They offer food and entertainment its good. Also is amazing to flight none stop to Mexico City

Getting to Mexico or leaving Mexico is a hassle if you are in a wheelchair. They have a really poor service, I really struggle since I was flying by myself.

Everything went very smoothly with this flight. It boarded on time. The crew were all very friendly. I enjoyed the entertainment selections and found a tv show that I had been wanting to see. I managed to watch 2 episodes and look forward to watching more of the same show on my flight back. I ended up having the 2 seats to myself which was great. Extra legroom. I have no complaints at all.

My flights were so behind I missed my connection for Toronto to Tel Aviv and was rerouted to London and then Frankfurt but the plane was late getting there as well. Air canada had no crew on the ground and over and hour wait for customer service on the phone so i had no way to find out what my reticketing status was. I was passed off to numerous other airlines and sent through the airport to the incorrect terminals in heathrow causing another missed flight. Air canada did not accept the responsibility to maintain my reservation and get me to my destination efficiently. Even when I spoke with a phone representative the person was rude and never sent confirmation of my flights so I had no reference point for flight numbers or air lines. All of his added up to more than 13 hours of delays on what was already a 24 hour trip. Worst travel experience of my life.

The plane was comfortable and the crew was great.

The boarding was ridiculous. They never posted what gate the flight went out of. If it wasn't for Kayak we would not have known when to go. The flight was delayed but they never did update that information. It did not leave on time like the board said. They just all of a sudden said they were boarding the flight.

Friendly, attentive staff. Good service. My toddler, husband and I boarded first because of our child, so we had plenty of time to get comfy on the plane. The flight attendants served sufficient drinks and snacks for the 1 hour flight.

Flight was delayed two hours so my toddler and I had significantly longer to wait, which is not too fun. However, I understand this is unavoidable sometimes.

There was a horrid family in the row in frony of me that absolutley refused to control their child at all, even when airline staff stepped in , so a really long flight was made to seem even longer and sleeping was out of the question.

Eventually able to get to my final destination

They cancelled my flight with absolutely no information to provide. No update at all. There were no agents to direct the flow of passengers stranded in the airport. Usually Airlines would rebook you on the next flight out. Apparently, this is too much for this airline to handle. Very amateur!

If you are not able to pay a Executive but still need more confort, I recommend pay more for comfort seat!

It is not Latam fault, but some customers doesn't respect the privacy and try to be in silence in a night flight...

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,
