What is the main reason behind luggage tagging?

Luggage tagging primarily serves the purpose of identifying and tracking bags along with their respective owners throughout the airport process. When a bag is tagged, it is assigned a unique identifier that is linked to the passenger's information. This helps airline and airport staff efficiently manage luggage from check-in, during transit, and finally to the baggage claim area. The tagging system enhances the reliability of locating bags should they be misplaced or misrouted, and it ensures that they are delivered to the correct destination as intended by the passenger. This coordinated tracking system is crucial for ensuring smooth operations and minimizing the chances of lost luggage.

While making luggage look unique, preventing loss, and charging for additional baggage are related aspects of travel, they do not encapsulate the primary function of luggage tagging as effectively as the correct answer does. Luggage tags provide essential information for both identification and tracking, which is vital for the entire baggage handling process at airports.
