New Delhi | Check-in systems at various airports faced issues on Wednesday morning due to a system outage, according to a source.
The source added that some flights have been delayed due to the issues.
While a message displayed for passengers at Varanasi airport cited Microsoft Windows outage, the tech company denied any such outage, calling it “factually incorrect”.
Real time outage monitoring website Downdetector too did not reflect any user report of disruption.
A message for the passengers at the Varanasi airport, however read, "Microsoft Windows reports major service outages globally. IT services/ check in systems at airports are impacted".
According to the message, airlines have implemented manual check in and boarding procedures.
At least four airlines -- IndiGo, SpiceJet, Akasa Air and Air India Express -- have been affected, it said.
When contacted, Microsoft said there was no outage on Windows.
"This is factually incorrect. No outages reported on Windows," Microsoft said in response to a PTI query.
There were no immediate comments from the airlines.
"Some domestic airlines are currently experiencing operational challenges, which may lead to delays or schedule challenges.
"Our on-ground teams are diligently working with all stakeholders to ensure a seamless and efficient passenger experience," DIAL said in a post on X at 7.40 am.
Specific details could not be immediately ascertained.
