I put Air Tags in all my items when traveling. I never know when I’ll forget to carry on my carry on items. Also very reassuring to know my checked bag has arrived at the destination airport, especially when it is one of the last ones to come out. Or when it doesn’t come out at all.
I flew home to San Francisco airport directly from France. My bag showed as being in the terminal. Eventually bags stop. Carrousel stops. No bag. Find a helpful agent. After literally a couple of hours (she was quite busy), she says that the bag was caught in the machinery and retrieval has to wait until shutdown at 3am. Go home, she says, and we’ll deliver it in the morning. Which they did. Good thing I wasn’t going on a connecting flight, as was a couple who had the same problem.
