‘Strategic mistake’? Hundreds of IndiGo flights canceled as new pilot duty norms kick in - top things to know about new DGCA roster rules

IndiGo, India’s largest airline, has delayed or cancelled hundreds of flights over the past two days as it struggles with new pilot rest and duty-hour norms, even a month after the aviation regulator implemented them. The airline, which operates around 2,300 domestic and international flights each day, said on Wednesday that a "multitude of unforeseen operational challenges" had severely disrupted its network over the past two days, and apologised to passengers for the inconvenience. It added that the disruptions are expected to persist for the next 48 hours. On Tuesday, just three out of 10 flights departed on schedule, despite punctuality being a key service promise. Almost 62 per cent of the 1,232 flights IndiGo cancelled in November were attributed to "crew constraints".
