The prolonged US-Iran conflict has taken a heavy toll on Indian airlines, with around 26,000 international flights cancelled till July 20 as carriers continue to grapple with airspace restrictions across the Middle East.Apart from the large-scale cancellations, airlines have also faced flight diversions and delays, while longer flying routes have increased fuel consumption and operating expenses. The government said carriers are also suffering significant revenue losses but are taking steps to keep services running.Responding to questions from Congress MP Anto Antony in the Lok Sabha, minister of state for civil aviation Murlidhar Mohol said the conflict, which began in late February, has severely disrupted international operations because of restrictions on the use of airspace.“The US-Iran conflict has significantly disrupted international flight operations due to airspace restrictions leading to widespread cancellations (approx. 26,000 flights by Indian carriers till 20 July 2026), along with considerable diversions and delays across airlines and airports,” Mohol said in a written reply.The minister said the Directorate General of Civil Aviation (DGCA) has issued several advisories to ensure the safety of passengers, crew and aircraft in view of the risks arising from the conflict in the region.The disruption has also translated into higher costs for airlines as flights are being operated on longer routes.“As informed by Indian carriers, re-routing of flights has led to increased flight durations and higher fuel consumption, resulting in additional operational costs for airlines. The extent of such costs depends on route diversion, duration and prevailing fuel prices,” Mohol said.He added that the financial impact has gone beyond higher operating costs.“Further, as informed, airlines are incurring significant revenue losses due to the ongoing crisis. Airlines are, however, taking necessary measures to mitigate the impact while ensuring continuity of operations,” the minister said.The airline industry has been dealing with elevated fuel costs and operational constraints since the conflict erupted in late February, with airspace curbs in the Middle East continuing to affect international flight schedules.
