An airport cart is a wheeled vehicle designed to transport luggage and other items within an airport. These carts are typically made of metal or plastic and are available for passengers to use while navigating through terminals. They help travelers carry heavy bags, making the airport experience more convenient. Most airport carts can be found near check-in areas, security checkpoints, and boarding gates. Some airports charge a small fee for their use, while others offer them for free. Passengers can return the carts to designated areas after use, ensuring they are available for others.
