Thanks for all the information. It is interesting because LA includes PPT on its South American network. They should include PPT in South America to facilitate matters the same way they also include the Middle East in Europe.
One way out to visit PPT would be to fly 2 segments SCL-IPC-SCL (Eastern Island) and buy a separate LA ticket IPC-PPT-IPC. It is funny because the same flight makes both routes as LA operates the B767 SCL-IPC-PPT-IPC-SCL.
Thanks for the information!
