This seems like an old plane. Poor quality of screen to watch movies and very small selection of movies. No charging spot to plug and charge our phones. This was a long trip and these two elements are important to make the trip enjoyable.

British Airways overbooked this flight and made it unclear if I can board my flight. Overbooking is such a greedy behavior and airlines should refrain from engaging in this dubious policy. It is the second time this happens to me with BA.

My United connecting flight was delayed. I rushed to arrive at the gate prior to the departure time to be told the plane had left early and I had been rescheduled to the next morning at 7am. However, there were no vouchers available for me to stay in a hotel or get food. So, I was able to get a flight on American that got me home the same night. By the way, the American flight was delaying takeoff to wait for passengers who had been delayed on their connecting flights.

Almost everything. Only the food was lacking. I like their new planes. The outlet at the seat in coach. The magazine options at the seat as well. I did not look at the entertainment so I will not rate that. The crew was professional.

Just the food options. Ginger snaps was what was served for food and a beverage. I suppose this is what obtains on most airlines these days but can't I hope for something more like maybe a sandwich? AA has the opportunity to set themselves apart in this area.

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,
