Some additional information about my upcoming flights:
Avianca:
SCL-BOG-PTY - (3097 miles ) XL fare
Copa:
PTY-SCL (2974 miles) A fare
SCL-PTY-HAV (3952 miles) R fare
HAV-PTY-SCL (3952 miles) R fare
I am planning on travling Business class for the longer flights. I am not opposed to mix classes or one way fares. Just hoping I will be able to put some of these miles to use to offset the costs.
