There was a change in our flight. According to Delta you didn't confirm every leg of our flight and the plane was over booked.

The most horrible experience. Pathetic to say the least. No water in the flight lavotries. Such a pathetic service from so called top airline.

Long wait for de-Icing. Got on and off the plane 3 times. First wait was 1 hour, but plane aborted takeoff. Second plane waited at gate with all aboard for 2-1/2 hours and never got slot and de-planed. Third plane waited 1-1/2 hours for de-Icing and finally we were headed home. Arrived 8.5 hours after schedule.

We had the best flight attendant ever! Her name was Sharon on Eandeavor / Delta Cnx, and she made the experience the best flight I've experienced. Thanks Sharon for being awesome!

Nothing. From the plane to the awful delay and poor service.

Lack of communication. Old plane, no comfort and 6 HOURS DELAYED. Truly disappointed by the airline

Free movies, and crew were helpful once we were in the air

Gate agent did not start forcing check in, which caused delay in boarding. Ground crew did not stock aircraft until 20 minutes after scheduled departure time. and DFW did the usual 20 minute taxi and then 15 minute hold prior to take off.

Easy and efficient boarding for a busy flight. Efficient, attentive and intuitive cabin crew. Good in-flight entertainment and facilities.

The aircraft was extremely cold throughout the duration of the flight. Of all of the long haul airlines I've flown with, I find that American Airlines offers the least leg room.

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.
