The Directorate General of Civil Aviation (DGCA) on Wednesday sought an explanation from IndiGo over the sharp decline in its operational performance in November. The airline recorded over 1,200 flight cancellations during the month, along with widespread delays, prompting the aviation regulator to closely scrutinise its operations.

The decision came on the day when the country's largest airline cancelled more than 100 flights at various airports, and scores of services were delayed as it grappled with significant operational disruptions, mainly due to crew shortage, and announced calibrated schedule adjustments. The cancellation list involved 38 flights at Delhi Airport, 33 at the Mumbai Airport, and 14 at the Ahmedabad Airport.

The DGCA is currently investigating the situation and evaluating measures along with the airline to reduce cancellations and delays, in order to minimise inconvenience being caused to passengers. "IndiGo has been asked to report to DGCA, Headquarters, to present the facts leading to the current situation, along with plans to mitigate the ongoing delays & cancellations," it said
