TAM is a real disappointment. We had to jump on a crowded bus for a 6am flight - although there were at least 15 available fingers that could have been used by our plane. Then, we were placed on row 30 - the last row of the plane, despite having purchased the tickets a long time ago and being TAM gold plus members. Note: worse seats on the plane. Great way of rewarding your frequent flyers TAM ! I now remember why I stoped flying internationally with TAM and moved to American, United, Swiss, Lufthansa and BA. TAM has no respect for its customers.

They offered food. The crew passed by again offering water. I enjoyed the two seating section. I think is very comfortable instead of the three seat way, unless you seat in the middle; which it's not bad, but I wouldn't prefer. All and all, I think the lay out of the seating rows are better than other airlines so far( I haven't tried many anyways). The lay out makes the getting in and out to use the restroom less uncomfortable and cramped. First time flying with Latam. I will fly with them again

Everything was as you would expect in coach - fine. Flight was close to on time.

the flight from Boston to Curitiba was on time actually 30 minutes earlier. latam was not able to unload the luggage for custom checkup in Sao Paulo ii took two and half hours . i missed the flight to Curitiba spend the night in hotel and then flying in the morning to Curitiba

Pros: "The seat was comfort, good attention, flight on timing 😇"
Cons: "In several times the plane went down and up, and I think the pilot had no experience or it was the first time flying"
Cons: "The flight was full and all seats were taken. It means it was impossible to maintain the required and necessary social distancing."
Pros: "Muito confortável. Boarding muito rápido. Muito bem atendido a bordo."
Cons: "Infelizmente o serviço de bordo não pode ser apreciado, mas entendo que é pela segurança dos passageiros."
Pros: "The crew was great"
Cons: "They should be on time but we left 30 minutes later."
Cons: "Boarding was very confusing. The waiting area was filled with people milling around, trying to find their line."
Pros: "All the staff was great."
Cons: "I was trying to upgrade for business and the front desk told me Can only be done 24 hours. What diferentes it makes if I paid in front desk or by the phone?"
