In this Special Report, India Today’s Shreya Chatterjee tracks the escalating IndiGo airlines crisis as 650 flights stand cancelled on Sunday, December 7. The Directorate General of Civil Aviation (DGCA) has issued a show-cause notice to IndiGo CEO Pieter Elbers, demanding an explanation within 24 hours for the massive disruptions. Chatterjee notes that ‘the kind of effort that the airlines is putting is not enough to meet the woes that the people… have already faced’. The programme highlights the chaos at airports including Delhi and Bengaluru, with the Parliamentary Committee also summoning airline officials. The crisis, now in its sixth day, has seen the Prime Minister’s Office keeping a close watch, while the government has prohibited airlines from charging above fixed fare limits. Anirban Sinha Roy reports from Kolkata, where passengers are stranded due to rescheduled and cancelled flights.
