Hong Kong International Airport and Air New Zealand became the first organizations in aviation history to earn IATA’s One ID Certification on October 28, 2026, marking the first time an independent, verified standard has been applied to the biometric identity systems that let travelers skip repeated passport checks at the airport. For the 93 million passengers who have already used HKIA’s Flight Token system since its 2021 launch, the certification means the privacy and data-handling processes behind those face scans have now been audited against a global standard — and a planned public Trust Registry will eventually let any traveler verify whether an airport or airline meets the same bar before they decide to enroll.
The certifications were presented at the IATA World Passenger Symposium in Macao.
What IATA One ID Certification Means — and Why It Differs from Just Having Biometric Gates
Having facial recognition at an airport and being certified under One ID are not the same thing. IATA’s One ID standard requires organizations to demonstrate compliance across four distinct areas: Digitalization of Admissibility, Contactless Travel, Biometric Handling, and Privacy, Consent, and Governance. An airport can install cameras and biometric kiosks without meeting the decentralized digital identity, selective disclosure, and interoperability requirements that One ID mandates.
Both Air New Zealand and HKIA were certified across all areas applicable to their respective operations — the maximum possible scope for each type of organization. The IATA One ID Certification program is valid for two years, after which re-certification is required.
“Digital identity can make travel much simpler for passengers, but only if everyone involved in the journey trusts how others verify identity, handle biometric data, and protect privacy,” said Nick Careen, IATA’s Senior Vice President for Operations, Safety and Security. “One ID Certification gives them that assurance.”
IATA’s 2026 Global Passenger Survey found that 78% of passengers would share biometric data to avoid presenting physical travel documents at airport checkpoints — but many of those currently unwilling say they would reconsider if data privacy were assured. The certification is designed to provide that assurance in verifiable, third-party-audited form.
How Flight Token Already Works for Travelers Departing Hong Kong
Flight Token is HKIA’s self-service biometric identification system, operational since 2021 and now deployed across every departure checkpoint in the airport. More than 80% of departing passengers at HKIA are eligible to use it.
Enrollment is integrated into the normal check-in process. Passengers complete check-in at a Smart Check-in Kiosk or counter, where a Flight Token is created linking their travel document and boarding pass to a facial biometric. From that point, face scans replace document presentation at the e-Security Gates, e-Boarding Gates, and — for Hong Kong residents — immigration departure clearance. Passengers flying with airlines whose check-in doesn’t automatically create a Flight Token can enroll at the e-Security Gates by scanning their travel document and boarding pass, as described in HKIA’s Flight Token passenger guide.
Since its launch, more than 93 million passengers have used Flight Token. The system won the Best Innovation in Airport Passenger-Related Processes award at the Amadeus and ACI World Technology Innovation Awards in 2021.
“Flight Token has transformed the departure journey by enabling passengers to travel through key airport checkpoints using facial recognition,” said ViKong. “As we work with airlines, airports, and government authorities to expand Flight Token beyond Hong Kong, this certification provides a trusted foundation for interoperable and seamless digital travel.”
Air New Zealand’s Cross-Border Digital ID Trial Showed It Works on a Live Route
Air New Zealand conducted a digital identity trial on the Auckland–Hong Kong route in March 2026, testing whether an airline-managed approach could integrate biometric identity across an international journey without repeated document presentation. The trial connected four systems through the passenger’s phone: the New Zealand Traveller Declaration, the IATA Travel Directory, HKIA’s Flight Token framework, and Air New Zealand’s own check-in platform, as detailed in the Air New Zealand newsroom.
Passengers added passport information to the Air New Zealand app during online check-in, with that verified identity then used at biometric touchpoints across the return journey. The trial demonstrated cross-border interoperability between an airline’s app-based system and an airport’s biometric infrastructure — a key requirement for One ID’s vision of a seamless multi-leg journey.
“Our trial with Hong Kong International Airport showed how digital identity could work across borders, reducing the need for documentation and queuing, but it also showed that customers can trust us to keep their information safe,” said Jeremy O’Brien, Air New Zealand’s Chief Customer and Digital Officer. “The certification recognizes the work we’ve done to date and the importance we place on protecting our customers’ personal information.”
Air New Zealand has identified Australia as the next market for a broader pilot expansion, though a specific launch date has not been announced.
What a Planned Trust Registry Means for Travelers Who Want to Verify Biometric Systems
IATA has announced plans to publish a public One ID Trust Registry listing all certified organizations. Once live, the registry would allow travelers, airlines, airports, and government authorities to check which organizations have met IATA’s privacy, governance, and interoperability standards before deciding to enroll in a biometric program or route traffic through a certified airport.
No date has been set for the registry’s launch. In the meantime, IATA supports adoption through a Contactless Travel Directory — a resource that lets airlines, airports, and border authorities find and connect to multiple biometric partners through a single integration — and through Timatic AutoCheck, which automates travel document verification. IATA is also working with governments to remove regulatory barriers to Digital Travel Credentials, the digital passport equivalents based on standards from the International Civil Aviation Organization.
IATA represents more than 370 airlines accounting for approximately 85% of global air traffic, making the One ID standard an industry-wide signal rather than a niche specification.
Passports Are Not Going Away — What the Standard Does and Doesn’t Cover
One ID certification applies to departure-side processing at airports and the airline-managed identity flow — the checkpoints between check-in and the gate. It does not eliminate passport requirements for international border control. Travelers arriving in another country still present physical passports and travel documents to immigration authorities as required by each destination’s entry rules. Hong Kong residents using Flight Token can pass immigration departure clearance by face scan, but inbound immigration at the destination is governed by that country’s own rules.
Conventional, document-based processing remains available alongside biometric options, and IATA’s One ID framework retains these manual channels for travelers who choose not to share biometric data.
For travelers departing HKIA today, Flight Token enrollment is available through the normal check-in process at no additional cost. For Air New Zealand passengers, the digital ID system is available through the airline’s app, with Australia routes the next planned expansion.
