Air India Flights Delayed Due To Check-In System Glitch
The incident took place after Air India's check-in systems at Delhi and various other airports faced problems due to a third-party connectivity network issue on Wednesday. The issue lasted for over an hour before the systems were finally restored.
In a post on X at 5:13 PM, Air India said that some of its flights may continue to be delayed for some time as the situation normalises progressively.
"A third-party connectivity network issue had impacted check-in systems at some airports, thereby delaying flight departures of some airlines, including Air India. The system has since been restored," the airline said.
Although the airline did not specify which airports were affected, PTI reported that the disruption hit several domestic terminals across the country. Check-in operations were reportedly halted at multiple airports for over an hour.
At Delhi’s Indira Gandhi International Airport, systems at Terminals 2 and 3 were non-functional for nearly 70 minutes. According to one of the officials familiar with the situation, the issue lasted from about 3:40 PM to 4:50 PM, PTI reported.
Following the glitch, Air India advised passengers scheduled to travel on Friday to verify their flight status on the airline’s website before heading to the airport and to factor in additional time for check-in and boarding.
By early evening, the Delhi International Airport Limited (DIAL) confirmed in a post on X that normal operations had resumed. “All systems are back to normal, and passengers may continue with their travel plans as usual,” DIAL stated in the update posted at 6:39 PM.
