new flight on a different carrier to return home. I heard people in my gate area on the phone with Air Canada customer service who had to inform them that the flight was cancelled and they weren't being helped because the system hadn't caught up with what was actually happening.

Other airlines offer free wifi to business class customers, Air Canada does not

Every flight was canceled and they didn’t care much about their passengers

Crew attitude and attentiveness. Comfort of the seats. Entertainment options.

this flight was exceptional due to the plane itself being updated with longer seat belts so no need for the extender and access to a tv.
