Love that everything is included. Food, drinks and entertainment. The crew were great and nothing was too much trouble.

Boarding of the A380 was ridiculous. We were lined up well ahead of boarding, then moved to another line, then moved again. Once we were lined up we had to stop and start, other people were pushed to the front again and again. This could have been solved by leaving one lane free for people sitting upstairs, or 'preferred' fliers. Instead everyone was pushed back and had to wait. I've never seen an aeroplane boarded so badly and we ended up being some of the last people on the plane. Badly organised and just plain awful.

Staff were helpful while checking in.

I don't understand how paying for checked bags ahead of time would be priced any differently than doing it at the check in counter, but the difference is exorbitant. It's a cheap airline for a reason and they get their money back by charging you for everything, including water during the flight. It's better to pay a little bit more for a real airline where standard things like carry ons, checked bags, water, and drinks come complimentary, especially for long flights.

Everything about our flight went very well, and most were better than expected. The crew were very helpful. Our seats had plenty of room in economy. This were done very efficiently and with concern for value.

Our Vegan meals were rather tasteless and uninteresting. The only entertainment was what we brought with us and overhead monitors.

Crew and staff are professional and worked well together, fairly efficient

Upon landing, there was a problem with airport customs and immigration which prevented the passengers from leaving the plane. Crew needs to be more proactive with (1) passengers getting up too early and blocking the aisle out of turn. An elder woman was trying to get her bags and exit her row and passengers from behind were not letting her collect and exit. I stopped the rude people from the back who were getting off out of turn. Instructions need to be issued, let people get off the plane in orderly fashion. and (2) crew did not inform passengers what was happening with immigration and customs holdings things up until I hit the service button a few times. Tell the passengers what is going on rather than allow tempers to heat up

There was no approach by staff to warn the waiting queue to do this. We were given boarding passes and told to try our luck taking the luggage through security and try gate baggage check. We made the plane 20 minutes before scheduled departure

First, crew and service were wonderful. Business class food was very good. BUT on the SF/Guangzhou route, both ways, business class seat 14K did not work! These are 14 and 12 hour overnight flights and seat wouldn't even recline, forget laying flat! On the outbound flight I didn't realize until we took off. The crew tried to fix it and couldn't but gave me one of the crew seats in the back of business class. Not great to be separated from my husband for most of the flight, but I could sleep and was otherwise comfortable. Returning Guangzhou to SF, had the same seat. Checked it as soon as I boarded and it didn't work, again! This time they got ground crew to fix it before take off. It worked most of the flight, but once I put it up after laying flat for 8 hours, it stopped working. Would not move from a straight upright position. Ridiculous! SO check to make sure your seats work before you take off!!

I was upset because I had to wait 6 hours now and go back through security again. I asked to speak to a supervisor. They pertended not to understand. I was persistant and then they siad oh here is a seat on the 1:00 flight. Then he goes do you want window or aisle. If there was no seats whey do I have a choice?

The flight was delayed due to air traffic control. Subsequently I missed my connecting flight -- Xiamen to Manila that evening and had to spend another night in China. Next flight out of Xiamen was 6pm, Nov 2. Xiamen ground staff was very helpful in booking me the option to fly China Southern to Guangzhou the night of Nov 1, stay for free in a hotel, and then take the 0835 morning China Southern flight from Guangzhou to Manila. It was difficult to identify the right people to speak with and get clear assistance and direction in both Xiamen and Guangzhou.

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,
