Fast and accurate baggage handling

Once the 43km system is completed, an extensive system with the full length of 184㎞ is established. 184㎞ is roughly the distance of making two round trips between Incheon Airport and Seoul. Despite its complexity, the system can handle baggages quickly and accurately. In addition, the system uses explosive detection equipment integrated in lines with the BHS to inspect all baggages with speed and thoroughness.
