Book a LAN South American Airpass (LAN.com) for an easy, money-saving way to hop 'round south. Covering over 50 destinations, the booking widget creates D.I.Y. circuits at a discount of what traditional one-ways would be. New routes—Lima to Easter Island (from February 2012), Lima to Igauçú Falls (Brazil side), or Guayaquil, Ecuador to San Cristobal in the Galapagos—make traveling direct from the U.S. a cinch. A main hub in Santiago connects through to all of Central and South America.
