We were not allowed to carry a bottle of water onto the 8 hour flight.

There was a mechanical issue with the plane that they had to work on before we could take off. That's fine, by all means, PLEASE make sure the mechanics are functioning properly. What was a problem was the fact that we sat on the tarmac for 4.5 hours without moving, without letting us off the plane, and without climate control and air running through the plane. There was no explanation as to what was going on; they just kept promising that it would be "15 minutes, then we are on our way." At one point, they even switched the entire crew out and told everyone we just needed to wait for new employees to show up. Then, as the 4 hours were not moving, an hour before the full refund, they made a big show about "the flight starting and the doors are locked, so you have to sit down." We didn't move for another 40 minutes; they were just trying to skirt around legalities that entitled us to restitution. When the flight finally was underway, the plane was gigantic but cramped in design, my entertainment screen kept freezing and glitching, and subtitles didn't work, and the crew was passive-aggressive. Terrible flight.

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

Good flight, boarding ok and crew very nice. Flight was not full so I was able to be very comfortable. Blanket and pillow provided with was good as it was very cold during the flight . Food was very good(small snack sandwich and an excellent piece of orange cake). Overall good flight, no complaints.

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

Poor, the airline was not able to help me move flights.

Check in -- in business took over 30 mins as there was only one attendant. Boarding was also a mess. The seat was too narrow and was not working properly. Food was very bad and the entertainment very poor. Crew was very polite and helpful, in fairness.

The way the Pilot made all announcements, specially the way he congratulated the entire crew as the best team ever, making a comment that due to them they were able to shorter the delay to the destination. Amazing flight .

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.
