I got an interesting offer from Delta SkyMiles today.

The headline:  “Enjoy up to 100,000 bonus miles as a reward for flying more with us.”

The scoop:  Earn Gold Medallion again, and receive 25,000 bonus miles.  Take it up a notch to Platinum Medallion, and you’ll get 50,000 bonus miles.  And if you’ve got the stomach for Diamond Medallion, you get 100,000 bonus miles!!  You have to fly the required MQM’s or MQS’s by December 31, 2011, to earn the bonus miles.  This offer appears to be highly targeted, but it never hurts to check your spam filter or register just in case.
