Flight Disruptions: What Happened Today

A global outage linked to Microsoft Windows systems disrupted airport check-in operations today morning, forcing airlines to switch to manual processes. Multiple airports issued alerts to passengers and delays were reported across several flights. At Varanasi airport, passengers were informed that Microsoft Windows was experiencing major service outages globally, which had affected IT services and airport check-in systems, news agency PTI reported. In response, airlines initiated manual check-in and boarding procedures to keep operations running, resulting in longer queues, slower processing and congestion at terminals, as per the report.

SpiceJet faced disruptions in its check-in systems, resulting in delayed departures.

Varanasi airport issued alerts referring to the global Microsoft outage and various other airports saw cascading delays as airlines adopted manual boarding processes.

What Happened Yesterday?

On Tuesday, a separate outage disrupted check-in systems at multiple Indian airports after a third-party system failure involving the Amadeus software, which is widely used for airline reservations, inventory management and departure control. The disruption caused delays across several carriers before being resolved.

Air India later confirmed its systems had been fully restored and flights were back on schedule. IndiGo also faced delays due to the outage.
