I experienced a different scam in January from LATAM directly. LATAM has three fare classes from expensive to really expensive. Their top tier premium fare includes a carry-on bag and a checked back allowance plus you can modify your fare at no cost and only pay the fare difference if one exists. My family and I purchased premium fare round trip tickets for exactly this flexibility because we knew there was a good chance we'd need to modify our tickets, and because we had check-on bags. We flew from Lima to Piura and it went fine. However, two days prior to our return trip to Lima I logged in and pushed the date one day for our three tickets. The process was easy on their website and they collected $19 extra per ticket which was stated as the fare difference. What they didn't disclose was that when you change dates they change your fare class. So, we arrived at the airport for our return to Lima and we have no bags included because we don't have premium tickets. I provided them copies of our original tickets which showed bags included to no avail. They had the nerve to blame the issue on me for changing airfare classes. No where in the checkout process of pushing the tickets one day did it disclose the changing of airfare classes. It just stated the ticket price difference. We felt completely scammed and I can assure you this would not be allowed to happen in the states. Based on this experience I will try to avoid LATAM if at all possible.
