NEW DELHI — India’s largest airline, IndiGo, was caught in aviation’s Slump. IndiGo cancelled more than 1,000 flights across the country, leaving passengers stranded at major travel hubs from Delhi to Mumbai on Friday.
The mass IndiGo flight cancellations, which have occurred in the wake of new, tougher pilot fatigue rules and better crew-roster planning, have forced regulators to provide temporary relief, including some night-duty limits for the carrier, until Feb. 10, as it works to return operations to normal.
How IndiGo flight cancellations turned into a fatigue-rule showdown
The disruption is being caused by India’s revamp of its Flight Duty Time Limitation (FDTL) rules, which include increasing the minimum weekly rest to 48 hours, expanding the definition of “night” and when it begins, and severely capping night landings – all aimed at reducing flight crew fatigue-related risk. Regulators started rolling out the tougher standards in July, with a second phase on Nov. 1, following more than a year of consultation and legal tussles with airlines.
IndiGo, which commands 60 per cent of India’s domestic market, had miscalculated the number of pilots it would need under the new limits and hadn’t updated its rosters in time, according to a comprehensive Reuters report. As the new rules went into effect at the height of the busy winter travel season, the airline’s network cracked under pressure, with all departures from New Delhi halted on Friday and hundreds more flights cancelled from Mumbai, Bengaluru, Hyderabad and Chennai.
Chief Executive Pieter Elbers apologised in a video statement, calling the meltdown “misjudgement and planning gaps” and admitting the disruption had “shaken” customers’ confidence in IndiGo’s punctuality. The airline has advised regulators that it will operate a truncated schedule and does not anticipate operations returning to normal until about Feb. 10, even though it hopes for a first phase of normalisation between Dec. 10 and 15.
Regulator walks a tightrope on safety as IndiGo gets rules eased.
Faced with soaring IndiGo flight cancellations and airport mayhem, the DGCA gave a reprieve to the airline ‘for one-time on a special case’ exemption under “exigencies of work pressure” from core night-operation clauses of new FDTL norms till Feb. 10. IndiGo’s “night” window is temporarily reduced by an hour and the airline can conduct as many as six night landings a week instead of two as per normal rules under the relief package, while some restrictions are also relaxed on night-time duty periods.
At the same time, the DGCA rescinded a nationwide directive that prohibited airlines from including pilots’ leave in their mandatory weekly rest, intended to give all carriers greater flexibility to complete sick rosters. Officials say the changes are closely watched and do not weaken core safety provisions, but they underscore how far the regulator is willing to stretch to get aircraft back in the air. Those details were previously reported by the Indian business daily Business Standard.
Pilot unions have lashed out at the carve-outs. In a strongly worded letter reported by The News Minute, the Airline Pilots Association of India denounced the step as “selective” and unsafe, and described it as rewarding an “artificial crisis” that the government itself has stated was engineered to exert pressure on regulators. Union leaders say passenger convenience is being prioritised over the hard-fought fatigue protections and have called for a full investigation into IndiGo’s staffing choices.
A crisis years in the making
IndiGo flight cancellations are the most visible flashpoint in a fatigue debate that has been simmering for the last two years. The DGCA quietly pushed the initial deadline for the same rest-and-duty rules to June in March 2024, after airlines cautioned that a rushed application might lead them to cancel as many as one out of every five flights, according to a contemporaneous report by NDTV.
The more stringent rules were followed after the review of pilot fatigue data was initiated when an IndiGo pilot collapsed and died before a flight in August 2023. Months later, the DGCA fined Air India 8 million rupees for violating new fatigue-management rules, reinforcing that it was a standard the regulator would apply across the industry, as reported in a Reuters archive story in March 2024.
Even before the onset of fatigue rules, IndiGo had experienced minor disruptions due to a crew crunch. In 2019, the carrier was unable to operate dozens of flights over multiple days following reports in local media of a pilot shortage, prefiguring how vulnerable a high-frequency, low-cost model reliant on tightly packed rosters can be.
Passengers suffer as IndiGo cancels more flights.
For travellers, the most recent spate of cancellations by IndiGo means missed weddings, medical appointments and job interviews, while masses at major airports have chanted slogans and lined up for hotel vouchers and ground transportation. Under the headline “travel update,” IndiGo promised automatic refunds, free rescheduling for trips through mid-December, and thousands of hotel rooms for stranded passengers, though many customers say the information flow has been patchy , and that call centres are overwhelmed.
Officials say the airline will operate a reduced schedule for several weeks while it regenerates its rosters under the new rules, and the government anticipates that on-time performance will return to normal in the days ahead. But as exemptions become increasingly tied to a turnaround plan for IndiGo, aviation analysts caution that this crisis might inform future policy on just how far India is willing to bend its pilot fatigue protections when IndiGo flight cancellations threaten to paralyse the country’s skies.
