You don't have to fly with LAN to ship, the shipping part of LAN Cargo is separate, unless you are going to put boxes on the plan as extra baggage. The airport has a LAN Cargo shipping office to contact. You need to box up items good (strong corrugated boxes and tightly packed) and be sure there are no liquids or batteries (other dangerous chemicals). It takes a few days (3-5) to get to the destination and you pick it up at the other end. They have an online tracking system to follow the luggage. Just ship ahead so you can pick it up after you arrive, probably not going to be able to time it exactly.
