Delta SkyBonus, the company incentive program run by Delta, is offering a good bonus when you join, book and take at least one flight within the next 60 days.
Travel on Air France, Alitalia and KLM is eligible too from what I understand. While not mentioned, I suspect the flight should at least earn miles to be credited to Delta.
While the promotion is targeted, many similar promotions have been accessible in the past by non-targeted members. So it's worth a try and 7,500 miles is a pretty good bounty for one short flight.
