A Delhi-bound IndiGo flight from Tbilisi, Georgia, managed to cross Iranian airspace just minutes before Iran abruptly closed its skies, according to aviation tracking data and airline sources—highlighting the disruption caused by the sudden shutdown to global air travel.IndiGo flight 6E1808 took off from Tbilisi late Wednesday night, flew over Iran around 2:35 am on Thursday, and touched down in Delhi at 7:03 am, as per live data from Flightradar24.The aircraft is thought to have been the final non-Iranian commercial flight airborne before Iran’s aviation authorities issued a Notice to Airmen (NOTAM) announcing the immediate closure of most of the country’s airspace.The sudden restriction, enforced amid escalating protests across Iran that began on December 28, brought most flight operations to a standstill. Only a handful of authorised services were permitted, forcing airlines worldwide to quickly reroute, delay, or cancel flights.
