Normalcy in the check-in system at the Kolkata airport was restored after being disrupted for nine hours on Monday, inconveniencing scores of passengers.
A tweet by Kolkata Airport thanked passengers and other stakeholders for their patience.
"The Local Area Network has been restored at around 0230hrs. We thank our passengers, airlines and all the stakeholders for the patience and cooperation," it said.
Five Kolkata-bound flights were also diverted Monday evening owing to bad weather in the city.
The AAI owns and manages more than 100 airports - including the Netaji Subhash Chandra Bose International (NSCBI) Airport in Kolkata.
Around 30 flights were delayed by an average of 20-25 minutes as boarding passes had to be issued manually.
The flyers took to social media to report about the chaos at the airport.
