We booked american because it was a direct flight. No explanation was given for the switch. Then we almost missed our connection because we sat on the tarmak in Barcelona for an hour. Again no explanation . Very stressful and irritating.

Having the flight switched from a direct to transferring in Madrid.

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.

When our flight was delayed in Denver the agent at the check in gate worked very hard to get our flight plans changed with as little impact as possible.

We understand that delays happen but due to a delay on American Airlines we have lost our luggage and it doesn't seem likely it will be returned. We had five pieces of luggage lost during our flight from the U.S. to Spain. When we arrived in Madrid we were told that all five pieces had been located. When we went to pick them up the next day there were only four pieces at the airport. We were told the fifth suitcase would be delivered when it was located. It's ten days later and there's no sign of the luggage. It has taken multiple phone calls to get the information about the luggage correct. They assure me that they have everything correctly documented and then when I call back they haven't changed a thing. It has been a very frustrating process overall.

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,
