On July 8, the regulator fined British Airways an eye-popping £183 million ($228 million) for leaking the personal data of 500,000 of its customers. Marriott International got slapped with a fine of just over £99 million ($124 million) for exposing a variety of personal data in 339 million guest records globally. BA and Marriott have 21 days in which they can make representations to fight their corner and try and reduce the fines.
