DP: I had to call in, but I was able to get credit for my late December 2023 premium class charges. They did not code automatically.
There was a bit of a back and forth with the agent that yes, this is for 2023 and that no, I did not hit the $200 limit there (since I changed my airline for 2024 and have already max'ed out the credit). But they did issue the credits after all of that.
