It got me from point a to point b. That was the only positive thing about this flight.

Unidentified delays had me sitting in the airport for hours, seats were overwhelmingly uncomfortable, no in flight entertainment, the cabin crew kept the galley lights on so it was impossible to sleep on a late night trip, nickel and dimed over everything from a carry on bag to choosing my seat, no complimentary drinks or snacks, took forever to receive my checked bag

Airfare was $28 each way

No plug ins, hard seats, and an odd 20 minute delay to get a off the plane even though we were at the gate. They said it was because of the "balance". Really?

The seats and space are horrible, it is almost impossible to stay seated during the duration of the flight because the seats are so uncomfortable and if you are taller like I am you will have no leg room and no support past your shoulders

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.

We had to take a bus to the plane. The buses the shuttled us on, they packed tight and without apology. We then sat in our seats for over an hour on the tarmac without explanation or apologies or any courtesy shown at all to the woman who dared to get up to use the lavatory and was scorned by the crew.

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.
