Cargo airlines are specialized airlines that focus on transporting goods rather than passengers. They operate a fleet of aircraft designed to carry various types of cargo, including packages, freight, and oversized items. These airlines play a crucial role in global trade by ensuring that products reach their destinations quickly and efficiently. Many cargo airlines operate on scheduled routes, while others provide charter services based on demand. Major cargo airlines, such as FedEx and UPS, utilize advanced logistics and tracking systems to manage shipments. They often collaborate with other transportation methods, including trucks and ships, to deliver goods worldwide.
