What principle should be used to sort baggage?

The principle that should be used to sort baggage is the first-off, last-on principle. This method is rooted in the logistics of loading and unloading baggage in an aircraft. When luggage is loaded onto the plane, the last pieces placed on top are often the first to be unloaded upon reaching the destination. This ensures that bags can be easily accessed without the need for moving others out of the way, facilitating smoother and quicker baggage retrieval for passengers once the flight is concluded. Adhering to this method helps maintain an organized flow in airport operations, enhancing efficiency for both the airline and departing travelers.

In contrast, the last-off, first-on principle would create challenges during baggage claim, as the last items loaded would be the first removed, potentially leading to delays and confusion for passengers retrieving their bags. Weight-based sorting and priority-based sorting do play roles in baggage management, particularly concerning balance and special handling, but they do not directly address the loading and unloading sequence as effectively as the first-off, last-on principle does.
