Paid a premium a have a shorter transit time in Hong Kong, but Cathay pacific rebooked me and ended up waiting for 10 hrs in Hong Hong airport.

Cabin crew is very helpful and nice, it is another level of service compared to Air Canada

Entertainment for kids was good. Good was terrible, needs lots of work.

The only problem I had was not being able to download my boarding passes prior to arriving at the airport. Everything else was perfect.

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

Short staffs, I ask stewardess to bring me cognac twice during dinner but they didn't bring it!

Flight was delayed at the last minute for six hours. Instead of delaying it to a normal hour, they moved it to 10 pm to essentially make it a redeye. There was no compensation or benefit offered for this inconvenience. Once on the plane, Inpaid for WiFi twice with both times it not working because of a “weak WiFi signal”, according to the flight attendants. They also chose the farther possible gates in both airports from the entrance/exit, even though they were one of the few active flights left so late in the evening. Overall it was pretty horrible.

I had high expectations but met with a below average experience. I hope the Airline will take a notice and improve.

I've stomach problems after 2 hours of flight, Iris, the flight purser not only did her best to make me feel comfortable, she went above and beyond providing pain relievers medicines and ointment. She look and found a doctor passenger on the flight to provide advise. She even report on ground staffs about my condition and provide wheelchair upon arrival. Kudos to her and Cathay Pacific!

So so, crew was overly professional and lacks human touch. Equipment is very old, especially the HKG-PVG CX366 flight. That plane along with its decor must have twenty years of history, or at least I had that impression.
