An IndiGo flight from Georgia's Tbilisi to Delhi was reportedly the last non-Iranian aircraft in the air before Tehran abruptly closed its airspace on Thursday
amid escalating unrest. Following the closure, IndiGo, Air India and SpiceJet have warned passengers of potential flight disruptions. Iran issued a Notice to Airmen (NOTAM) early Thursday, shutting most flights except a limited number of approved international services. Flight-tracking data showed skies over Iran and Iraq quickly emptying ahead of the directive. Iran has extended its airspace closure as tensions persist amid the regime’s violent crackdown on anti-Khamenei protests, which have claimed more than 2,400 lives in the two weeks since unrest erupted on December 28. According to live flight-tracking site Flightradar24, IndiGo flight 6E1808 departed Tbilisi at 11:29 am on Wednesday and landed in Delhi at 7:03 am on Thursday, passing over Iranian airspace at around 2:35 am. Following Iran’s sudden airspace closure, IndiGo, Air India and SpiceJet have warned of potential flight disruptions. Passengers on affected international flights have been urged to check their flight status and consider alternative travel options. IndiGo said that some of its international flights have been impacted, adding that it was working to support affected customers by offering rebooking options or refunds.

Iran closed its airspace to commercial flights without explanation in the early hours of Thursday. Before the extension, the airspace had already been restricted for more than four hours, forcing international airlines to divert routes to the north and south of the country.
Iran had previously shut its airspace during the 12-day conflict with Israel in June, as well as during exchanges of fire with Israel amid the Israel-Hamas war.
