I wish there were more bathrooms available on these larger carriers.

My flight was suppose to be at 7:45pm to fly but it didnt fly out until 8:55 to dallas so then all of my other flights was late and delay ihad to wait at the airport for extra 14 hours to be able to get on a different plane

Super delayed. Unnecessary. Need more competent people doing logistics to keep things moving on time. Totally unacceptable.

Overall, not good. Super late boarding in Hong Kong because some last minute issue with a plane. The boarding process is chaotic. Kathy Pacific should seek to do better with punctual departure time. Caused a lot of trouble with missed connecting flight.

Not much of anything could have been done better unless I had a first class ticket. I was literally 15 hours with an airline in the economy class. Very professional friendly and attentive crew. Good airline food, clean cabin, seating area and bathrooms. I've been 4 times back-and-forth with Cathay Pacific, and I would not choose another airline for this trip. Five out of five stars.

Well- trained, cheerful onboard staff. Business class seating and storage were excellent. Outstanding range of food choices, though quality ranged from just OK (seasonal rice and beef dish) to outstanding ( congee and soup noodles with beef brisket). But what can you expect; it's on a plane. I couldn't figure out the remote control, but touch screen worked well. My wife and I (in our 60s), didnt find much to watch from the Entertainment choices. We mostly watched the flight maps. The bedding did the job but is unwieldy and ends up in a clump, with one-third falling on the floor.

Very friendly and accommodating staff. Food was great. Lots of movies and tv shows to choose from. Highly recommend.

Issues: 1) the charging issue as described in my previous survey 2) when I requested diet coke during the breakfast time, it is not available. Why? I can't drink diet coke in the morning? 3) when I tried to transfer to this flight, its gate information was not available to me?

The lead business class attendant was excellent. Made a point of greeting you and knowing your name by the time you leave.

A lot of things Never flying with this airline again Had an emergency landing

My seat was covered in vomit and I will be reaching out to Air Canada

It's kindof ridiculous that your system is even asking me about this since my flight was canceled and I wasn't rescheduled.

3 hr delay at the gate while they were doing maintenance. Next time, do not board passengers while maintenance is being performed

Digital check in is very poor with air canada compaired to other airlines

Baggage delayed we had to catch our cruise without any clothes 😒

Air Canada Rouge is great. Toronto Airport is the usual nightmare

Good but need to be better with the flight times.

The staff could not have been any friendlier. Lots of usb ports on our aircraft.

The staff was great and made the long trip easy peasy!

Air Canada cancelled our flight and reschedule it 26 hours later that completely interrupted my family's long waited Japan trip, it wasn't due to natural reason such as weather but under the company's control. On the day we wasted 9 hours of our time from 6am to 3pm, including a few hours in the customer counter waiting for supervisor to handle our rescheduling. When we came to the counter for rebooking help there were at least 4 employees on the counter but we were told they were not trained to handle customer rebooking, we were also told the supervisor could come 10:30 to handle our rebooking, but she showed up more than one hour later, the end result was exactly the same so the few hours we spent waiting for her was completely wasted; We already prepaid hotel and all the tickets for the our stay in Tokyo so all of the cost for the first day is completed wasted; The $80 meal voucher issues was far less than our financial loss due to the financial cancellation, and it was not surprisingly invalid (as Your company screw up everything possible along the flight), the vouchers were supposed to last 72 hours, when we tried to used it at our lounge next day less than 24 hours from its issuing at a designated restaurant, the worker there couldn't scan the vouchers after multiple tries on all 4 vouchers issued, so we had to pay the food from our own money; For the two return flights they were also full of unfortunate events that caused bad experience and further delay and waste of our time, both flights departed late and the last leg had another significant delay of more than half an hour after touchdown, the gate was for some reason not available so we waited more than half an hour, when we got out of plane it was almost one hour later than the supposed arrival time; The gate you arranged is the farthest in Vancouver airport, also was the luggage pickup location in Seattle airport; We also called customer service for rescheduling help and after a long time wait (more than an hour) we got a call back but the CS representative was equally clueless and unhelpful. Other than a fatal crash, your company couldn't do anything right and provided the worst service possible among the tons of flights we have taken in our lives.
