Air freight refers to the transportation of goods and cargo via aircraft. This method is often used for shipping items that need to reach their destination quickly, such as perishable goods, medical supplies, or high-value products. Air freight is typically more expensive than other shipping methods, like sea freight, but it offers faster delivery times, making it ideal for urgent shipments. Air freight services are provided by various companies, including major airlines and specialized logistics firms. These services can handle a wide range of cargo, from small packages to large freight containers. The process involves booking space on a flight, preparing the cargo for transport, and ensuring it meets all regulatory requirements for air travel.
