US Patent 12014580 System for baggage check-in

The disclosure includes a system for checking in baggage of a passenger. The system includes an electronic acquiring device that acquires an originating hardcopy bag tag identifier (OP-BTI) associated with or printed on a printed bag tag from an originating airline travel carrier that is on a luggage item of a passenger. This creates a digital BTI data record linked to the airline travel carrier. The system further includes utilizing the OP-BTI as a unique identifier to query a database to retrieve return flight data of the passenger. The system includes checking in, by the at least one processor, each luggage item for the passenger for the return flight with a return flight travel carrier identified in the retrieved return flight data.
