Stuffy on the plane. This might not be the airline’s problem but it was hot and the air vent didn’t cool me down.

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.

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!

The boarding went quickly and was well organized

That the price to take a small carryon was just as expensive as taking a large suitcase, ended up having to pay and extra $80 r/t for a small bag and I just that's standard for them. There were no barf bags in any seats, believe me everyone around us was looking as the person next to me was getting sick on the landing because it was crazy rough. When we finally were able to get an attendant over she was as rude as could be, I'm sure this sick person next to me was sorry she "inconvenienced" the crew member, if they just put bags in the seats pockets like every other airline this wouldn't have been an issue. The seats were very uncomfortable with no padding and not able to tilt. The tray tables were nonfunctional, too small and did not extend to get anywhere close enough to reach you. The plane ride itself felt like we were on a old school bus on a gravel road. I had a round trip ticket with frontier and both trips were equally as bad. I will never travel with them again, Most of us weren't even sure if we were going to survive take off with out the plan breaking or something.

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.
