I've had about a half dozen partner segments this year (AZ, AF, KL), all booked on 006 stock and purchased while logged into Delta.com, so my Skymiles number is in the reservation from the beginning. Every time I've waited 10 or 12 days, but the segment doesn't post. I then file a request for credit and I'm quickly credited. Each time their template response says that "at the time of your next reservation, you can expedite the posting of your mileage by providing your Sky Miles number to the airline representative." That sounds like an attempt to blame me for the miles/mqm's not posting. However, with every flight I've confirmed with the gate agent that my number is listed, and I've checked the boarding pass to ensure the number is shown there. Am I the only one seeing this, or is it wide spread? Have you personally experienced it? I'm thinking this is a deliberate policy, to not credit the miles/MQM's unless the customer notices and asks. By so doing DL can save millions of miles, at no expense other than violating customer trust and not keeping their word. There is a lot I love and respect about Delta, but that doesn't include how they manage Skymiles. It gives them a big black eye.
