A widespread Microsoft outage has affected flight services in India, with SpiceJet reporting cancellations and delays at Delhi airport on Friday morning. Other airlines have so far said their operations remain unaffected, but have urged passengers to stay updated on possible changes.

SpiceJet cancelled three flights scheduled to depart from Delhi, including services to Pune, Leh and Mumbai. Two other flights — from Delhi to Darbhanga and Delhi to Mumbai — were delayed.

The disruption has prompted airlines to step up monitoring as they assess whether the technology failure could affect passenger services or operational systems.

Airlines ask passengers to check flight status

Air India said it was tracking the Microsoft outage but had not experienced any disruption to its flight operations. The airline also confirmed that its communication systems were working normally.

To prevent interruptions in passenger correspondence, Air India has temporarily redirected email traffic through alternative channels. It said customer emails were being handled within its usual response window of 24 hours.

IndiGo and Akasa Air have also issued passenger advisories, asking travellers to monitor flight-related notifications and check for updates before heading to the airport.

Delhi Airport has separately cautioned passengers to verify their flight information ahead of their journeys.

Microsoft investigates disruption to email and Teams

The airline advisories follow a major disruption to Microsoft's services that began on Thursday. Users across several regions reported problems accessing Outlook and other applications within the company's software ecosystem, including Teams.

Microsoft acknowledged the issue and said it was investigating reports of users being unable to access Exchange Online mailboxes through different connection methods in the Americas.

The company did not immediately identify the precise cause of the disruption but said it was testing a possible fix.

In an update posted on X through its Microsoft 365 Status account, the company said it was pursuing multiple measures to minimise the impact on users.

With airlines continuing to monitor the situation, passengers have been advised to rely on official airline and airport updates for the latest information about their journeys.
