Automated and Sustainable: The Next Era of Airport Technology

Modern airports are complex ecosystems where efficiency, security, and passenger experience must intertwine. No longer viewed as mere transit points, they are constantly evolving into sophisticated, future-ready hubs. As we look toward 2026, the convergence of advanced automation, intelligent infrastructures, and green solutions is set to define the next paradigm of airport management and passenger processing.

This article delves into emerging technologies that will significantly impact terminals and operations and offers insights for decision-makers steering the course for airports in the years to come.

Automation is moving beyond simple passenger-facing self-service to a truly intelligent and interconnected environment where processes are optimised in real time. Artificial intelligence (AI), machine learning, and robotics are the cornerstones of this development, elevating everything from passenger flow and security screening to operational resource management.

• Biometric journeys: The concept of the 'single token' passenger journey relies on biometric authentication to create a persistent digital identity for each traveller. By leveraging advanced facial recognition cameras and sensors, a seamless path is created for passengers, allowing them to walk uninterrupted from check-in to the boarding gate. The 2025 Global Passenger Survey by the International Air Travel Association (IATA) indicates a growing preference for this innovation, with 74% of their respondents willing to use biometrics if it means skipping traditional checkpoints.
• AI-enhanced security screening: The use of artificial intelligence (AI) is becoming the new baseline for airport security. When coupled with AI-driven algorithms and image analysis, baggage and personnel scanners can automatically detect prohibited items with higher accuracy than human operators alone. Adopting smart security solutions ensures consistent performance, free from fatigue or bias, thereby minimising the likelihood of false positives and unneeded manual searches.
• Robotics for apron and baggage operations: As cargo volumes rise and operational demands intensify, robotics streamline processes, minimise manual labour, and bolster security. From self-driving, self-navigating autonomous vehicles like Automated Guided Vehicles (AGVs) and Autonomous Mobile Robots (AMRs) to drones and robotic arms, robotics deliver increased speed, precision, and dependability to logistics operations.

The digital transformation of airports is not just about processes but also about transforming physical infrastructure into a dynamic, responsive asset. Terminal facilities are being built to adapt to the needs of their occupants and operators through the integration of Internet of Things (IoT) sensors and building management systems.

• Intelligent lighting: By integrating flight information systems and occupancy sensors, lighting can be dynamically adjusted to save energy by up to 70%. By changing colour, intensity, or pattern, the lights can function as a wayfinding tool, guiding passengers towards their gate, baggage reclaim, or emergency exits.
• IoT-enabled asset tracking: Deploying an extensive network of IoT sensors enables real-time visibility of assets, from baggage carts to cleaning robots. This facilitates efficient allocation, maintenance scheduling, and theft prevention.
• Occupancy and flow analytics: Sensors embedded in floors, ceilings, or doorways provide anonymised data on passenger movement patterns and density. This information can be used to direct cleaning schedules, optimise queue management, and ensure comfortable occupancy levels throughout terminals.

Sustainability has transitioned from a peripheral concern to a central pillar of airport strategy. Technology is the primary enabler of this shift, offering innovative solutions to reduce the environmental footprint of airport operations.

• Closed-loop water systems: In its 2025 Environmental Report, the International Civil Aviation Organization (ICAO) promotes the use of closed-loop systems in airports to address environmental mandates and conservation concerns. Also known as a circular economy, a closed-loop system considers waste as a design flaw, with the aim of extending the life cycles of products through repair and refurbishing, and restoring natural resources.
• Electrification of ground support equipment (GSE): The transition from diesel to the electrification of GSE offers advantages such as zero exhaust emissions, lower maintenance requirements, and improved energy efficiency.
• Advanced waste management: Smart bins equipped with ultrasonic sensors monitor fill levels and transmit data to a central platform, which then optimises collection routes. Furthermore, AI-powered sorting systems are being deployed in waste processing facilities to achieve higher recycling and recovery rates than manual sorting can deliver.

As the pace of technological innovation continues to accelerate, airports must remain adaptable and forward-thinking. Investing in staff training, fostering collaboration with technology partners, and engaging with passengers will be vital to ensure new systems deliver their full value. By focusing on both innovation and human experience, the airports of the future can lead the way in creating more efficient, sustainable, and welcoming environments for all travellers.
