From the responses from LAN you would think that NOBODY ever did an upgrade using kilometers. How you can buy a paid ticket that earns kilometers and then upgrade it so that it no longer earns kilometers is hard for me to comprehend. An agent told me that the earning rate should be for the booking class the trip was originally ticketed in. That makes sense. But I can't find a written policy anywhere.
