Airlines resume services after global IT crash wreaks havoc

PARIS, France — Airlines were gradually coming back online Saturday after global carriers, banks and financial institutions were thrown into turmoil by one of the biggest IT crashes in recent years, caused by an update to an antivirus program.

Passenger crowds had swelled at airports on Friday to wait for news as dozens of flights were cancelled and operators struggled to keep services on track, after an update to a program operating on Microsoft Windows crashed systems worldwide.

Multiple US airlines and airports across Asia said they were now resuming operations, with check-in services restored in Hong Kong, South Korea and Thailand, and mostly back to normal in India, Indonesia and at Singapore's Changi Airport as of Saturday afternoon.

It also said it could take a few days to return to normal.

US President Joe Biden's team was talking to CrowdStrike and those affected by the glitch "and is standing by to provide assistance as needed", the White House said in a statement.
