A wild adventure through China.

The "flight" was a bus ride that the airline knew nothing about so we had to fend for ourselves and figure out how to get to Shanghai. Took a bus a taxi and then another bus through China speaking no Chinese and not really having any idea of what was going on and if we were going to make our next flight. It took us about 6 hours of travel and headache and the airline didn't cover the taxi or bus charge.

We booked this flight months ago and made plans to meet people. We wanted to arrive early to avoid traffic but since the flight as 3 hours delayed we arrived at 5 and did not get to the hotel that was 20 miles away in 2 hours. When I am late for my flight you cancel my ticket and make me purchase a more expensive one. More than the round trip I purchased so why don't you compensate me when your delayed

Your tardiness and inconsiderate way of doing business. Your irresponsible attitude towards your paying customers.

The crew is nice. You can order snacks in between meals.

Our flight was cancelled and we were automatically placed on another EARLIER flight and we weren't notified. I found out the morning of our original flight, as our new flight was about to board. I still haven't figured out who was responsible for this snafu - the airline or Webjet.com. Webjet customer service was horrible and offensive when I tried to explain to them what happened; they said it was my responsibility to check the time. I would disagree - the customer is ultimately supposed to get an email notifying them of the flight change, giving them options. Based on that phone call with Webjet, I will NEVER do business with them again. As for the flight cancellation issue - if Kayak could help me get to the bottom of this, that would be appreciated.

fter serving a meal, it was 7 hours later we received any beverages. the cabin air was very dehydrating and everyone started coughing because we had been given no water. this is how people get sick and spread diseases. the plane definitely needed to consider hydration. and when they finally served us the meal, they didnt offer water rather coffee or tea and i had to ask for water and juice. the cabin temperature also fluctuated from hot to cold.

I ended up wasting an entire day Monday and spent another $460 buying a last minute flight because I showed up Monday at 9am at lax to find out my flight had already left Sunday at 10:30pm. As you can imagine it was very stressful driving 2 hours in traffic to GET to lax early to only find out they wouldn’t allow me to board the 11:30am flight with China eastern because my flight was SUPPOSED to be with CHINA Southern Sunday night.

If someone could please call me to discuss the $460 I had to pay Monday evening and the day wasted Monday December 4th I would be grateful. I have booked with kayak.com in the past and have never had any issue. For some reason kayak emailed me the wrong boarding time and airline

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.
