DL.com will sometimes recognize that you flew but there's still a lag until your miles post, especially on weekends. Back in January I flew on a Friday RDU-DTW-LAN. On Saturday, the flights showed on DL.com as posted but with 0 miles per flight. On Sunday, the proper mileage amounts had posted. Just be patient.
