A baggage claim tag is a small label attached to luggage when checking it in at an airport. This tag contains important information, such as the passenger's name, flight number, and destination. It helps airline staff track and manage checked bags, ensuring they reach the correct location. When a flight arrives, passengers can find their luggage at the baggage claim area by matching the claim tag on their bag with the information on the tag. This process helps prevent lost luggage and ensures that travelers retrieve their belongings efficiently after their journey.
