An aviation coalition has called on the European Union to safeguard the voluntary use of biometrics as Brussels reviews data rules through its Digital Omnibus package, FlightGlobal reports.

The coalition's concern centers on how the Digital Omnibus — the EU's planned simplification and overhaul of digital legislation, including the GDPR framework — will treat biometric identification at airports. Airlines and airports have invested heavily in biometric touchpoints, from bag drop to boarding, on the promise that passengers can opt in rather than be compelled to submit facial scans.

The industry grouping fears that changes under consideration in the Omnibus could remove legal certainty around that voluntary basis. If biometric processing ends up effectively mandated, or if the legal grounds for consent-based processing are narrowed, carriers and hub operators face a compliance rethink across systems already deployed at scale.

For airlines, the stakes are operational as much as legal. Biometric corridors have become a lever for processing more passengers through the same terminal footprint — a capacity question at congested European hubs. Any rule change that complicates voluntary enrollment threatens the throughput gains and cost savings the technology was bought to deliver.

The coalition's appeal adds aviation to the broader corporate pushback against the Digital Omnibus, which businesses argue has introduced regulatory uncertainty even as it promises to cut red tape. Consumer groups and some lawmakers counter that weakening consent standards would erode data protection rights.

How Brussels resolves the voluntary-biometrics question will shape airport technology procurement and passenger-processing strategies across the EU for years to come.
