The author Douglas Adams once quipped that nobody has ever uttered the phrase ‘as pretty as an airport’.
He had a point. Think back to a recent journey, and you probably don’t recall the architecture, but the queues, document checks, intrusive machinery and delays can make even a routine journey stressful.
The "touchless airport" concept has been around for years. What has changed is the maturity of biometric systems and digital identity technologies. The industry increasingly believes the technology is ready. The question is whether governments are prepared to permit it.
Speaking during a recent IATA media briefing on the association's Global Passenger Survey, Senior Vice President Operations, Safety and Security Nick Careen said the industry has already demonstrated that digital travel credentials can work in practice. Multiple international proof-of-concept projects have shown that travellers can use a digital identity throughout the journey, from booking and check-in to border control and arrival.
"We've illustrated it does work," Careen said. "But we do need the governments to change their regulations to allow for it."
Ready for change
The survey findings suggest passengers are more than ready for such a transformation. Nearly 60% of respondents reported using biometrics during travel in the past year, while more than 80% expressed interest in digital passports and digital wallets containing travel credentials. In many respects, consumer demand is now running ahead of implementation.
The concept is simple. Rather than repeatedly presenting passports, boarding passes and identification documents at different stages of the journey, passengers would be able to use a secure digital credential verified through biometric technology. The result could be shorter queues, reduced friction at airports and a more efficient travel experience.
For airports facing growing passenger volumes and capacity constraints, the potential benefits are significant. Digital identity technologies could streamline security, immigration and boarding processes without necessarily requiring major infrastructure expansion.
However, Careen believes regulatory frameworks have yet to catch up with technological capabilities.
Data privacy remains one of the biggest hurdles. Governments must determine how personal data can be stored, shared and verified while ensuring compliance with privacy legislation. Border agencies must also adapt existing regulations, many of which were built around physical document checks rather than digital credentials.
Europe could become the first major proving ground for large-scale implementation. Careen highlighted initiatives surrounding Digital Travel Credentials and suggested the region is likely to be at the forefront of deployment over the remainder of the decade.
"I would guess that we're between now and 2030 before we start to see some real meaningful usage of digital travel credentials," he said, adding that widespread adoption could occur within the next three to five years if the necessary regulatory changes are made.
Political Will
That timeline is notable because it shifts the conversation away from technological readiness and towards political willingness. The aviation industry is no longer asking whether digital travel is possible. Instead, it is asking how quickly governments can create the legal and regulatory frameworks needed to support it.
The implications extend beyond passenger convenience. IATA's survey also found growing frustration with immigration procedures and border requirements, with many travellers reporting that complexity and administrative burdens discourage international travel. Streamlined digital processes could therefore support tourism, international connectivity and economic growth while improving operational efficiency for airlines and airports.
The fully digital passenger journey may no longer be waiting for a technological breakthrough. It may simply be waiting for lawmakers.
