The card details had been stolen in a breach that took place between 21 August and 5 September. The stolen data did not include travel or passport details, according to latest reports.

BA boss has apologised for what he has called a very sophisticated breach of the firm’s security systems. Alex Cruz told the BBC: “There was a very sophisticated, malicious criminal attack on our website.”
