if you have a hard engagement that you have to make, i hate to say it, but use a bigger airline. These guys are not dependable nyc -> miami. Have had 2 flights cancelled and delayed over 6 hours in the last 6 months. Only one scheduled flight everyday. If you can risk it, fine, but otherwise not worth it.

Nice flight. No issues. Flight staff was great.

Front desk check in guy in Orlando was a bit shady. Asked that we pay for our check-in bags with cash and wanted 10$ cash to put our seats together. I did not give him cash and had to ask for a reciept for the checked bags. We were 4 hours early for check in.

The wait time for the connection was not too long. But on the way back to the US, I almost missed my flight from Miami to Washington-DC because I didint have enough time to go though imigration and also had to wait for my luggages. Thank you!

American continues to surprise through their lack of consideration and cheapness Prefer to have seat empty on the front rather than move passengers that are loyal frequent flyers. The most important point for American is you have to pay for everything including for flight status. No longer miles flew but how much you pay them

The crew are always excellent.

The comfort is horrible. Airline companies keep shrinking the seats and charging more. Also they keep serving less food. And flight changes.

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,
