For me, it's taken anywhere from pretty immediate to overnight.

Do keep in mind that regardless of whether it's within 24 hours or not, and regardless of any fee that you might pay, Delta award tickets are not cancelable or changeable (so you can't change to some future date and then cancel) within 72 hours of the flight.
