Marriott Data Breach Settlement 2026 — File Your Claim

The Marriott/Starwood data breach stands as one of the most significant hospitality industry security failures in history. Beginning in 2014, years before Marriott completed its $13 billion acquisition of Starwood, intruders had already established persistent access to Starwood's central reservation system. By the time the breach was discovered and disclosed in late 2018, approximately 500 million guest records — accumulated over four years — had been potentially compromised.

What makes the Marriott breach uniquely serious is the nature of the data exposed. Unlike retail breaches that primarily capture payment card numbers (which can be replaced), the Starwood reservation database contained passport numbers, which remain valid for 10 years and cannot be canceled once exposed. For frequent international travelers who stayed at Starwood properties across multiple countries, the breach created a long-duration identity fraud risk that is difficult to fully mitigate.

Marriott International reached a $52 million settlement in 2022 with attorneys general from 49 states and the District of Columbia, acknowledging security failures spanning the acquisition period. Separate class action litigation resulted in a settlement fund for affected guests. Both settlements affirm that Marriott's security practices fell short of legal standards despite the company's extensive resources and operational scale.
