Sorry, I'm been posting a lot of transportation threads today but I keep seeing them in my inbox and Google feed. This I was not aware of, and don't believe I've seen anything on the forum.
I know many of you are carry-ons only, but some of us do check bags and this is good info to have, in my opinion. In a nutshell, if your bag has not arrived at baggage claim after 20 minutes have elapsed from the time you landed and the doors were opened, Delta will pay you 2500 bonus miles. One caveat - this does not apply to international travel; only domestic flights (all 50 states and PR). But I fly domestic and I know many of you do, too, so still good info. 😊
You must file a claim (online at this link) within 3 days, and you must have been a Delta SkyMiles member at the time of the flight.
Note Delta's rules: The time to baggage claim will be defined as time elapsed between aircraft door open and delivery of the bag to the baggage claim belt. Oversize and overweight baggage and special items are not eligible. https://www.delta.com/bags/bagsClaimAutomation.action
