Felt like the oldest plane in Asiana Fleet. Screen was 5-6in only and no charging at all. Movie selection wasn't great.

Felt like the oldest plane in Asiana Fleet. Screen was 5-6in only and no charging at all. Movie selection wasn't great.

The staff was courteous and the flight was very smooth. It was so nice to see the captain greeting the passengers at the end of the flights.

It was all perfect and very pleasant for such long flights

We took business class, It was comfortable and I was able to sleep.

Everything was perfect. A flight attendant even brought me snacks after I declined food due to my desire to force myself to follow the destination time zone.

Great service and comfortable seats. The first meal was excellent but the second meal was only satisfactory

The legroom in economy was better than other airlines. Since my legs are long, that means a lot. Also, the A380 from Los Angeles to Incheon gave passengers a smooth ride. Everything went smoothly from boarding to disembarkation in Incheon. I'd fly Asiana again!

It’s wonderful service aboard. Delayed for departure but arrival in Korea went so well.

Seems like crew assumed you're korean. Not impressed by crew

The seats (legroom) are tight and chairs cushion is stiff (not comfortable). The crew was courteous, professional and friendly. There was no food / snack for this flight (very short flight, but still would be nice to provide some snack for the enjoyment).

Great! Internet is below its competition. Poor connectivity quality and speed.

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

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.

Overall, it was a very good experience. I would have given it a 10/10, especially based on our flight from SFO to Melbourne. The cabin crew on that flight were wonderful and incredibly attentive. They took extra care when setting up our beds so we could sleep comfortably without being disturbed. Dinner was served promptly and smoothly. I woke up quite late, when the flight was already preparing for landing, and the crew still made sure I was taken care of. They brought me English tea in a proper cup, and when it was time to prepare the cabin for landing, they thoughtfully transferred it into a takeaway cup so I could continue enjoying it along with some breakfast. Those small, thoughtful gestures made the long flight feel much more comfortable and special. The service from the SFO to Melbourne crew was truly excellent.

From start to finish, every part of the experience was outstanding. The care and kindness shown to my 95-year-old mother was exceptional—truly 10 out of 10. From the assistance she received at Sydney Airport while boarding the plane to the help she was given when arriving at Wagga Wagga Airport, every staff member was friendly, professional, and genuinely caring. They made her feel comfortable, safe, and well looked after throughout her journey. A heartfelt thank you to everyone who helped make my mother's trip such a wonderful experience. Your compassion and dedication are greatly appreciated.

My flight with Qantas was excellent, the crew were exceptional, the food was very good, and the seats were surprisingly spacious and comfortable. I was extremely disappointed when my checked bag did not make it onto my connecting flight, but was pleased with the ease of filing a report of a missing bag with Qantas at the Auckland airport - there, my pleasure ended. I can see, with an apple tag on my bag, that it is still in Sydney and has not moved in more than 30 hours. I shared the tracking information with Qantas and was assured when I filed the missing bag report that my bag would be delivered first thing the next morning on the next flight from Sydney to Auckland. Qantas' missing bag tracking feature still lists its status as "searching for your bag, check back later" more than a full 24 hours after filing the report despite my having shared tracking information, a photo of the bag, and calling the customer care line and being assured that an "urgent action message" had been sent to the team in Sydney. The lack of communication from Qantas' customer service department and the lack of action after an incredibly expensive business class ticket price is outrageous and has, definitively, affected my willingness to consider flying Qantas in the future, much less on long-haul international flights with high cost airfare.

Going from Sydney to London on a single flight number was very convenient, not having to worry about changing planes. Entertainment system on A380 economy cabin is very dated. Lavatories are small. The self serve refreshments have been significantly reduced since the A380 first started.

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

Great food and good entertainment options for the long flight.

It seems that qantas are trying hard to regain their status as Australia's premier airline. I only flew economy but happy with the service entertainment, food, configuration everything.

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

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.

Air Canada was fine but air Canada rouge and air Canada express was terrible with luggage delays. First flight was cancelled so my luggage did not make it to my destination with me. The second flight returning not sure why but my luggage did not make it on my connecting flight. Overall terrible with handling luggage.

It would be nice to have access to the headphones since wifi wasn’t available. Passengers in front of me got them for free I was asked to pay for them. I heard stewardessa saying that headphones are complimentary since there is no wifi. When I requested headphones I had to pay. No room to sit. Bear given with the can but my drink was given in plastik cup. I will try not to fly with air Canada any more.

It was a poor experience.A decline in what I was use to when travelling internationally

Boarded on time and arrived early. Overall quick flight. Snack and beverage offered.

Delay caused us to miss connecting flight and 3 hour layover. All connecting flights my wife and I couldn’t sit together. Once arrived luggage arrived 4 days later

Terrible 12 hours delay Terrible We lost our suitcases No medication with us nothing

Enjoyed the A330 comfort, and the inseat entertainment. Horrible disembarking experience. No gate when we landed to sat on tarmac for 40 minutes, and missed my train.

Awful, I was bumped from my buisness class seat because the airline decided to forfeit my seat to a pilot and stick me in the very back of the plane. My flight was delayed by an hour, boarding took an extra 30 minutes longer then it should have, and the in flight entertainment system was broken for my entire flight. I have yet to hear from Air Canada with regards to a refund for my ticket so in total I'm down about $1400 dollars for my tickets. Moving forward if I can avoid using Air Canada in the future I will be doing so even if it costs me extra money.

Unfortunately, my experience with Air Canada was not as great as I had hoped. The flight attendants were not very friendly or welcoming, which made the overall experience less pleasant. I expected better customer service and a more positive attitude from the crew. I hope Air Canada takes this feedback into consideration and works to improve the passenger experience.

Flight was late missed our connection to Indianapolis no hotel rooms really difficult finding a room hope to be in Indianapolis one day late and multiple flights to even get there.
