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.

My bag didn’t make it to the final destination. I was one of many people in the same situation who made the same journey originating in SF and ending in Bangkok. We had an almost 3 hour layover in Guangzhou, so I doubt that there wasn’t enough time to make the bag transfer.

Nothing spectacular to mention.

Airline scheduled only a 30 minute layover between Shanghai and Hong Kong. Obviously I missed it. Waited 3 hours for airline to put me up in hotel. Hotel was extremely sketchy. I'll never make the mistake of traveling with this airline again. Worst travel experience in many years, and I've been some rough places. Food was Terrible, too.

The staff are very efficient and professional. The food was much better than I expected. We were given pillows and blankets . Bathrooms were clean .

The only issue with CEA was checking in and boarding. It was brutal coming out of Bangkok. I’m not sure if this is the fault of CEA or Bangkok Airport.

Ground staff did not want to help me and refused to put me on this flight because they reffered to no transit visa, although I was legally allowed to get on the flight as I have just found out, but it is gone already. As a result all my consecutive flight were cancelled as no show. I tried to reach the airline help line, however due to Chinese New Year they don't work, so there was no way to solve this problem I am VERY dissapointed. Will take this case to the court if my money not refunded

The staff spoke English very well at ICN, which was a nice change compared to China, where I live and work. They listened and understood my concerns, especially about having little time between flights, not knowing what to do next, and needed their assistance with getting my luggage forwarded.

Usually I love ICN airport. I was not aware there was another terminal, kilometres away by shuttle bus, that I needed to use between flights. If not for the extremely helpful information booth staff at station E, who arranged to have my luggage forwarded to my final definition, barely in time when the flights were purchased separately, I would have missed my flight trying to get my luggage then check it again, in addition to all the other steps. This time, I found the various steps in the procedure unpredictable. The signage is great but I didn't know what I was to do next.

We flew economy, so didn’t have incredible expectations. The seats actually had more legroom than expected and reclined well. No complaints for what it is.

The food was pretty terrible, even for airplane food. On a 14.5 hot flight we had 2 full meals, along with some snacks which was decent frequency. However it was so inedible! Luckily we packed our own food just in case. The crew was also pretty terrible, and not because of a language barrier. Didn’t seem to know the basics about food and drink service and often skipped service to people wide awake and waiting.

The 3 employees at the counter got together & solved a glitch in our Australia visa that was priventing them from issueing bording pass for our second leg of travel They were outstanding & also unexpectedly we received a hotel respite for our 8 hour layover in Guangzhou! Smiling flight atendents. This is my first travel with China southern On the other hand during 6 wk prior to our trip we were unable to get anybody on the phone to ask Q or reserve a seat.

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

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 prices, so it’s not possible for us to guarantee what other companies are selling.

We aggregate tons 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 don't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car hires 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.
