The seats are small and too close together. I sat behind a woman who reclined her seat into my face the entire flight. I could not put my tray down to eat. Very uncomfortable.

I've always wanted to go to all five Manhattan boroughs in one day. Thanks to Delta, that happened.

The plane broke down as we were about to take off. Delta rebooked everyone on to new flights because it was pretty obvious that plane was not going to be fixed in time. The crew did their best given the situation. The situation was absolute bs though - we had to take a cab to JFK for our new flight and do the whole security thing again and all that annoying stuff. Thanks for wasting 8 hours of my life, Delta.

Comfortable seats. Good entertainment

Going to Denver was delayed and now return trip delayed We were give 3 separate reasons. Poor communication. Just telling me a flight will be delayed is not communication. Lack of a free snack was disappointing. May have to rethink flying Delta next time.

A horrible flight!!! We arrived at 5:04pm then we sat on the tamarac for 40 minutes before they could find a gate for us!!!! What a horrible lack of management!’ Who runs this airport/airline!? At the end they moved us to completly different terminal!!! Had to find a new transportation to the hotel!!! Again, what a horrible display of management skills!!

The person in Aeromexico balcony didn't have training to attend clientes in the best way. She didn't know how to add miles to my number of fidelity and she told me that she can't change my seat to the aisle, because the sistem was not working and her english was very poor too... Very poor service.

-Many errors in the menu where thing's that need to be written in Portuguese was in Spanish like salmonillo, that is a small salmon in spanish but means nothing in Portuguese. -Old plane for this route, LATAM has many new planes like the A350 and were are them? I saw many new planes that was reported to come to the Brazilian lines and we are seeing only used 767 and 777 linking Europe and US.

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,
