On Friday (19 July), a Windows update caused a worldwide IT outage, crashing several systems including those at airports.
Changi Airport was not spared, with airlines resorting to carrying out manual check-ins for passengers, reported The Straits Times (ST).
The airport has since updated that most check-in operations for passengers have returned to the status quo.
On Saturday (20 July) at 6.14am, Changi Airport shared via a Facebook post that check-in operations for most airlines affected by the IT outage have “returned to normal”.

However, a small number of airlines still require manual check-ins for passengers.
“Changi Airport is supporting these airlines with additional resources,” the airport said. “For passengers affected, we seek your patience and understanding.”
In response to a query on the names of the airlines that still required passengers to manually check-in, Changi Airport said:
We are unable to advise on specific airlines check in situations.

ST reported that only one out of 490 scheduled flights from Singapore on 19 July was cancelled.
More than 40 experienced delays, however, as a result of the outage.
Affected airlines included Scoot, Jetstar, AirAsia, and Cebu Pacific Air.
Flights across the world, such as in the US and Germany, experienced similar delays and cancellations.
Data from aviation analytics company Cirium showed that airlines had to cancel about 1,390 flights globally, as of 6pm in Singapore.
The widespread IT outage was the result of a software update by cybersecurity company CrowdStrike, one of the world’s most popular cybersecurity firms.
CrowdStrike Chief Executive Officer George Kurtz said on X that there had been a “defect” in a “single content update” for Windows hosts.
“The issue has been identified, isolated and a fix has been deployed,” he said.
