Way off schedule, way to tight of space, no way to sleep being such a late flight! As far as a beverage, they were out of everything!! Nice air line for quick trips,but to fly for 4 hrs at night from leaving at 12;00am, just impossible to sleep or really relax.

Boarding was smooth and fast. The travel time was a bit faster than predicted too.

With lack of reclining seats and no complimentary snacks or drinks at all, the comfort scale is lacking. Even the tray tables were replaced by miniature, undersized, pieces. Even with the discounted prices, it’s hard to want to fly with them again.

Help that I received from check in through security to the gate was awesome. The person who checked me in offered me a wheelchair as it was a pretty long distance to the gate. I don't think that I would have made it all the way without her for thought and help! Same goes after the flight when we landed in Philadelphia. From the plane to gather my luggage and then to the place where my ride could pick me up. Awesome service. The stewards were also very helpful to keep me supplied with ice for my dogs. They get very stressed and tend to overheat. Thanks to a couple of the staff, especially, my dogs stayed very comfortable as well. Other then the fact that they got too warm a couple of times. Will definitely keep American in mind for another flight.

I have not got a background in flying. I read the literature in the seat in front of me but I would like to have known sooner that I could turn a knob to help get cool air on my dogs. They were getting very warm and I spent a great deal of time fanning them when I could have just let the air do it's job.

American can claim as many excuses as it would like, but if you can't get customers to its destination in a reasonable amount of time, you're not worth doing business with.

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. Fares are subject to change and may not be available on all flights or dates of travel. Some carriers charge additional fees for extra checked bags. Please check the carriers' sites.
