Best and Worst Business Class Oneworld Award Opportunities: U.S. to/from Southern South America

How the major oneworld mileage programs compare and why having the right credit card(s) makes such a HUGE difference.

This is part three of FCF’s new mileage-award comparison series, in which we grade major alliance mileage programs by how much they charge for a free award ticket in Business or First Class to various regions of the world.

In July, we focused on Star Alliance in First Class to Asia and in June oneworld in Business Class to Asia. For this installment, we examined eight oneworld airline loyalty programs to southern South America in Business Class.
