Baggage drop-off is a service provided at airports where passengers can check in their luggage before boarding their flight. This process allows travelers to leave their bags with airline staff, who then ensure the luggage is loaded onto the correct aircraft. It typically occurs at designated counters or kiosks, making it easier for passengers to move through the airport without carrying heavy bags. During baggage drop-off, travelers usually need to present their boarding pass and identification. After checking in their luggage, they receive a claim ticket, which they must keep safe to retrieve their bags upon arrival at their destination.
