Have a friend paying cash to fly NYC to Santiago Chile 8/12 - 8/22 and LAN has it for a really low price of ~845. He's adding flights to IPC (Easter Island) 8/16-8/20 and it's only another ~$20. I don't know how many other dates worked but both the RT to Santiago and the add-on seemed like good deals.
Related question, does anyone know what the options are for rebooking/refunding a dropped LAN fare?
