While having a matching luggage set looks aesthetically pleasing and organized, in 2026, many travel experts actually advise against it for security and logistical reasons. If all your bags are the same color, especially a common one like black or navy, it becomes significantly harder to identify your specific bag on a crowded baggage carousel. Furthermore, if one bag is lost, providing a description like "three identical blue suitcases" makes it harder for airline staff to distinguish between your items. A better strategy is to use a "coordinating" rather than "identical" set, or to apply unique identifiers like brightly colored luggage straps or high-visibility tags to each piece. This ensures your bags stand out to you (and only you) while reducing the risk of someone else accidentally grabbing your luggage thinking it is their own identical set.
