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.

Crewmen at the luggage/bags scanning were very rude. Our flight from Manila to Guangzhou was delayed by an hour or so. With all the pressure we were already experiencing and rushing to get to our connecting flight, here comes these crewmen in charge of scanning our bags we're all shouting at us to rush. The delay was not the passengers fault.

Extra leg room in emergency exit row They actually played a movie that was in English. Not the first time I have flown China Southern, but the first time I had air control above. This is something I feel makes flight a bit more comfortable.

Food is terrible. They ran out of wine during first beverage service. Exit row passengers are not permitted to keep items under seat. Flight was delayed at take off and perhaps in route because we were over an hour off of schedule. Aircraft always had a line for the bathroom, two is not enough for amount of people and duration of flight. I do not know if there was bathroom in front, it was sectioned off.

Service was extremely slow, it took almost two hours just to get offered a drink. There wasn't any offering after boarding and I had to ask just to get water. The food was quite bad, normally I would choose the Japanese meal, however, both the Japanese and International options were poor. The staff seemed unorganized and did not follow a set protocol.

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.
