Speaking of airpasses... looks like LanChile has a new one for South America which looks like it is cheaper than the oneworld airpass:

I'll be arriving in Lima on LanPeru but leaving on American on an award ticket. Anyone know if the airpasses are valid with award itineraries? Also looks like the Visit Chile airpass is good to Easter Island, which it hasn't been previously.
