Imagine a situation: you fly from Los Angeles to Miami with checked luggage, arrive in Miami, and proceed to go straight to your hotel without ever picking up your bag. Assuming you never end up remembering about your luggage (for whatever reason), what would likely happen next? Would the airline try to email/call you or would they just shrug off and destroy your luggage after a few days?
I’m primarily interested in what will happen on US flights but international answers might be good too.
