After our experience with Peruvian Airlines, LATAM was a welcome experience. The check-in process was easy and the flight took off on time. The only thing I did not like was the boarding pattern of having people with "no hand luggage" board first. As I looked at the people in the "no hand luggage" line, many of them had backpacks that were bigger than our luggage. We were the first people "with hand luggage" to board. Imagine our surprise when a lot of the overhead storage was already taken by the people who supposedly had "no hand luggage". Something definitely needs to be fixed here - but overall a good experience.
