In my experience, Delta responds to status match requests BADLY.

First, they are sticklers for detail and rationale explanations. Of the math requests I have tracked, they have completely rejected more than they have granted, and for some of the most bizarre excuses.

Second, they usually offer Challenges, and respond, positively or negatively, by SNAIL MAIL. And it sometimes takes weeks for them to get the envelope dropped into the mail.

It ain't pleasant! If you are lucky enought to get an actual match, the fastest way you will find out is by looking at your status on the website each day. But remember, the snail mail takes a LONG time! (2-6 weeks).
