The invention relates to a baggage drop system for depositing and checking of baggage into airline flights. The system comprises a conveyor (1), equipped with a static or dynamic weighing scale (17), comprising multiple, spaced apart load cells (18), and computing means adapted to compare the output of the weighing scale (17) with allowable baggage weights, and a substantially horizontal frame member (2′), mounted above the first conveyor (1) at a distance from the upper surface of the first conveyor (1) equal to the maximum allowable height of baggage, thereby forming a physical barrier for oversized baggage. The system allows to check for the presence of living creatures on the conveyor belt, and for conformity with baggage handling system requirements. The system may further comprise a baggage check-in apparatus (3) to allow automatic baggage check-in by a passenger, including means for payment (12) of excess and/or overweight baggage. The invention further comprises a method for checking in of baggage items using the baggage drop system in accordance with the invention.
