IndiGo Airlines Faces Major Operational Disruption Due to New Flight Duty Regulations

New Delhi: On Thursday, IndiGo Airlines, India’s largest carrier, encountered a significant operational setback as it implemented the final phase of new Flight Duty Time Limitation (FDTL) regulations. This led to widespread cancellations and delays, stranding passengers at various airports and impacting the operations of other airlines.

Understanding the FDTL Regulations

The updated FDTL norms, which aim to enhance flight safety by managing pilot fatigue, were mandated by court directives and rolled out in two phases, with the final phase taking effect on November 1, 2025. These regulations are designed to ensure that pilots receive adequate rest and that operational safety is prioritized.

Flight Cancellations and Delays

Reports indicate that on Thursday alone, IndiGo cancelled over 550 flights, a staggering number considering the airline typically operates around 2,300 flights daily. This led to a dramatic decrease in punctuality, with just 19.7% of flights arriving on time—a sharp decline from 35% the previous day and 50% lower than a couple of days prior.

Impact by City

Kolkata

Kolkata’s Netaji Subhash Chandra Bose International Airport was one of the hardest hit. From midnight to 6 PM on December 4, IndiGo cancelled and delayed 112 flights. By late evening, that number surged to 168, with 11 flights cancelled and 64 delayed on arrival and 11 cancelled and 82 delayed on departure.

Ahmedabad

In Ahmedabad, the situation was also challenging, with at least 27 flights impacted by noon on December 4. This included 10 domestic arrivals, 14 domestic departures, and several international flights.

New Delhi, Hyderabad, and Bengaluru

New Delhi saw the cancellation of 77 arriving and 86 departing flights on Thursday, while Hyderabad faced cancellations affecting 37 arrivals and 42 departures. Bengaluru Airport recorded 70 flight cancellations, compounding frustrations for passengers.

Ripple Effect on Other Airlines

The operational crisis at IndiGo not only affected its own flights but also created congestion and delays for other airlines at airports, notably in Pune. Passengers from different carriers were stuck as IndiGo flights monopolized multiple boarding bays, causing widespread schedule disruptions.

Anticipated Continued Disruptions

In light of the ongoing issues, IndiGo has informed the Directorate General of Civil Aviation (DGCA) that further flight cancellations could persist for the next two to three days. Operations are expected to stabilize only by February 10, 2026. As a result, the airline is requesting temporary relief from certain FDTL regulations to return to normalcy sooner.

Reasons for Seeking Relaxation

IndiGo’s request for exemptions from certain requirements regarding its A320 operations highlights the ongoing challenge of crew shortages. The airline reported a current fleet of 2,357 captains and 2,194 first officers for December, down from higher numbers needed following the implementation of the second phase of FDTL rules.

Government Response

In response to the disruptions, Civil Aviation Minister K. Rammohan Naidu convened an emergency meeting to address the situation. The minister urged IndiGo to normalize operations promptly and instructed the airline to prevent any spike in airfares resulting from these cancellations and delays.

During this meeting, IndiGo presented data illustrating the reasons behind the disruptions. Challenges with crew management and unforeseen seasonal weather impacts were cited among the primary factors affecting operational stability.

The situation underscores the complexities airlines face when adjusting to new regulations and the broad impact these changes can have on air travel.
