Airlines have suspended flights over Iranian and Iraqi airspace following a sudden closure of Iranian airspace on Wednesday-Thursday night, resulting in cancellations and rerouting of several flights between India and the West. Air India cancelled multiple flights to New York and Newark, while an IndiGo flight from Baku to Delhi returned to Azerbaijan after being unable to cross Iranian airspace. Airlines are now taking longer alternative routes, which may lead to delays and additional stops. Despite a brief resumption of normal operations in Iranian airspace, many carriers continue to avoid the region due to safety concerns. The situation remains fluid, with ongoing security issues in Iran's urban centers potentially causing further disruptions to airport operations.
