the answer is simple: ribbons can interfere with the automated system that scans luggage before it is loaded into the aircraft’s hold. These machines operate at high speeds and are extremely sensitive; they need an unobstructed view to read barcodes.
If a ribbon, a large keychain, or even an old sticker covers the scanning area, the machine stops. As a result, the suitcase must be checked manually, which slows down the process—and, in the worst-case scenario, could even mean your luggage doesn’t make it onto the plane at all.
