Crap, I was too late to get this in before the Oct merger:

Elite Extra Perks 2009
The Elite Extra Perks site is currently down while we integrate the Northwest WorldPerks® and Delta SkyMiles® programs. We apologize for any inconvenience this may cause.

In October, the Elite Extra Perks program will transition to the Medallion® Threshold program. At that time, this page, and the link you received in your e-mail, will take you directly to the Medallion Threshold site.

The Elite Qualifying Mile thresholds and reward options are identical between the Elite Extra Perks and Medallion Threshold programs.

Thank you for your patience while we transition to the Delta SkyMiles program.
