TL;DR: Sensitive airline passenger, payment and commercial data now sits across core systems, emails, spreadsheets and AI-ready repositories, according to Ground Labs. That sprawl turns PAN and PCI governance into an inventory problem before cloud access widens it further.
Editorial analysis by NHI Mgmt Group, based on content published by Ground Labs: “Next-Generation Risk Mitigation for Airlines: A Data Intelligence Guide”.
By the numbers:
- Airlines saw a 600% increase in cyberattacks in 2025, according to Ground Labs.
- Requirement 12.5.2 requires scope to be documented and confirmed at least every 12 months and following significant changes, according to Ground Labs.
- Ground Labs says more than 300 predefined data types are covered for payment and personal information across over 50 countries.
Key questions
Q: What breaks when sensitive passenger data is copied outside core airline systems?
A: The original control boundary breaks down.
Q: When should airlines prioritise data discovery over broader security projects?
A: They should prioritise it when they do not yet know where regulated data resides, who can access it or whether it still needs to be kept.
Q: How should airlines reduce data exposure before connecting AI systems?
A: Airlines should remove unnecessary sensitive data from the repositories that AI can reach, then enforce retrieval and permission boundaries before deployment.
Practitioner guidance
- Build a unified discovery map for passenger and payment data Scan on-premises, cloud and collaboration systems for passenger records, card data and other sensitive fields, then consolidate the results into a single inventory that includes copies, derivatives and exports.
- Separate AI-connected repositories from raw sensitive data Remove unnecessary passenger, loyalty and operational content from repositories that feed AI assistants, and restrict retrieval paths to the minimum dataset needed for the use case.
- Review PCI scope after every material process change Reconfirm where cardholder data exists after new support channels, partner workflows or analytics exports are introduced, because scope drift often starts outside the payment platform.
Bottom line: Airline data sprawl turns privacy and PCI obligations into a discovery problem because sensitive records are often copied beyond the original control boundary.

Airline data discovery is now an access-control problem, not just a compliance task. Once passenger, payment and commercial data is duplicated into support channels, cloud storage and analytics extracts, the question is no longer only whether it exists. The question becomes who can see it, where it was copied and whether the copy is still justified. That makes discovery a prerequisite for any credible governance model in regulated transport.
A few things that frame the scale:
- 43% of security professionals are concerned about AI systems learning and reproducing sensitive information patterns from codebases, according to the State of Secrets in AppSec.
A question worth separating out:
Q: Who is accountable when PAN is discovered outside the defined cardholder data environment?
A: Accountability sits with the organisation that owns the payment environment and its incident response process, not with the storage location alone. PCI DSS expects documented procedures for finding the source of the leak, assessing related sensitive data, and correcting the process gap. Security, compliance, and system owners must coordinate so the data is removed, secured, and prevented from reappearing in unexpected places.
