Cons: Food isn't the best (had Hindu meal for my flights) not sure if there is a better option. There isn't much in terms of snacks, outside the set meals. Some of the crew members do struggle with communicating in English, but I always found someone to work with.

Pros: I was rerouted entirely to fly with Austrian Air, and only landed 2 hours later than scheduled, which was nice.

Cons: My Gulf Air flight from Bangkok to Paris was delayed 7 hours which would make me miss my connection to Paris in Bahrain...and they wanted to put me on a new flight that would have me layover in Bahrain for more than 18 hours, and landing in Paris 24 hours later than planned. I politely said no and asked them to find me something else, and they did--so that was good. But the suggested alternative for a 7 hour delay was absolutely ridiculous. Also, the 7 hour delay was never explained and no other flights were delayed, so I guess it was something wrong with the plane?

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: We paid $37 to check in 1 Baggage and the flight from SFO to Beijing had delivered the baggage in baggage claim area. We had to take Chinese Visa to get to the baggage, even-though it is a transit. We missed the next connecting flight to Shenzhen as it ate up all our time. Now have to travel in the mercy of the airlines for next flight. PLEASE MAKE SURE YOU LIST THAT "VISA NEEDED IF CHECKING IN BAGGAGE"

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,
