I had two retro credits that were overdue for posting. They were for different travelers. So I ran a little science experiment yesterday. For the smaller missing credit for an account I manage (and where it doesn’t matter for status, just a potential future award) I followed up via email. For a larger (DE J) credit for myself I called it. The agent confirmed on the call that the credit was overdue and that they would manually credit it instead of following up again with DE, but that it would require a supervisor override. He promised to send a msg and that it would taken care of by early next week.

Today I received emails for both retro issues and the miles had posted correctly.
