I was charged $130 to check my baggage from Santiago Chile to New York. It was only one baggage checked and it wasn’t fully the standard size. And then to get hit with $130 was to me not favorable to the airlines. Because on most international travel, they allow one bag to be checked in. So in the future, I would have to think twice about booking Latam again other than that it’s a very good airline.
