Overview
Air France and KLM Royal Dutch Airlines have confirmed a second major data breach in just over two years, and UK passengers are among those affected.
The July 2025 incident involved unauthorised access to a third-party customer service platform. Attackers are believed to have accessed names, contact details, Flying Blue membership numbers and tier status, and even subject lines from customer service emails.
Air France and KLM Royal Dutch Airlines are owned by the same company, Air France-KLM. While the Airline claims that more sensitive information, such as passwords, passport numbers, booking details, and credit card numbers, were not taken, the stolen data could still be used to launch targeted phishing scams.
Those affected by this breach should have received a data breach notification letter/email.
We are monitoring the situation closely. Register your interest and we’ll keep you updated if one of our regulated UK partner law firms is able to take this claim forward.
