Having been forced to fly numerous times in the last several years..... I can tell you stories..... Spokane, Dallas, Minneapolis, Atlanta, Philadelphia, etc My best advice is to put Tiles, and Apple Airtags in each suitcase that has important things in it (we have both types of phone in the family) doubling up more then doubles your chances to get more pings. If you have that, you can actaully know where your bags are.... There have been cases where it actually is in the correct airport but sitting on a cart in the wrong terminal. and you can show them and sometimes get a kind person to go retrieve it
And also we started shipping certain items ahead by UPS or USPS with guaranteed delivery to trusted people .... a week or more prior. So we know before we leave that those items have already arrived where we need them. Its not bulletproof..... but it has worked and gives a certain peace of mind knowing that our things are already there....
