Double Delta MQM

The Delta Air Lines blog just posted this promo:

I’ll also let you be the first to learn about another special promotion we’re launching. This is the first time we’ve ever done one like this, and it’s only available at delta.com. SkyMiles members will earn twice as many Medallion Qualification Miles when they book a flight at delta.com between April 1st and 30th and travel by June 30, 2008.

Registration is required.
