Do you have the current AF or DL bag tag number? You can use the DL bag tracker (https://www.delta.com/us/en/baggage/...hecked-baggage or on the app) to track bags even when loaded on AF flights. You'll at least be able to see "Checked in for AFxxx" and hopefully "Loaded on AFxxxx" and have a better sense. I get that it never seems to get loaded onto the proper AF flight for security reasons (no confirmed passenger on the flight or whatever), but at least it's another self-service data point besides the AirTag.
