Airlines have had several high-profile breaches in recent years. In 2018, Hong Kong's Cathay Pacific Airways Ltd. disclosed that hackers accessed information on 9.4 million customers, making it the world's biggest airline data breach at the time. "The EasyJet breach comes at a time of unprecedented challenge for airline operators," said James Castro-Edwards, a partner at law firm Wedlake Bell. The potential consequences of "enforcement action and any ensuing group litigation are catastrophic," he added.
