Air freight refers to the transportation of goods and cargo by aircraft. It is a fast and efficient way to move products over long distances, making it ideal for time-sensitive shipments. Businesses often use air freight to deliver items such as electronics, pharmaceuticals, and perishable goods quickly. Air freight services are provided by various companies, including major airlines and specialized logistics firms. These services can include door-to-door delivery, customs clearance, and tracking options. The cost of air freight is generally higher than other shipping methods, but the speed and reliability can justify the expense for urgent deliveries.
