I hesitate to tell you what I recently paid for a trip to South America...but I will.
We booked a trip to Patagonia. There is no way I am flying in economy so I wanted to book Business. The business cabin was nearly full on the dates I needed (including dates nearby). So I booked what I needed. The trip was PHL-MIA-SCL and EZE-DFW-PHL. The cost was 245K miles per person all in business/first. I know you all think that is crazy but I have tons of miles and I needed those flights. Furthermore, the cash price was just as outrageous.
