Mumbai: Shares of InterGlobe Aviation, the parent company of IndiGo Airlines, slumped more than 6.5 per cent in early trade on Monday amid mounting scrutiny over the carrier’s ongoing flight disruptions. The stock hit an intra-day low of ₹5,015 on the BSE, before recovering partially to ₹5,159.50 around 9:45 a.m., still down 3.93 per cent.

The sharp sell-off followed the Directorate General of Civil Aviation’s (DGCA) decision to extend the deadline for IndiGo CEO Pieter Elbers to respond to a show-cause notice linked to the airline’s operational breakdown.

The aviation regulator issued the notice to IndiGo’s accountable manager on Sunday, just a day after sending a similar directive to the CEO. The DGCA stated that the large-scale cancellations over the past week caused widespread inconvenience for passengers across multiple airports.

According to the regulator, the disruptions were triggered by IndiGo’s inadequate planning for the rollout of the revised Flight Duty Time Limitations (FDTL) rules, which mandate maximum duty hours and minimum rest periods for flight crew. The DGCA said the airline’s “large-scale operation failures” point to lapses in planning, oversight and resource management.

IndiGo’s accountable manager has been given 24 hours to justify why enforcement action should not be taken. If the airline fails to respond in time, the DGCA has said it will proceed based on available information.

Despite regulatory pressure, IndiGo said on Sunday that it has restored 95 per cent of its network and is operating about 1,500 flights daily. The airline expects full stabilisation by December 10 with improved on-time performance and reduced cancellations.

However, more than 220 flights were cancelled across major airports at the time of reporting, adding to the frustration of thousands of stranded passengers.
