IndiGo on Friday said its email support services have been impacted by the Microsoft service disruption.
In a post on X, the country's largest airline said all other support channels remain available.
"Due to a global Microsoft service disruption, our email support services are currently impacted, and we may not be able to receive your emails," the carrier said.
Air India, in a post on X, said it was closely monitoring the
ongoing Microsoft outage and that its flight operations remain unaffected.
There is currently no impact on any of our communication channels, the airline said.
"To ensure seamless support, we have temporarily rerouted our emails so that every message continues to reach us without interruption, and we are responding to all emails within our usual 24-hour timeline," it said.
Further details could not be immediately ascertained.
