LATAM’s crews are fine, but God help you if you need any customer service. Their app and website never work, with error after error. Trying to solve anything over the phone is painful, and lastly, the boarding pass LATAM gave me to board the flight with Delta was invalid and I had to purchase an emergency one-way ticket at the last minute to get home.

LATAM’s crews are fine, but God help you if you need any customer service. Their app and website never work, with error after error. Trying to solve anything over the phone is painful, and lastly, the boarding pass LATAM gave me to board the flight with Delta was invalid and I had to purchase an emergency one-way ticket at the last minute to get home.

We traveled with two young children, and it was not possible for our family to be seated together. No one offered help or assistance to organize seating so we could sit with our kids. In the end, we managed to find two seats in Economy so I could at least sit with one of them, even though I had originally paid for Comfort+. In summary, I had to downgrade my seat just to be able to sit with one of my children, which was very disappointing

I booked a flight through Kayak to Brazil I have traveled to Brazil several times before Kayak Delta or LATAM never mentioned during the booking or in the pre flight process that the visa requirements to visit Brazil have changed earlier this year. I was unaware of this change and as such never got a visa and was unable to fly from JFK to Sao Paulo Add to this that Delta allowed me to fly from Boston to JFK which they should not have as I didn’t have a visa. It has been a terrible experience and a huge loss of money

Latam may be the worst airline in the world, far worse than even the lowest of low cost airlines in the USA. I wasted hours trying to PAY THEM TO CHECK A BAG! Then they misled me at the terminal, sent me through the wrong security line, the list goes on and on... Just absolutely terrible in every way. Avoid at all costs.

The flight was late. Please do not delay next time.

I couldn't travel, now I can't get a refund and to change the date I have to pay an absurd fine.

My biggest complaint is the comfort. I am not tall and there was no legroom. It was very uncomfortable. During my transfer in Sao Paola, the flight was slightly delayed so boarding was confusing because there were no instructions in English.

I never got this flight. You sent me to Chile!!! And from Chile I got the other flight to São Paulo... I've arrived 7h latter than I was supposed to arrive because of Delta delays.

Because the flight was late, we lost the connection to Brazil. You, Delta delayed, and you Delta anticipated the door closing in 15 min from Miami to GRU. Why? It caused a lot of stress! I almost could not see my mother in law alive because of your delay.

My entertainment did not work. I was very tired from the botched connection, and the poor sleep
