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, such as FedEx Express and UPS Airlines, offer services that include overnight delivery and international shipping. They often use dedicated cargo planes, which have larger cargo holds and are equipped to handle different types of freight. This allows businesses to rely on timely deliveries for their operations and supply chains.
