I have first class flights from LAX to ATL to BNA from November 12th that still show 0 miles. I have called and emailed Delta on this 4 times and each time they promise an update within 24-48 hours. I had 3 other flights that were also messed up (Nov. 6th, 18th and 19th) but they fixed each of those. This particular flight they cannot seem to get fixed.
I started flying Delta again in September and will reach platinum next week (if I can get my flights counted) I spoke with a supervisor who advised me to call back in once I cross the threshold and that they will validate and bump up my status regardless of whether the miles are posted once I hit the PM threshold.
