I didn't know when I was supposed to board or what the process was, and the crew wasn't helpful to me when I asked. Maybe language barrier?

Food was good. Flight attendants were good.

Tiny beds in business class with two-across seating so the window passenger has to climb over the aisle passenger. Are they stuck in the 90s? I won't fly with them again. Boarding in Beijing for Manila was a free for all. Business class was not called first. Isn't this why I pay triple the coach fare? No English language newspapers from Los Angeles to Beijing.

The people were excellent.

I had planned to check an extra piece of luggage, gifts and purchases for church needs. They wanted to charge me $3,655(!!!) for that. Absurd. I had to leave the suitcase behind. I will probably fly on a different airline whenever I go to Russia now.

Service was nice.

Comparing to recent businesses class flight on Emirates; Singapore airlines seat does not recline to flat bed. Boarded flight st 11pm and arrived at Singapore at 7am. Toiletries like tooth brush and paste, razor etc. were not provided. Emirates provides, so we did not pack in-flight.

They came around often to see if we needed water or anything. Food was good.

It was way to hot on the plane, I actually couldn't even sleep because I was sweating so much. They give out blankets so I would think it would skew to the cool side so people can adjust themselves. Nothing you can do when it is too hot other than suffer.

Despite somewhat limited English skills, the crew were very professional and pleasant. The flight was overall, a wuccess, and I would absolutely fly air china again.

The food on this leg of the trip was hit and miss. The food o. The first leg was very good. They have a ways to go to being their catering up to the level of some other airlines, he is been an overall positive experience.

I accidentally left an external battery in my check in bag and they stopped me to open my bag and remove it as I was boarding. This is obviously my fault but I wish they had called me up earlier to not disrupt the other passagers and slow the boarding process.

My United connecting flight was delayed. I rushed to arrive at the gate prior to the departure time to be told the plane had left early and I had been rescheduled to the next morning at 7am. However, there were no vouchers available for me to stay in a hotel or get food. So, I was able to get a flight on American that got me home the same night. By the way, the American flight was delaying takeoff to wait for passengers who had been delayed on their connecting flights.

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.

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.
