Panam Clipper: Thanks for that information. I have copied it and forwarded it to my daughter. In the past I have been given advice from this site about which lines move more quickly (in Toronto the far left line is for crew and as soon as they are done, they open the line to everyone so if you are in the next closest line, you can quickly shift over and get thru faster) and hoped to find out something similar for this airport.
Stealthmidget: It is my understanding that international transiting passengers in SCL will not have to pay the reciprocity fee.
