Additionally, British Airways issued a public apology for the disruptions and inconveniences caused to passengers during the crisis.

Estimates suggest that the incident cost the airline approximately £80 million ($102 million) in expenses, including compensation for affected passengers and other related costs. This event underscored the importance of robust IT systems and disaster recovery plans for organizations heavily reliant on technology infrastructure.


The British Airways IT failure in May 2017 stands as a stark reminder of the potential consequences when critical systems fail. The incident led to extensive flight cancellations, delays, and challenges for passengers, prompting the airline to conduct an investigation and apologize for the disruption caused.
