Airline check-in staff at Singapore’s Changi Airport along with several other major gateways were forced to manually process guests yesterday when a mass outage affected systems around the word.

The technical issue was discovered at 5.30pm (Singapore time) on Thursday and lasted for around three hours affected check-in services at several airports including Changi, Charles de Gaulle Airport in Paris and the Reagan Airport in Washington DC, Today Online reported.

It’s unclear how many air services were disrupted by the power outage, however, according to several social media posts, the disruption created significant queues in departure halls.

According to Changi Airport’s latest Facebook post, the system has since returned online and flights are back to operating as scheduled.
