Sabre’s SynXis hotel reservations system suffered a breach in 2016-17 which saw unauthorised access to credit card details, including card security codes.

Speaking at German travel trade show ITB in Berlin, Anderson said: “We had a data breach 24 months ago. It was a day of awakening for us.”

He said: “These problems are not going away. Cyber threats are increasing.” But he insisted: “Ultimately, we will see significant consumer confidence in this, in how data is safely stored.”
