Well, here's what I learned after finally speaking to someone at Delta who knows the "ropes".
My requirements will need FF miles as follows:
* MIA/ATL, 25,000 miles;
* ATL/SCL and EZE/ATL, usually 90,000 miles;
* ATL/JFK, 25,000 miles.
So, even though it's one ticket, there are three FF charges, and, the tickets I assumed we would get at 90,000 miles will each now require 140,000 miles.
The current cost of this tickey is $1813.
