Goodbye Queues: Biometrics May Soon Manage Travellers at Airports!

Airports around the world are exploring new ways to improve security, ease congestion, and enhance the travel experience. One of the most promising innovations under consideration is the use of biometric digital ID technology to manage the segregation of international and domestic departing passengers.

As airports become busier and travel rebounds globally, this technology could offer a more efficient and secure alternative to traditional methods. Recently, the International Air Transport Association (IATA) released a study showing substantial cost savings, operational efficiencies, passenger experience and sustainability gains can be made by using biometric digital ID technology to manage the segregation of international and domestic departing passengers at airports where they are currently separated by physical barriers. 

The Domestic and International Passenger Integration Programme (DIPIP) report was a joint effort with AtkinsRéalis, an engineering services and project management company.

IATA’s Senior Vice President for Operations, Safety and Security Nick Careen said: “Regulatory requirements and technology limitations have meant that domestic and international departure passenger flows need to be physically separated at many airports.

 That’s no longer the case. Digital ID powered by biometrics can achieve the needed segregation without creating a physically separated flow with duplicated facilities which is inefficient and costly. “The study shows that segregating passengers with digital ID will lead to a better travel experience for travellers, reduce costs for airports and airlines, and maintain security and border control requirements.

It’s a compelling case for a much-needed modernisation.” “The publication of this report is key in understanding how the concepts of digital identity and use of biometrics can play a significant role in improving passenger experience and creating substantial cost savings which will have benefits across the aviation sector.

We have a strong working relationship with IATA and were delighted to work on this study, drawing on our own broad experience of integrating biometrics into the passenger journey,” said Gareth Vest, UK&I Aviation Market Director at AtkinsRéalis. 

The study quantified the following benefits from segregating departing passengers with biometric enabled digital ID. 

Improved passenger experience: Removing physical barriers between domestic and international departure flows will improve passenger satisfaction with simplified journeys and shorter processing times.

Minimum connection times, for example, could be reduced by nearly 20% with the efficiencies gained. Cost savings: Shared facilities eliminate duplication in infrastructure, utilities, and staffing, reducing maintenance, operating, and construction costs for airports, airlines, and ground handlers. Case studies at major international airport identified up to a 11% reduction in airport staff costs, while a ground handing company estimated a $5.3mn annual saving at another leading airport. More efficient use of airport infrastructure: Enabling departing passenger flows to use the same physical space allows airports to serve more passengers within existing terminal footprints, optimising use of space and the services within it. Sustainability benefits: Consolidation reduces energy use and construction-related emissions.

Operational flexibility: Shared facilities allow airports, airlines, and ground handlers to better manage fluctuating passenger volumes and deploy resources where needed. This is particularly important given that international and domestic departures often concentrate at different times during the day. “The savings quickly add up.

A medium-sized airport serving 10mn passengers annually could save up to $80mn of future capital expenditure and considerable annual operational savings through the removal of duplicate facilities and improved operational flexibility, while reducing its annual carbon footprint by 18,000 tonnes — the equivalent of removing 4,000 cars from the road for a year. The case for change is clear. Managing departing passengers with digital ID instead of physical barriers delivers efficiency, emission reductions, and a smoother experience for travellers,” Careen noted. Biometric digital ID technology is certainly not a distant concept - it is becoming a central feature in the future of aviation.

While privacy protections and regulatory frameworks remain crucial, the potential benefits for security, passenger flow, and operational efficiency are compelling. Analysts say that if adopted widely, the segregation of international and domestic passengers may one day happen not through barriers and manual checks, but through a smart, seamless, and highly secure digital system — quietly operating in the background from the moment the passenger enters the terminal!
