The crew was nice

I flew American four times in 7 days, every flight was delayed. delay times varied from 90 minutes to over three hours. Fog in Chicago was beyond anybody's control, but the other times were not weather related, I recently flew frontier Air and their flights were also late. I jinxed myself by stating I never have this issue with AA. Great job at proving me wrong. I flew a good bit last year and these issues didn't start until after the new year., Thank you for your time.

Tight connection! The airlines need to Realize that a 2 hour layover is NOT enough when you have to go through immigration, customs, and security before making your next flight!

None of the experience was pleasant

First flight was delayed causing us to miss the 2nd flight and we ended sleeping on a chair at the airport waiting for a morning flight. AMERICAN AIRLINES didn't even have the decency to put us in a hotel for the night due to their delay. Then they added a 2nd lay over which was delayed for hours also. Traveling was to visit my mother who had cancer and I was sick so this made the trip even more distasteful.

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.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days. Fares are subject to change and may not be available on all flights or dates of travel. Some carriers charge additional fees for extra checked bags. Please check the carriers' sites.
