British Airways said that the personal and financial details of customers making bookings between August 21 and September 5 had been stolen in a data breach involving 3,80,000 bank cards.

The almost two week long hack did not involve travel or passport details, the airline said, adding that it had launched an urgent investigation into the theft of customer data. "The personal and financial details of customers making bookings on our website and app were compromised," it said. "The breach has been resolved and our website is working normally." BA said the breach took place between August 21 and September 5 and that around 3,80,000 payment cards were compromised.
