We are investigating, as a matter of urgency, the theft of customer data between 22:58 BST August 21 2018 until 21:45 BST September 5 2018 from our website, ba.com, and our mobile app.
The stolen data included personal and financial details of customers making bookings and changes on ba.com and the airline’s app. The data did not include travel or passport details.
The theft has been reported to the authorities and our website is now working normally.
If you believe you may have been affected because you made a booking or paid to change your booking with a credit or debit card on ba.com or the mobile app between 22:58 BST August 21 2018 until 21:45 BST September 5 2018, we recommend you contact your bank or credit card provider and follow their advice.
We understand that this incident will cause concern and inconvenience. We are contacting all affected customers to say sorry, and we will continue to update them in the coming days.
Customers should also be aware that fraudsters may be claiming to be British Airways and attempt to gather personal information by deception (known as 'phishing').
We will not be contacting any customers asking for payment card details and any such requests should be reported to the police and relevant authorities.
