A baggage drop system is disclosed for depositing and checking of baggage into airline flights. The baggage drop system can include a substantially horizontal frame member. The frame member can be mounted above a first conveyor equipped with a static or dynamic weighting scale. The frame member can also be mounted away from an end of the first conveyor at a distance from an upper surface of the first conveyor substantially equal to a maximum allowable height of baggage thereby forming a physical barrier for oversized baggage. A computer can be configured to compare an output of the weighing scale with allowable baggage weights.
