Layover in Frankfurt too long; Unable to sleep on flight, nearby windows were open creating too much light, seating a bit too close to relax.

The crew was very friendly on board. The gate crew were a little curt, but it was a full flight and they were really trying to get everyone on board quickly so I can't be too upset about that.

Few entertainment options - direct TV unavailable for about half the flight, WiFi also unavailable for the same.

The overhead bin did not stay down low enough so that I could place my bag in. It would lower then before I could place my bag raise slightly by a few inches. For someone of my height (5’5”) that was problematic. Fortunately another passenger saw my dilemma and held the bin lower to its full opening capacity. This also momentarily slowed down the boarding process.

The flight was late due to maintenance and caused us to miss our connecting flight to Chicago. American Airlines customer assistance at the airport was absolutely terrible. They were rude and inconsiderate as they kept suggesting to fly standby. We shouldn't have to fly standby when it wasn't our fault why were late. They told us our bags would be ok going to Chicago and they we would make the flight, but we did not. I do not know why didn't wait for us considering there were 8 others that also missed the connecting flight. We had to fly to Denver and stay overnight with no luggage and catch a 7:00am flight to Chicago. The last surprise I received was my damaged bag when I got back to Chicago. Thank you for making this trip memorable in a terrible way. I will never book or recommend Kayak or use American Airlines again.

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.
