British Airways has warned customers that around 380,000 card payments on its website and app were compromised during a 15-day data breach.

The airline said “criminal activity” had exposed the personal and financial details of customers who made bookings on its website or app from just before 11pm on August 21 until 9.45pm on Wednesday. The company’s chief executive, Álex Cruz, has apologised and vowed to compensate customers after the breach.
