Throughput is more than just a number – it reflects how well a checkpoint handles peak periods and maintains flow. High throughput helps prevent long queues and delays, while efficient processes ensure that security staff are deployed effectively. The challenge: balancing speed with staff efficiency in an environment where resources are limited and operational demands continue to grow.
Security checkpoints are complex systems, and bottlenecks can appear at several stages of the process. At divestment, limited stations for passengers to prepare trays can slow the entire lane and reduce scanner utilisation further downstream. Another common bottleneck occurs during image review, where CT scanners produce detailed 3D images that require more time to analyse. Bottlenecks can also occur in the reclaim area, where slow tray clearance can cause congestion and disrupt lane flow.
Beyond these points, factors such as staffing levels, training, passenger behaviour and even the design of the lanes all influence throughput. In short, bottlenecks aren’t just a matter of technology – they can be triggered by operational and behavioural circumstances.
Modern solutions can make a significant difference in improving throughput and efficiency. Central image processing – also known as multiplexed screening – enables parallel image review across several lanes or even entire airports, reducing idle time and speeding up decisions. Automated lanes, with features such as empty tray detection and automatic tray return, help keep reclaim areas clear and prevent congestion.
Looking ahead, connectivity and data integration open up new possibilities for improving checkpoint performance. By unifying data, airports gain real-time insights to make proactive decisions, such as adjusting capacity dynamically and managing queues more effectively. These capabilities help to optimise throughput and efficiency, while supporting a smoother passenger experience across the airport.
Passenger throughput is a critical performance indicator, but it’s only part of the story. True efficiency comes from integrating the right technologies into a solution that works for each airport – and taking collaborative action. By engaging stakeholders early and using workshops and simulations, it’s possible to explore different scenarios and make informed decisions. This approach ensures that the checkpoint is tailored to space, people and ambitions, while laying the foundation for sustainable, future-ready operations.
