The Air France-KLM group's databases are monitored in real time to identify and prevent any fraudulent access. There has been no hacking of airlines group databases.
An e-mail sent to the customers before their trip contains a link to the check-in process on the airlines' commercial websites. Fraudulent use of this link would under no circumstances allow access to data other than that of the current reservation. Customer profile information, including sensitive information such as bank details, is fully protected.
IT teams immediately took the necessary steps and the update of the link sent to customers as part of the check-in process is effective.
