What is transported in an air tray?

An air tray is specifically designed for transporting casketed remains. It is a lightweight, collapsible shipping container used primarily by funeral homes to facilitate air travel. The structure of an air tray enables proper ventilation and protection during the transport process while ensuring that the casketed remains are kept secure.

When transporting cremated remains, funeral flowers, or embalmed bodies, different types of containers are utilized. For example, cremated remains are typically placed in urns or other appropriate containers, while embalmed bodies are transported in more robust shipping containers that comply with health regulations. The unique design of an air tray focuses on the needs associated with casketed remains, making it the correct answer in this context.
