One way to ensure the safety of your luggage is to make it unique or easily identifiable to you. Consider using a bag that stands out in a crowd or can be spotted easily. If that's not possible, you can still make your luggage stand out by using markers that are relevant to you. For instance, you may opt for luggage tags that are of bright colour, a cover with a unique design, or stickers that make it easy for you to spot your bags. This way, you will have a better chance of identifying your luggage quickly and easily, and you'll also make it less likely for someone to mistake your bags for theirs.
