In flight entertainment system was good and had a nice selection.

Almost could not board my flight back home from Korea as China Eastern changed the departure time of my connection in Beijing by 20 min. After dealing with customer service for over an hour they let me board the flight I already paid for! Middle isle, middle seat at the back of the plane for 14 hours. 1st meal had a very fishy smell so many on the plane didn’t eat it. Someone was smoking in the bathroom too which added a nice smell to the cabin. 2nd meal was a bit better. My seat was pretty tight. (I am 6’2” 230 lbs) Every time I take China Eastern I think to myself never again, but every now and again I have no option. Customer service is almost non-existent if anything goes wrong. They are the only airline that I have issues with almost every booking.

The food was amazing two hot meals and a couple of snacks.

Economy is not the way to travel on an extended flight, aisle seat is bearable but otherwise a fail in the comfort side.

It saves so much time getting to Toowoomba. The flight crew are friendly and you get a complimentary snack pack and drinks - unlike so many domestic flights these days. It's rarely full so you can normally get a row to yourself if traveling alone.

The seats aren't the most comfortable - but no airline really is. It's a small plane so it is extra noisy. If you have noise cancelling headphones, wear them! It will make such a difference.

the first class seats from HK to SFO, IFE, service, dom perignon, red wine, excellent attention, greeted personally by four of flight team, provided flight details personally. Im 6'0" so the bed was a little short. it was simply a wonderful experience.

the IFE is not touch screen and pausing on the hand held was fidgety, but a huge 24 inch screen and beautiful.

I flew from NY to Phuket via Cathay Pacific which is a 22 hr flight! The crew was pleasant and friendly and took excellent care of my family and I. I would fly with them again anytime.

My only complaint, if I have to make any suggestions would be more leg room.

Comfy seats and the entertainment for economy class were the best perks and price as well. Flight was also on time.

The food was just awful. 2 meals were provided and both were chicken or beef with junky dessert. Bring your own food.

I was NOT able to choose our seats, so we couldn't sit together and were in the last two rows, in middle seats! It also took us 15 minutes to jog to the opposite end of the airport to just make our connecting flight. I would not fly with Cathay again!

There were a number of flights leaving from the same gate within minutes of each other and the staff handled it without a hitch.

The food was not good, pastry type meat pie and flakey chewy dessert pastry.

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.

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.
