We have used a similar bright green straps for years. We always could spot our bags easily. I do have handmade handle wraps that go on each suitcase at the pull out handle and the two handles attached to the luggage used in lifting. We try to do self disembark, pack all necessities , swimsuits and one day and evening wear outfits in airline carryon. For Christmas we bought ourselves Apple AirTags. After reading about your troubles I am glad we did . So sorry you are going through this. The airline lost our luggage before our Panama Canal cruise. It was sitting on our porch 18 days later. My formal gowns, my husbands tux and all our other clothes inside. I am hoping your suitcase troubles are solved satisfactorily soon.
