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.
I would check the IAD-LIM route on LAN. Back in May when I was booking Machu Picchu tickets, that route often had 7 saver seats in J on the days it operates (it doesn't operate every day). The other route to look at is MEX-LIM, but that will require going through customs in MEX (so a little bit of a hassle).
