IndiGo staff had to move to manual bookings due to the server glitch

IndiGo passengers had a difficult time on Monday after 29 flights were delayed for more than half-an-hour at the Bengaluru airport due to a server glitch.

The reservation system, which conked out at 4.29 am, could be restored only at 5.07 am, IndiGo said in a statement.

"A technical glitch was observed for about half an hour early this morning from 4.29 am to 5.07 am. This affected just 29 flights with an average delay of less than 30 minutes approximately," IndiGo said in a late evening statement.

Earlier, an airline spokesperson said 63 flights were affected due to the conking out of the server.

As the IndiGo staff moved to manual bookings due to the server glitch, it resulted in long queues at the airline's check-in counters across the airport, according to sources.

"The server was fully restored and functioned smoothly afterwards. We regret the inconvenience caused to our passengers," IndiGo said in the statement.
