Just a word of caution to anyone else thinking of cashing in some miles. I wanted to book a JFK/EZE r/t. I had 197,000 miles and was told I needed another 63,000 to reach the 260,000 miles required for a biz seat. They put my reservation on hold, pending the miles purchase. So I bought another 63k and just called to lock in my reservation. Now they tell me I need yet another 37,000 miles. But I can't buy 37k, because that would exceed the 80,000/year max. So, they won't honor their original quote, won't refund my 63k purchase, and won't let me purchase what I need. The attitude was, "Hey, we made a mistake, but that's your tough luck." I guess it's time to move on. But to who-knows-where?
