Delta American Express 40,000 mile offer
Received an email today from Northwest/Delta now offering 40,000 miles plus two one day Sky Club passes for getting their American Express card. You get 25,000 miles right away and then another 15,000 miles after spending $1,000 in three months. They also make a point to say that your Worldperks Visa will no longer earn miles. I think they are getting desperate and finding out that not as many Worldperks Visa holders are switching to American Express.
