Although my TSA Pre check number was on my flight coming into Atlanta, it wss not on my fight leaving Atlanta. That caused me to arrive at my gate 5 mins before boarding time and prevented me from having time to eat breakfast before my flight.

Great pilot..

Jam packed too small and the lady flight attendant was to bossy and not that welcoming, she was more interested in being more of a drill sergeant than the comfort of the passengers

It was a very good fight

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.

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.
