International Airlines Group (IAG), owner of British Airways, has revealed the possibility that an additional 185,000 customers’ data may have been compromised.

British Airways confirmed  77,000 customers’ payment cards details including name, billing address, email address, payment information including card number, expiry date and security codes had potentially been compromised, plus an additional 108,000 without the security code.

British Airways has made it very clear the airline will compensate any customers for direct financial losses incurred as a result of the breach in data security.

The airline also confirmed that only those customers who made reward bookings between April 21 and July 28 and who used a payment card could have been affected.

The airline also confirmed that this was the most serious attack on its website and app.

The attack took place only 15 months after its computer system failed at London Heathrow Airport, stranding 75,000 passengers during a holiday weekend.
