India’s largest airline, IndiGo, has cancelled more than 550 flights nationwide for the fourth consecutive day, severely disrupting travel plans for thousands of passengers. The cancellations affected major airports including Mumbai, Bengaluru, Hyderabad, Kolkata, Chennai, and Goa. The disruption stems from newly implemented crew rostering and flight duty time limitation (FDTL) regulations, which have increased mandatory rest periods and reduced the number of permitted night landings. With a shortage of pilots and crew, IndiGo has struggled to maintain its schedule. The airline stated that it is taking all necessary measures to restore normal operations and expects the situation to stabilize within 48 hours. However, cancellations may continue for the next few days, and IndiGo plans to reduce flight operations from December 8. Passengers have faced severe inconvenience, with reports of thousands of unclaimed suitcases piling up at Delhi airport terminals.
