Through March 31st, you can earn 1,000 miles simply for enrolling in the FedEx and Delta SkyMiles program. Additionally, you will also earn 500 miles for your first and fourth shipments after you enroll along with 3 miles for every dollar spent on eligible FedEx shipments through March 31st. After March 31st, you will receive 1 mile for every dollar spent.
Even if you will never ship via FedEx or through the online system, definitely worth creating an account just to receive the 1,000 miles. No shipment is necessary to receive these 1,000 miles. I just created an account and it took less than a minute. It will take up to 8 weeks for mileage to post.
