Luggage lockers are secure storage units found in various locations, such as airports, train stations, and tourist attractions. They allow travelers to safely store their bags and belongings for a few hours or even days, providing convenience and peace of mind while exploring an area without the burden of carrying heavy luggage. These lockers come in different sizes and can typically be rented for a fee. Users can access their items using a key, code, or electronic system. Luggage lockers are especially useful for those with long layovers or early check-ins, making travel more enjoyable and hassle-free.
