Mediocre 2.6

Cons: 1. I am not sure if your crew members could speak English or not. I didn’t understand what they were talking about or what was happening. 2. The plane took off under extreme thunderstorm. I am not sure if this was safe to do so but the plane was extremely bumpy, going down rapidly for about 30 minutes. The whole cabin was then in chaos. People started turning up, crying and writing last words. However, your crew members GAVE NO INSTRUCTIONS, BROADCASTING OR UPDATES ON WHATS GOING ON. What they did was mocking around with each other in Cantonese. 3. This would be my last time travel with you - I was your loyal customer since student time. But after this awful experience I chose not to go with you anymore.

Pros: I was stranded by not being aloud to board the plane there was a visa problem at my destination the air China staff required me to have a visa to enter the country of India. There is a tourist visa for under 180 days stay. That’s what I get when I enter on a land route just a 60 day visa upon arrival so the agents would not let me board. Air China sent me a note that I could cancel the flight and should be able to get a refund. I have called 6 times already and have yet to speak with anyone I stayed in the station all night and at 9 am today they will give be a number that will work

Cons: I would like to get a full refund

Cons: They said they understand situation but they were afraid to solve but there were staff name Ms. Umeda Ms. Yasukawa and Ms. Ai were very nice trying to handling the situation but as we were very cooperative and understanding that not their fault. My parents are old my mother can’t walk probably and Blood pleasure patient. I ask for room in Beijing because of 18 hours delayed stay. But they failed for get Hotel. But Japanese staff were nice also crew. I would love to give 5/5 rating but honestly was bad experience only because of delayed flight and couldn’t get recovery.

Cons: Too much turbulence! It was quite uncomfortable for a long time. There were not enough comforting announcements from the flight deck to explain it. Crew members need practice in pronouncing English, and louder. Crew volume was too low compared to captain. American movie selection was too limited.

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.

More questions or if you have a bad price to report to us
