Did a search and couldn't find the answer. Just booked a cash and miles ticket; miles on the outbound, cash on the return, with my Delta SM number in the reservation.

My question is; Will I receive miles & MQM on the return flights I paid cash for? NWA.com seems to indicate that you do, but I'm unsure if that is only with my NWA number or if Delta will credit this as a paid ticket. Anyone run into this situation yet? Any help would be appreciated.

Thanks
