IndiGo has submitted a revised winter flight schedule to the Directorate General of Civil Aviation (DGCA) after the aviation regulator directed the carrier to reduce its operations by 5% across all sectors. The revised schedule was due on 10 December, following growing concerns over IndiGo’s ability to operate its previously approved capacity without significant disruptions.

With the revised schedule now submitted, IndiGo is expected to reduce weekly flights by 1,501 services, cut approximately 215 flights per day, bring daily operations down from 2,145 flights to about 1,930, rationalise frequencies on high-density and high-disruption routes and avoid single-flight operations on routes where a cancellation would leave passengers without alternative options.

Officials said the aim is to stabilise on-time performance, reduce cascading delays, and ensure better resource deployment including aircraft availability, crew utilisation, and contingency buffers.

The DGCA’s directive came after a detailed review of IndiGo’s operating performance for November 2025. According to the regulator, IndiGo had approval to operate 64,346 flights during the month.

However, operational data showed that the airline was only able to fly 59,438 flights, while 951 flights were cancelled, raising questions about system preparedness, crew availability, and overall stability during the high traffic winter period.

With DGCA reviewing the newly submitted winter schedule, passengers flying IndiGo in the coming weeks may experience minor timing adjustments, change of frequency on specific routes, re-accommodation on alternate services and increased advisories.

Both IndiGo and the DGCA have urged passengers to maintain buffer time for onward connections during the winter season, when weather disruptions are common.

The DGCA is now examining the revised roster and may issue additional instructions depending on the airline’s operational readiness and performance over the next few days.

Given the scale of disruptions, the Ministry has instructed the DGCA to keep IndiGo under continuous monitoring, with the possibility of further corrective action if operational performance does not improve.

Further details are awaited.
