Cons: "In my last connection in Santiago airport I was asked to pickup my luggage and do check-in again and all of this in a 1 hour and 20 minutes connection, when I arrived to the check-in desk at first they said that I was late and needed to be there 2 hours ago, just after argueing they let my pass"
Pros: "There was no one sitting next to me."
Cons: "Over 5 hours delayed with no explanation, no compensation and no food offered."
Pros: "The flight attendants were nice"
Cons: "The gate people were indifferent, bordering on rude. A bag which I’ve used for hundreds of flights as a carry on “weighed too much” and suddenly required checkin with a charge despite it being a carry on for the first leg. No one could explain to me the difference of the weight in the overhead versus the belly of the plane. I will NEVER fly LATAM again and will make sure that I spend a lot more than $30 for all of my future travels in their region. Too bad that their rules are designed to steal from the customer. I won’t be fooled again."
