I call in advance to paid the fees for baggage, I call Aeromexico because was the main airline for the fly, but Delta at Seattle made me paid again the fees for baggage’s even by phone they said that I didn’t need to paid. BE AWARE AND CAREFUL BECAUSE THE LADIES IN THE FRONT DESK didn’t even look the paperwork that you have in hand, they only want to charge you saying that your payment thru Aeromexico didn’t help you in the 1st fly. How this can happen when Delta and Aeromexico are two subsidiary one of another ?

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.

The flight crew was excellent. They spoke Portuguese and English and was really friendly. Fernanda was always smiles whenever you saw her, she was really nice.

The boarding process seems a little off because everyone rushes to make the lines and then when you get on the plane, there's a wait to get to your seat and hope there's overhead room for your bag. I know they is not the airlines problem and it's with every airline, I'm just stating what I did not like. The crew made it as tasteful as possible and did keep the lines moving. This crew for this flight was wonderful.

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,
