An IndiGo flight from Chennai to Kolkata was diverted to Durgapur after a fox appeared on the runway of Netaji Subhas Chandra Bose International Airport on November 11, 2026. The pilot alerted air traffic control and executed a go-around before being rerouted to Andal Airport in Durgapur, where it landed safely.

Later that day a hijack threat was reported on an Air India flight bound for Mumbai. Investigations by the Central Industrial Security Force determined it to be a hoax. The flight was rescheduled from 10:30 a.m. to 5 p.m., and finally departed at 5:38 p.m.—nearly seven hours behind schedule.

The IndiGo flight, originally scheduled to land in Kolkata, remained delayed for over six hours before returning to the city at about 10 p.m. Passengers on both flights endured significant disruptions, with some waiting more than two and a half hours before their flights could proceed.
