Pros: Crew is wonderful .they do everything in business class to make you feel comfortable

Cons: I will never fly China Eastern again. EVER !! I need to add an extra day or two onto our flight. We purchased business class flights so they are not cheap. In order for us to make a change they want $1700 each person, a total of $3400 to take the same flight two days later. The fee is the highest I have ever hear for the same flight class .. I will never ever use China Eastern again, they are taking advantage..I could actually buy a return ticket on another airline for cheaper than they want for a flight change.

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

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.
