We did not crash. Eventually we got to our destination.

All flights were awful. None were on time. I paid for economy plus aisle seat but was put in economy middle seat anyway. Asked for refund and was sent to 3 different people. The final person, a gate agent for my departing gate, Peggy Hunter, told me that she has 35 years experience and she knows everything about United Airlines’ processes. Told me the only way I might get a refund is to submit online but that paying extra for a seat upgrade doesn’t mean I will actually get one and that I should read the fine print on the ticket. Had previously spoken to another gate agent who had told me that I could ask for a refund at the departing gate. Wifi didn’t work. On one of three delayed flights had to beg for water to take my medicine. I will make extra efforts to avoid using this mediocre airline.

Free movies, and crew were helpful once we were in the air

Gate agent did not start forcing check in, which caused delay in boarding. Ground crew did not stock aircraft until 20 minutes after scheduled departure time. and DFW did the usual 20 minute taxi and then 15 minute hold prior to take off.

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!

Crew were very nice.

Poor food for vegetarians. Also the overhead space was not locked properly. Suddenly, it opened and my carry on fell out. Luckily, it didn’t hit my husband who had the aisle seat or anyone else. However, I am upset because my laptop was inside this and may be damaged now.

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.
