The system resumed at 9am and along with a string of delayed flights. As a result, over 150 AI flights are likely to face delays of about two hours till 8.30pm.
Incidentally, SITA, a leading air transport IT specialist, says the snag happened during maintenance of the system and affected only Air India.
Thousands of passengers are stuck at big airports like Delhi and Mumbai as the affected system controls passenger and baggage check-in. AI is rescheduling flights to clear the backlog and flight delays of about two hours are expected.
After supervising the situation at Delhi Airport, AI chairman Ashwani Lohani said that SITA system has resumed at 8.45am. Due to this, till 10am, 85 of our flights have been delayed.
The ripple effect of the delays will be felt mainly on domestic flights till tonight. As of now, we have rescheduled 18 flights for today and cancelled some.
International flights will not face much impact barring a few like the Shanghai departure being delayed by 1.5 hours. The afternoon departures for Europe will leave with a delay of 15 to 30 minutes. It was a very major software disruption that we experienced.
AI and AI Group including AI Express and Alliance Air has 470 and 674 daily flights, respectively. AI officials rushed to airports to handle the situation as large number of passengers were stranded at high hubs.
Globally airlines experience such outages. We regret the inconvenience caused to passengers by the snag in SITA system. Some of our transit passengers like those coming from Kathmandu, Bangkok, Singapore to Delhi may miss their connections.
We have made hotel accommodations for such passengers. The change and reschedule charges have been waived for passengers affected by this major SITA outage, Lohani said.
Air India server crashed since 3.30 am. All flights cancelled. Thousands of passengers stranded at the airport. Nobody knows what is happening. Don’t go to the airport without confirming.

The snag affected functions like check-in, both at airport counters and web check-in, that delayed flights.
SITA spokesman Julius Baumann said SITA experienced a complex system issue during server maintenance early this morning, which resulted in operational disruption to Air India flights. We have now fully restored services at all airports where Air India were affected.
Our priority remains, as always, to ensure a stable system where customers can conduct business efficiently and effectively, and we are undertaking a full investigation to understand the root cause and prevent a recurrence.
We deeply regret the inconvenience this has caused to the airline and their customers owing to this disruption.
