Missed our flight with Cathay due to late Westjet plane and chaotic Toronto airport. Had to clear customs get bags and re check bags in an hour. Did not make it got lost not clear signage with bag drop off. West jet only allowed 1 checked bag for this international fluid. Cathay checked my second bag for free.

Missed our flight with Cathay due to late Westjet plane and chaotic Toronto airport. Had to clear customs get bags and re check bags in an hour. Did not make it got lost not clear signage with bag drop off. West jet only allowed 1 checked bag for this international fluid. Cathay checked my second bag for free.

Flight was kept super cold. I was shivering and had to layer up.

More meal choice. There was only pork, beef and shrimp. I could not eat any of it and they had no alternatives

More tasty food particularly ethnic food. Staff didn’t respond to calls some of the time in premium economy.

Great. We received a meal even though it was a short flight.

I didn’t use entertainment But everything else was of excellent quality

Multiple late or canceled flights. Lounge was 100 degrees. Food was terrible. The plane was incredibly old, and best of all, a screaming child for 3 hours. All for the low low price of $2,600 one way Hanoi to Shanghai. No idea how Cathay is ranked so high. Cathay is not much better than American Airlines or Spirit. In the future I will go out of my way to not fly Cathay.

I liked the service. The touch screen needs improvement as well as movie choices.

Indian Vegetarian food was bland and I had to repeatedly ask for Salt. Movie selection is out dated.

My only suggestion is a way to not be woken up for food. … like maybe something you can place on you if you’d prefer to miss food than be woken up
