Purchase matching luggage in a bold color so it stands out from the common black bags.
Attach a large, brightly colored luggage tag on the handle of your suitcase. Use the same tag on all your bags. Preferably, use tags that close or have a privacy flap so your personal information isn't easily viewable.
Tie a wide, distinctive-looking ribbon around the suitcase, using the same ribbon for all the luggage you are carrying. Ribbons that contrast with the color of the luggage help the bags stand out in the baggage claim area. Alternatively, use a colorful luggage strap.
Wrap colored duct tape around the handles. The duct tape stands out, especially on plain black bags.
Decorate hard-sided suitcases with large decals. Place the decals on both sides of the suitcase so they are visible regardless of how the bag lands on the baggage carousel.
Tie silver ribbon to the handle of black suitcases, or wrap metallic silver pipe cleaners around the handle. Silver stands out against the black.
