Haven't seen this mentioned anywhere on flyertalk. Only up till the end of December.

Intercontinental Flight in Economy Class 10,000 additional kilometers
Flight within South America or Europe 5,000 additional kilometers
Flight within Chile, Peru or Argentina 2,000 additional kilometers

Worth it for an intercontinental flight, as 20,000 points is enough for a flight within a zone in Chile.

Free 5,000 points for signing up to LAN too...

Has anyone here flown LAN before? Is this offer any good?
