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!

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!)

I had only 40 minutes to get to my connecting flight. Then the plane was 15 minutes late. They wouldn't switch me to a seat that was open closer to front of plane and my bag was lost w important things in it that I need for this evenings show. I'm a full time musician.

I’m starting to think that Alaska Airlines is the last remaining U.S. airline whose business policy seems to be authentically rooted in genuine good will to all people, customers, non-customers and colleagues. Or maybe it’s really always been in a class by itself. It translates to excellence throughout their organization, and, well, it most certainly doesn’t go unnoticed. Thank you for another wonderful experience, Alaska Airlines!

Book the flight with Kayak never let us pick the seat and I’m not be able to sit with my husband! That the worse next time I’ll just book directly to the Airline website.

American continues to surprise through their lack of consideration and cheapness Prefer to have seat empty on the front rather than move passengers that are loyal frequent flyers. The most important point for American is you have to pay for everything including for flight status. No longer miles flew but how much you pay them

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,
