The food is very tasty, but AA has not changed the menu in at least one year.

Plane was old and dirty, seat pocket had junk in it. Seat was broken and couldn’t stay up. In flight movies were from few years back with a center tv and no head rest screen. Crew on overseas flights tend to be older in age and less tolerant..much better on continental on the same route.

The only decent point was the food. Not great but at least edible.

Since check in in São Paulo was a complete chaos. There were only 2 people helping on check in (in machines) and these people were still not helping people (like me) with questions about on how to do check in in those machines. On the other hand to dispatch the bags there were almost 8 attendants to receive the bags. Ridiculous! I’ve tried calling American Airlines and Latam several times to assign a seat for me and they swore there were only middle seats but I know how airlines work to make extra money on these seats. At the end, they only gave me a middle seat option and I had to take I.t of course. On the plane I realized there were dozens of empty seats and yet they made sure not give them to me or anyone else. Unbelievable! Unfortunately I still have to use AA on my way back to Brazil. After this, I’ll chose another airlines for sure. Also, the 3,4,3 arrangement is ridiculous: there’s no corridor space making people touching you everything someone passes by your seat. And boy! Those seats are so uncomfortable and there’s no way to incline the chair so you can even have a little rest (because it’s impossible to even sleep on those seats). The crew were simply doing their jobs! No pleasure! No smile! No engaging with anyone unfortunately! They looked miserable and I asked for water and the flight attendant NEVER brought me anything. Seriously! Water is free!

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.
