Never knew flying domestically with a company named American would be so impossible. A true joke. Never had such difficulties traveling about. Super unsatisfiee and will not be traveling with them again. I urge everyone considering to purchase other airlines as well.

Not much.

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.

The seats actually had individual screens, which was a very nice surprise. There’s a decent movie collection. alao the flight attendants were very nice and friendly.

The tv show selection is quite poor. Also, like the previous flight, my husband and I weren’t seated together (not even in the same row) and when I tried to change it online, the entire flight showed as booked. However once on board there were clearly a number of empty seats.

No snacks on flight. The charging stations come in between legs space and very uncomfortable they got to be re adjusted. Make sure these are taken care in upcoming flights.

The snacks and meals were decent, as far as plane food goes (although the “vegetables” with the chicken were pretty awful). Also the entertainment selection had a wide assortment of movies, but disappointing tv show selection.

The boarding process was a mess. Just a huddle of people, with no clear direction and no one enforcing lines or boarding groups. Also my husband and I weren’t seated together and when I tried to change it online, the entire flight showed as booked. However once on board there were clearly a number of empty seats.

We had a newer plane. I LOVED that the seatbelts had a little more room, and also that each seat had it down screen. I really enjoyed the new pre-flight video; it was entertaining and I appreciated that it allowed the crew to get ready, rather than demonstrate a seatbelt for us.

I am not sure how boarding groups work, but I will never understand why we don't board from the back of the plane to the front. People waiting and trying to load luggage or climb over others makes the pre-flight more stressful than it needs to be. (This is obviously not specific to you airline.)

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.

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.
