Which statement accurately describes items that can be shipped by air?

The assertion that anything fitting into a commercial aircraft's cargo hold can be shipped accurately reflects the capabilities and regulations of air transportation. While there are restrictions and specific regulations regarding what can be shipped via air, the fundamental principle is that items that fit within the size and weight limits established by airlines can indeed be transported.

Air freight is commonly used for a wide range of products, including non-perishable goods, hazardous materials (under strict regulations), large machinery, and high-value items. The flexibility in air shipping is one of its primary advantages, allowing businesses to transport goods quickly across long distances.

It's important to note that options suggesting limitations—such as only hazardous materials or only perishable goods—overlook the broad spectrum of items that can be legally and operationally shipped by air. Size restrictions are determined by airline policies and cargo space availability rather than a blanket requirement that items must be small. Thus, the correct characterization highlights the general inclusivity of air shipping.
