I booked a DFW to Georgetown Guyana ticket about 2 weeks ago for 24,000 miles round trip in February where the cash price was around $1,200. Last February I got a DFW to Paramaribo Suriname ticket for 20,000 round trip where the cash price was around $1,100. (AA has since discontinued service there). In December I booked a one way EZE-JFK-DFW in Business for 50,000 miles where the cash price was about $4,500 (I believe the nonstop EZE-DFW in Business for the same date was 350,000 miles).
