The crew was friendly and informative. They were very helpful. The

The seats were uncomfortable. They were hard and so narrow I had to sit crooked in the seat to keep from getting banged into by the service carts and every person going by to the bathrooms. I'm not tiny, but I'm not huge either, it was just overcrowded. It was also very hot in the airplane the entire way from Phoenix to Spokane. My husband, who is always cold, was even hot.

Three hours delay. I paid for a upgrade to first class. But because of the flight change i didn't get to keep my upgrade and I had to beg for a refund. I have had two trips in the past 5 days and all flights have been anywhere from 1 to 3 hours late. Worst experience with AA I have had in a long time.

My wife is hypoglycemic and requires food. The flight was so early that none of the terminal restaraunts were open, nor did the plain have food for any passengers accept first class. I've purchased a box on other flights, but this one did not provide an option for a box lunch or breakfast.

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.
