A few years ago, facial scans and biometric gates at airports triggered unease among travelers. Today, most passengers not only accept the technology—they actively prefer it. According to SITA’s 2025 Passenger IT Insights Report, biometric screening is fast becoming the standard for air travel, marking a dramatic shift in global attitudes toward digital identity and automation.

The Rise of Biometric Comfort

Once associated with privacy concerns and skepticism, biometric identification is now embraced by the majority of passengers worldwide. SITA’s report shows that only 31% of travelers have never used biometric screening in 2025, compared to 41% just a year earlier—a clear indicator of growing comfort with the technology.

The report, which surveyed 7,500 passengers across 25 countries, highlights that younger travelers, men, and frequent flyers are leading the adoption wave. The Asia-Pacific and Middle East/Africa regions show the fastest uptake, driven by youthful populations and widespread smartphone penetration.

“Once people experience it, they rarely want to go back,” the report noted. What used to be a long wait at check-in or immigration is now reduced to a simple face scan—speeding up processing times by as much as 30–40%, according to airport operations data.

Everyday Tech Habits Fuel Airport Adoption

Experts say the shift in traveler attitudes is closely tied to how biometric technology has entered daily life. From unlocking phones to authorizing bank payments, facial and fingerprint recognition are now routine.

“Consumers expect everything to be instant—thanks to services like Uber and Netflix—and travel is no exception,” said Sarah Samuel, Senior Vice President of Airport and Airline Operations at Amadeus.

In fact, Amadeus has already rolled out biometric boarding and immigration systems in Singapore, Japan, Australia, India, and Indonesia (Bali). Airports that once struggled with long queues now report smoother flows and shorter wait times. Samuel described Bali’s transformation vividly: “You used to see endless immigration lines. Now? It’s practically an empty hall.”

The Future: Digital IDs and Proximity Biometrics

The next frontier in air travel technology is digital identity wallets—secure digital IDs stored on a traveler’s phone. These can seamlessly connect to airport touchpoints such as check-in kiosks, bag drops, and boarding gates without manual verification.

Amadeus is preparing to launch proximity biometrics across Asia-Pacific in the next year. The system automatically recognizes passengers within range and authenticates them securely. Importantly, all data is deleted once the passenger departs, ensuring privacy compliance.

SITA’s research shows rising comfort levels with digital IDs: 79% of travelers in 2025 said they’re willing to share biometric and identity data before flying, up from 74% in 2024. The company projects that the number of digital identity users will skyrocket from 155 million in 2024 to 1.27 billion by 2029—a more than eightfold increase.

Data Privacy: The Lingering Concern

Despite the convenience, privacy fears continue to shadow biometric adoption. SITA found that 97% of passengers still have some level of concern about how their data is stored or used. Only a small 3% said they have no worries at all.

Another survey by Qlik, covering 4,000 respondents across Asia-Pacific, revealed that while travelers are open to sharing booking or budget data, they’re far more cautious about live location and identity information.

Cultural factors play a major role: Indian travelers showed the least concern about data privacy, while Japanese passengers were the most cautious—34% said they were uncomfortable sharing any personal data. “Age and culture make a huge difference,” Samuel noted. “Younger populations tend to prioritize convenience, while older generations focus more on security.”

Faster, Smarter, and Lighter Travel

Despite ongoing concerns, the allure of faster and paperless travel is undeniable. Biometric boarding gates and mobile-based digital IDs reduce the need for physical passports and documents, cutting check-in and boarding times dramatically.

For many frequent travelers, the change has been life-altering. “I barely carry anything when I travel now,” Samuel said. “Everything—my passport, boarding pass, even credit cards—is on my phone.”

This transition represents a broader technological shift that mirrors how digital wallets transformed payments. As air travel rebounds globally and airports race to modernize, biometric and digital identity systems are set to redefine passenger experience—turning what was once a point of anxiety into one of convenience and confidence.

The Bottom Line

The transformation in traveler sentiment toward airport biometrics underscores a pivotal moment in aviation. What began as a cautious experiment is now a cornerstone of modern air travel—streamlining journeys, enhancing security, and paving the way for a truly contactless travel experience.

Still, as technology advances, the challenge remains to balance convenience with trust. The airports and companies that succeed will be those that not only innovate quickly but also safeguard passenger data with the same precision as they process it.
