The assistance we received and the flight itself was wonderful. We will fly with LATAM airlines again, in the future.

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.

we were missing our luggage, trying to find someone to have any empathy was pretty much not happening....

The plane broke down at the Lima stopover and they offered to put me on a flight the be t day but I had to be back in LA that morning and so I had to buy another ticket from Avianca and United for $2k I asked LATAM for compensation and received none. Very bad experience

Just to drop my already labeled bag it took 50 minutes inline. Completely disappointed with Latam operation at GRU

I’m entitled to a refund per LATAM due to the mid flight itinerary change and being stuck in São Paulo for 24 hours and needing to get a hotel. The airline was dismissive and of no help.

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.
