In an effort to aid those who were affected by the May 12 earthquake in China, Northwest Airlines is asking customers to donate WorldPerks miles to The Salvation Army – which is "actively participating in the disaster relief efforts to help survivors who are suffering from the loss of their homes, belongings and loved ones" – and plans to match donations up to one million miles.

From Northwest's WorldPerks Terms of Service: "Award travel has no cash value and will not be refunded."

Way to pitch in, guys.
