Agreed . . . . I can only find flights of $1300+ RT from Sacramento at this time.

When I check LAX-EZE on http://matrix.itasoftware.com, with one date in January and one in July, Continental offers the lowest fare of $1,090 RT including all taxes. All other airlines are at least $300 higher (and more like $360 or more higher for a one-stop flight like Continental's -- change in Houston).
