| New York to Porto Alegre via Sao Paolo. I have no complaints for the service on the plane, but I will never fly with LATAM again. The customer service with the airline at the airport is horrible and you'll find yourself pulling teeth trying to figure out what exactly is going on. Everybody gives you a different answer for questions you have regarding your flights and it's extremely frustrating trying to deal with those who work for the airline (again, not as flight attendants but airport workers). On the way to Porto Alegre from JFK, I had a connecting flight in Sao Paolo. Since it was international to domestic, we had to pick up our bags and transfer them to the correct terminal. My sister checked her bag in and never saw it again since the woman working there sent it to a completely different city in Brazil. The entire time, my sister received no word on her bag and it wasn't until we got back to JFK in NY that we realized they found the bag in Sao Paolo (since it got sent back). This didn't matter though since when we got to JFK, 4 more bags were missing and we had no idea where they were. We were traveling with nine checked in bags and only received five when we got back to New York. Two of the bags missing were mine and I went home with absolutely no clothes, shoes, or gifts. After traveling 14 hours, this was rather frustrating and the response from LATAM employees at the airport was even more frustrating. They said how they didn't know how it happened and that sometimes security kept the bags extra to check them before sending them on the plane. I didn't think this made sense since five of the nine bags had been sent. They told us they'd "try their best" to find them and to keep our phones nearby just in case they found them on the next flight. It was just ridiculous that not one, but 5 bags had been lost during our experience with LATAM. Needless to say, this was the last time I would be flying with LATAM and I will makes sure to look into any other airline I use before flying with them.
