Thinking out aloud...
I have the opportunity to cross 125 K miles this year on Delta and become a Diamond elite flyer. But other than getting a few more (eventually unusable) upgrade coupons and other less- consequential 'rewards' there isn't any value in becoming Diamond elite. So, I am considering not crossing the 125 K... instead fly up to may be 120 K, and then use the rollover scheme to start 2010 with 45 K medallion miles.
Can you poke holes at my thinking? Is there anything I am missing? Is there any real value in being among the first batch of Diamond flyers?
Thanks a lot!
