I've had the same issue when purchasing tickets from Virgin Atlantic and crediting miles to DL. For a VS operated flight, even though I entered my SM number and KTN when booking, precheck didn't show up on my boarding pass. I had to call in after check in and get them to manually add my KTN and re-check in. For a DL operated flight booked through VS, there was no precheck on my VS boarding pass, but it appeared when I re-printed the boarding pass from a DL kosk.
