I just checked on cheaptickets.com. On the payment confirmation page, you have to find the small text at the bottom that says "You agree to the fare rules and restrictions applicable for this fare" and click on the link to see the fare basis. The fare code is VHP4US.

It looks like delta.com is having trouble finding the SVO-CDG leg (which is marketed by AF). I would call Delta to see if they can book this specific itinerary using the VHP4US fare basis.

EDITED: Didn't see that you've already booked the flights. I would call Delta to confirm that you'll get full MQM credit. The fare class is not enough to guarantee -- all consolidator fares show up as normal fare classes; they are distinguished only by their fare basis codes (and prices of course).
