On May 26, 2026, the Spanish Data Protection Agency (“AEPD”) published details of its decision to fine Amadeus IT Group, S.A. (“Amadeus”), a Madrid-headquartered technology provider for the global travel and tourism industry, EUR 18 million in connection with GDPR violations involving Amadeus’s Global Distribution System (“GDS”). Amadeus voluntarily paid the fine, less a 20% reduction, on May 29, 2025, thereby terminating the proceedings without admitting liability. The fine, one of the largest the AEPD has imposed, highlights the enforcement risks associated with repurposing personal data such as passenger data without appropriate transparency or a valid legal basis under the GDPR.
