Check-in systems at several airports across the country faced technical issues on Wednesday morning due to a system outage, resulting in delays to multiple flights, news agency PTI reported, quoting a source.
At least four airlines - IndiGo, SpiceJet, Akasa Air and Air India Express - were affected, with some carriers switching to manual check-in and boarding procedures to manage passenger flow, the source added.
A message displayed for passengers at Varanasi airport attributed the disruption to a "Microsoft Windows outage", stating that "IT services/check-in systems at airports are impacted". It also said airlines had moved to manual processes temporarily.
However, Microsoft denied any such problem, calling the claim "factually incorrect".
"This is factually incorrect. No outages reported on Windows," the tech giant said in response to a PTI query.
Real-time outage tracking platform Downdetector also showed no reports of a Windows-related disruption.
Meanwhile, the Delhi International Airport Ltd (DIAL) said some domestic carriers were experiencing "operational challenges", PTI reported.
"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 of the cause of the outage were not immediately available.
Indigo issues statement amid cancellations and delays
Amid the glitches, IndiGo has issued a statement on the cancellations and delays.
IndiGo, which saw several cancellations and delays nationwide, attributed the disruptions to "technology issues, airport congestion, and operational requirements".
In a statement, the airline said, "We have had several unavoidable flight delays and some cancellations in the past few days due to various reasons including technology issues, airport congestion, and operational requirements. Our teams are working diligently to ensure that operations normalise as soon as possible. Furthermore, we are offering alternate flight options or refunds to affected customers, as applicable. We regret the inconvenience caused to our valued customers due to these disruptions."
The carrier also advised passengers to check their latest flight status before heading to the airport.
"We request customers to check the latest flight status at https://www.goindigo.in/check-flightstatus.html before heading to the airport, to help us minimise inconvenience," it added.
Across major airports, passengers reported long queues and delays as airlines continued to work with airport authorities to restore normal operations.
