Really appreciate the water offered in addition to the beverage service.

On this flight, seemed like attendants just went up and down isle collecting garbage and recycling. I must have heard it 10 times, which was annoying. Serving a snack/beverage was appreciated. Collect rubbish twice, not 10 times, chanting up/down isle calling out "garbage....recycling......garbage.......recycling........." etc. All else was fine.

I described the issue I had with getting to the flight in my previous comments.

There was a engine problem, so we had to deboard and wait on a new plane but that just happens sometimes, and crew was very efficient and nice.

Cathay Pacific is an excellent, well-maintained airline. While I too would love to fly first, or business class, I did not. I actually had the dreaded middle seat in the middle row, and yet, since I am an inquisitive traveler, I introduced myself to my row mates and had nice chats with both until lights out. Pro tip: Bring a donut travel pillow no matter where your seat is! The flight was smooth, the restrooms clean and the staff courteous and efficient. I gave the comfort level a 4 because of the reasons listed above. The airline meals... let's face it ... it's airplane food but CP does a good job in making it as edible as possible.

I was not able to figure out how to get the entertainment. But the flight was smooth and quick.

you have to buy the wifi for entertainment. flight was packed but crew was nice.

Again, the Alaska boarding area at Sea-Tac is gross.

It was fine but the Seattle airport was terrible. It took over 2 hours to get from rental car return to gate! There was no one to help with check in and bag drop. It is not a people friendly airport…too long to walk, too many levels, no help. If it is possible to pass this on, please do. It seems it is Alaska’s main airport.

Nobody’s fault but turbulence all the way meant no service and no access to the bathroom,
