Nothing good to say about AA

AA screwed up reservations by rescheduling flights by 3 hours earlier (done not once but two times) causing 6 hour layover. This plus an additional 2:38 delay on next flight made the journey horrible. Will never book an AA/BA flight again for intrnational travel.

The crew was pleasant and it was nice to have a complimentary meal and wine. We landed very early.

This plane has not been updated since before I was born. The seats were extremely uncomfortable and there was no in seat entertainment, just overhead screens. I was never able to get the WiFi to work. There were no power outlets, and we were never offered headphones, eye masks or ear plugs. I expected more from American since our 2hr flight from Orlando to JFK had working WiFi, power outlets and in-seat video monitors.

The crew on The flight was efficient and friendly.

The flight was so crammed. I understand there's the possibility of flying on a fully booked flight but if it took an hour to load the passengers how quickly can you realistically get 400 passengers out? Plus it prevents everyone from having an overhead cubby. You need to reconfigure the flying experiwnce.

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.
