British Airways was forced to delay flights worldwide on Thursday evening after a second IT crash in less than a week, as employees scrambled to check-in customers on backup systems.

On the same day that Russian officials imposed sanctions on British airlines, crucial IT systems were brought down.

British Airways denied it had fallen victim to a cyberattack that has prevented passengers from checking-in online and left pilots unable to access important safety systems that calculate weight and balance.

British Airways said it was investigating and working hard to resolve a technical issue. A person apologized for any hassle that had been caused.

Down Detector recorded a spike in customers reporting issues with the British Airways website on Thursday evening.

The British Airways website is offline due to an issue. British Airways switched to backup systems after their systems were taken offline.

A similar issue hit the airline for several hours on Sunday before technicians were able to fix it.

Hundreds of thousands of British Airways passengers were stranded for days after an IT contractor pulled the wrong plug at a data warehouse that was owned by the airline.

A year later, the airline revealed that the data of 380,000 passengers had been stolen. British Airways was fined the largest data protection fine ever, but regulators reduced the fine because of the impact the Pandemic had on the airline's finances.
