Course duration matters because air cargo training ranges from foundation learning to specialist programs. An IATA air cargo course in Kerala should be judged by what is taught, not by duration alone.
Speedwings lists IATA Cargo Introductory at six months and IATA Air Cargo Rating at four months. It also lists specialist programs such as Live Animals Regulations, Shipping Perishable Cargo, ULD Handling Awareness and Air Cargo Security with different durations.

Beginners may start with introductory cargo knowledge, while experienced professionals may choose a focused specialization.
