swift flight so that we could get off of the plane quicker.

getting in and out of the seat was awful. especially when the seat in front is reclined. the armrest on the aisle seat should be able to move up as the others in the row did. the metal underneath the armrest is pretty sharp and jagged, scraped my palm as i was trying to get the seatbelt to buckle.

Loved crews.

Our plane was delayed for 5 hrs. On top of it, they brought in a smaller plane with 100+ less seating than original one which caused us losing our reserved seating. They refused to give us our seating arrangements up until the boarding time. All the other passengers had boarding tickets but us. So our family couldn’t sit together. I had a super pleasant experience with Air Canada prior to this trip so it made me so sad. On the other hand, crew were fantastic. We missed our connecting flight but they took care of us so I was happy in that sense.

Friendly crew.

Terrible food and entertainment on the flight to and from Santiago. Felt squizzed like a sardine in the can in the middle row. I will never choose Boening 777 for overnight flights. Transfer in Toronto was confusing. Delayed arrival caused problems in retrieving luggage and made a stressful experience getting to Chicago flight on time - not mentioning sluggish US border check in Toronto. For my next trip, I would rather pick another airline and transfer airport.

Latam screwed my son in law, pregnant daughter, and 2 year old grandson. Due to a delayed Latam flight, they missed all international connections. They were stuck in Santiago for 4 days with no help from Latam. Their bags were lost by the airline. NOBODY behind the counters took responsibility to help get them home!! Their passports, credit cards and money were all stolen during this 4 day period.

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.
