Reply To: Who knows how much 20,000 united miles is worth in cash.

I would think not much, since it normally takes a minimum of 25K miles to get a free ticket. So figure 25k miles is worth about $400. But if you sell the miles to somebody dollar for dollar, they might as well just buy a ticket (with less restrictions). So figure even 25k miles is worth only 50-75% of that $400 amount. Did that make any sense?
