In a post on X, Air India also said that some of its flights may continue to be delayed for some time as the situation normalises progressively.

At the Delhi airport, the check-in systems were down at terminals T2 and T3 for around 70 minutes from 3.40 pm till 4.50 pm, one of the sources said.

"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.

Air India also asked passengers flying with the airline on Wednesday to check their flight status on its website before heading to the airport and allow extra time for their journey.
