Bolivia's Aerosur will conduct charter flights from JFK

I did see yesterday that Aerosur was still using the 727. I saw it depart last evening on 22R

Saw the 727 on Sunday, too. I was waiting for the departure at Bayswater as they were using 13R all day, and it finally started its long taxi out to 13R. Then, I lost track of it, and it turned out it continued all the way around the airport back to 22R.
