The flight actually left.

Poor communication. Flight originally at 11:35, then 12:05, then 12:15... At 11:55, they said they would start boarding in 20 min. How can you do that and still take off at 12:15? Answer: you can't. Just be honest and keep us informed. Bonus: United sent me an email saying that connection had already left (it hadn't - thanks United! - awesome service as always!)

Flight was cancelled on our way back home from Gudalajara, was speaking to a representative for almost 2 hours to get me on the next flight the flight representative forgot to put me on hold and told everyone how rude i was, i was not rude i was just trying to get home. The representative couldn’t help me so i asked to be transferred to a manager, after 2 hours i was transferred and the manager hung the phone up. Long story short i called back spoke to another manager Yana and she was the rudest lady ever! She basically told me for waiting to long i will have to be placed on a flight 2 days after my cancellation flight. I started to cry because i needed to be home and she basically did not care so i took the date. Never again and i will warn everyone about this airline and their customer service!

I found the reason for being late to be questionable They said heavy snow but as i flew in i looked out the window and saw all roads nicely cleared That does not happen in 3 hours

They did not get my liggage to the connecting flight And here i am in Ukraine with no winter clothes at 7 below 3 days later

Improper handling of situation. There was flight scheduled later, but CS agent kept jerking us around. By the time I reached the United counter, the next flight was full. My total flight time was 36 hours. I still can’t believe that the pilot was missing. Worse yet, the agent at the gate could have made things much easier instead of telling everyone that a pilot was on his way to the airport.

Nothing!. My brother and I got to the Airport 45 mins before the Check In Counter Closed but we didn't make it Thedue to the fact that we had a flat tire unexpectedly so my flight was cancelled and rescheduled to January 10, 2018 and paid extra $480.00 including penalty. If the Check in Counter did not close early, I could still be able to check in on time while there was still 45 mins remaining.

cheap ticket will put you in seats that are in the very end of the plane where you will feel most of the turbulence.

you will be the first to go inside and come out last. food is not impressive at sll!

Super nice service from the crew on the flight. And the young woman at the check-in counter in San Francisco was terrifically friendly and helpful.

Flight was just slightly delayed leaving in both San Francisco and Taipei. But the headwinds (certainly no fault of China Airlines!) made us 45 minutes late in Taipei, making us a little anxious about making connections, especially when we saw the long line to x-ray baggage going from one terminal to the next.

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.
