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 flight actually left.

Poor communication. Flight originally at 11:35, then 12:05, then 12:15... At 11:55, they said they would start boarding in 20 min. How can you do that and still take off at 12:15? Answer: you can't. Just be honest and keep us informed. Bonus: United sent me an email saying that connection had already left (it hadn't - thanks United! - awesome service as always!)

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.
