Ok, just a bit cross-posted (for the convenience of Argentina travelers who may not usually fly LAN nor are familiar with them), but this makes for very convenient connections from "GSOT"* for those who are either traveling between SCL and BUE, for those who may (temporarily at least) want to avoid the Argentina fee, and for those who may not want to go out to EZE for any reason, and have a pleasant SCL connection for the onward flight.
