This thread was somewhat helpful (and depressing) going to Machu Pichu from Montana. Going down 0 business saver on AA- ever. I called and said LAN goes a lot form LA but found out LAN releases maybe 1 business saver per month which was less than helpful on an anniversary trip. So we booked an economy which includes a long layover in Dallas and a dreaded 9 hour flight to Lima which every seat guru comment was bad. In fairness to American we found business saver back but only from Quito and only if you searched every day using the 331 day guide. Seats would pop up and be gone within 24 hours- it is possible but quite time consuming and includes a nasty Miami layover.
