Was not able to board flight because boarding pass name did not match passport name and no one caught it.

The flight attendants were very helpful, efficient and courteous in helping everyone!

It was great. It was my first time with Cathay Pacific and I really recommend.

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.

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 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.

Food was hood for airline food with good poftion and variety in meals. Frequency of beverage service was very low and amount of soda with meals was inadequate.

The employees are very nice and good. The delay due to the aircraft is not a good thing. Planning for such problems should be an easy task.

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.
