British Airways Plc faces the largest privacy class-action lawsuit in UK history over its 2018 customer data breach. More than 16,000 victims have now joined a case seeking compensation from the airline. They could claim 2,000 pounds ($2,724) each, according to PGMBM, the law firm representing the claimants. “We trust companies like British Airways with our personal information and they have a duty to all of their customers and the public at large to take every possible step to keep it safe,” Tom Goodhead, a partner at PGMBM, said in an email. “In this instance, they presided over a monumental failure.” IAG SA-owned BA revealed in September 2018 that a violation of its security systems compromised the personal and financial details of more than 400,000 customers. The carrier was fined 20 million pounds by the UK data protection watchdog last year, a fraction of a much heftier fine initially planned by the regulator.
