The style of the pillows and blankets were nice. The pillows were really comfortable and a good size. The taste of the food was okay. I honestly expected a horrible experience, it was not fantastic but it was better than what I anticipated.

The sealed blanket had white hair as if from an older person. Although I liked the pillow, on my return flight I used it to sleep, I used it for my back the entire time going, when I got home I noticed I was developing a sty on my eyelid. My companions noticed that the sometimes when he received his food it was still cold in some parts. On my return flight there were a few times my row was skipped for drinks. On my return flight the stewardess seemed hesitant when I asked for an additional drink. I ordered tea and asked for water. The gate agent in Beijing was extremely rude and unhelpful, she ignored us and even tossed our ticket back at us when we tried to ask about our seats for the flight.

Seats had good headrests with adjustable "wings" to cradle head while sleeping. USB plug below entertainment screen.

A good half the plane was first class and business class. (This was a 15 hour Hong King to Boston flight.) They handed out a fancy menu with 4 entrees but by the time they got to economy only pasta was left. We did at least get a small bottle of water; on our outgoing flight they doled it out in meager glasses. When boarding in Hong Kong we had to go through an additional security check between the gate and the plane (that was a first...) and had our water bottles confiscated. So we were reliant on what they would give us on the plane. Seats were tight, unlike some airlines that give you a little extra room. Wouldn't fly again unless their price was a real bargain.

I enjoyed the good check in service, and the excellent lounges. As always, the overall level of service on Cathay was good.

The utterly appalling seats on Cathay's old B777s are unacceptable for a premium airline. Non-reclining economy seats which are desperately uncomfortable for any flight of more than 1 hour, and completely unsuitable for an overnight flight. These planes desperately need a refit. Best avoided until this has been completed. The flight was overbooked, and the cabin crew seemed stressed and very busy. As a long term frequent flyer with CX, this was a very disappointing experience.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
