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.

The food is very tasty, but AA has not changed the menu in at least one year.

Mediocre 2.6

Plane was old and dirty, seat pocket had junk in it. Seat was broken and couldn’t stay up. In flight movies were from few years back with a center tv and no head rest screen. Crew on overseas flights tend to be older in age and less tolerant..much better on continental on the same route.

AKL
Okay 5.6

Smooth operation, on time

Seat pitch on the plane unbelievably cramped. When seats are so close that if you drop something on the floor you have to be a contortionist to get it, you know it's a problem NEVER fly the 787-900 economy.

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.
