AV has made a mess of its routing rules and now allows you to fly JFK-UIO as JFK-BOG-LIM-UIO, with unlimited stopover so you can make LIM the true destination instead. GF into any OTA because AV website will not offer you this lucrative routing.

You can also fly it as JFK-BOG-LIM-UIO and back with UIO as the "correct destination" for a few dollars more in taxes and earn more miles-- for this suggest ITAMatrix into BookWithMatrix.
