The news comes on the heels of a breach at Cathay Pacific exposing 9.4 million people.
British Airways said that the data breach it first reported in September is larger than previously thought. It has added an additional 185,000 victims to the official tally.
The airline said that hackers may have stolen personal data connected to an additional 77,000 payment cards, including name, billing address, email address and card payment information – including card number, expiry date and CVV.

The impacted customers were those using their air miles to book flights on the website between April 21 and July 28 of this year, and who used a payment card.
