Cargo flights are specialized flights designed to transport goods and materials rather than passengers. These flights can carry a wide range of items, including electronics, clothing, and perishable goods. Cargo planes are often larger than passenger planes and have unique features, such as a large cargo door for easy loading and unloading. Airlines that operate cargo flights may use dedicated cargo planes or convert passenger aircraft for freight use. Major cargo carriers include companies like FedEx and UPS, which provide global shipping services. Cargo flights play a crucial role in international trade, ensuring that products reach their destinations quickly and efficiently.
