British Airways has released details of the recent theft of customer data from its website and mobile app.

The carrier said that the breach took place over 15 days between 2258 on August 21 and 2145 on September 5, with around 380,000 financial transactions believed to have been compromised.

The theft included personal and financial details of customers making bookings on ba.com and the airline’s app during this time, although travel and passport details were not affected.

BA says it is contacting affected customers, and has taken out full page ads in several newspapers to apologise for the breach.

The carrier is advising all customers who believe they may have been affected to contact their bank or credit card provider and follow recommended advice.

When a member of the Business Traveller team (who owns a BA Amex card) did so this morning, they were greeted with a recorded message advising them that the provider was aware of the potential breach, and that no further action was required at this time.

BA’s website has a page with further information on the breach here, where it confirms that “Every customer affected will be fully reimbursed and we will pay for a credit checking service”.
