Delta is running a domestic economy (and extra legroom seating) award sale. At least they tell us it’s a sale, which means there are regular prices, even though Delta hides what those regular prices are (“an ignorant customer is their best customer”).
At the upper end of value, Chicago Midway – Atlanta is on sale for 5000 miles (and tax of $5.60). That’s better than paying 12,500 miles of course for the same flight. And its actually a good deal. Normally when we see these sales 5000 mile awards correspond to flights less than $90. This time 5000 miles can save you nearly $200.
