What airlines would be the cheapest in points from NYC to Patagonia (PUQ)? I saw on another site that it is 50k miles via Mileage Plan/Alaska Airlines via LAN. I called LAN and they told me it was over 200k miles to make the trip. Wondering if I am doing something wrong, or if anyone else has any suggestions. I have visited multiple sites that give prices of awards but still unsure my cheapest option...

Would be leaving on the 23rd of December and leaving on either Jan 1 or 2
Thanks!
