The crew is bilingual and they work and move fast

Flight CX882 Seat 59K the food tray does not stay up, food keeps sliding to the right. Both departing and returning flights ran out of free gifts as stated for the purchase of Laneige skin care products. Food selection is less desirable compared to other Asian airlines. Inside the crew food storage/service area looks old and dirty. I can see the area from my seat.

JFK
Mediocre 3.6

Plane was clean

The crew was uninformed and unobservant to actual conditions in the cabin. They kept the air conditioning on and no one was available to address the situation. People started to take their winter coats out of the overhead bins and sit in their seats with coats on. They spent a significant amount of time repeatedly requesting that the window shades be moved up or down. Frankly, if I buy a window seat I should have the option to look out the window if I'm not disturbing my neighbors.

Entertainment even in economy class was excellent -- tons of movies, games, etc. Cabin crew were friendly. Bathroom was very large.

In economy, seating was incredibly tight (very little legroom) and at least in my seat, very little reclining. For a 14 hour flight through the night, it made it very difficult to actually get any rest. Food was OK.

I bought a round trip ticket online with my current passport number. When I arrived in Shanghai, I was held at the Customs for extra 20 or 30 minutes because the airline provided a passport number I used more than 10 years ago. My luggage was held at Pudong airport quite a few days. Each day, they said something different to me... When it's the time for me to go back, I was held again at PEK, because of the different passport number they kept in their system. Even though I explained to them how I purchased the ticket with my current passport number and I have no idea where the problem happened. They insisted that it was my own fault. My gmail did not work properly in China. I asked them for help by providing me the ticket agent contact info in the States. They said that they did not know. I should go where I bought my ticket. I had to spend hours to contact friends in the States to find the phone number of justfly.com. Then, I made international call to justfly for about hour to have the problem fixed. I did not provide any wrong info when purchasing the ticket. The problem was made between the airline and their agent. They, as professionals, could easily have the problem solved but they blamed the customer for the mistake. I had to spend so much extra time and money to cover their mistake, at the risk of missing my flight. That's the worst experience I ever had for international flight.

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,
please send us an and someone from our team will get back to you promptly.
