Why are "hot bags" also known as "rapid bags"?

"Hot bags," commonly referred to as "rapid bags," are designated as such because they need to be handled quickly due to the short connection times of the flights they are designated for. This term reflects the imperative nature of their processing, ensuring that they reach their destination without undue delay, which is critical in maintaining tight schedules for connecting flights. This efficiency helps prevent missed connections for passengers who are transferring from one flight to another.

The other options, while they may contain elements related to airport operations and regulations, do not reflect the core reason behind the terminology. For instance, the association of "hot bags" with special flight categories or restrictions on international flights does not accurately capture the urgency of their handling, nor do pre-approval requirements for cargo apply to their definition or operational context. Thus, the term predominantly emphasizes the need for prompt action in managing these bags to meet connection demands.
