What about the15K CO award on CM for travel withing Central America, Viajero?
I used that one last month... as an open jaw with a SJO stopover (GUA-SJO//-PTY-SJO) and have always considered it to be a great value since intra Central America fares are so high.</font>
Think Central America fares are high?? South America fares are higher!
Try this on for size: lowest excursion fares between San Juan and Santiago is $1076 round trip on any airline!! Any open jaw/stopover would be icing on the cake.
How is this useful?? My mom

:
She'll soon have a free ATA ticket she can use MSP-SJU. I can easily find a cheap ~$200 East Coast-SJU ticket and we meet there. Then we can take COPA together down to SCL.
So comparing the 15K wth the 20K awards, the 20K potentially saves you quite a bit more, for a relatively small increase in number of miles required.
