New Delhi: IndiGo, India’s largest airline, faced major operational turbulence this week after failing to prepare for new pilot-fatigue regulations issued by the Directorate General of Civil Aviation (DGCA). The stricter rules—designed to improve flight safety—took effect in phases through 2024, with the latest implementation on November 1. IndiGo has acknowledged that inadequate roster planning led to widespread cancellations and delays.

Below are the key DGCA rules that affected IndiGo’s operations:

1. Longer Mandatory Weekly Rest

Weekly rest for pilots has been increased from 36 hours to 48 hours.

The government says the extended break is essential to curb cumulative fatigue. This rule remains in force despite the current crisis.

2. Cap on Night Landings

Pilots can now perform only two night landings per week—a steep reduction from the earlier limit of six.

Night hours, defined as midnight to early morning, are considered the least alert period for pilots.

Given the disruptions, this rule has been temporarily relaxed for IndiGo until February 10.

3. Reduced Maximum Night Flight Duty

Flight duty that stretches into the night is now capped at 10 hours.

This measure has also been kept on hold for IndiGo until February 10 to stabilize operations.

4. Weekly Rest Cannot Be Replaced With Personal Leave

Airlines can no longer count a pilot’s personal leave as part of the mandatory 48-hour rest.

Pilots say this closes a loophole that previously reduced actual rest time.

Currently, all airlines are exempt from this rule to normalise travel.

5. Mandatory Fatigue Monitoring

Airlines must submit quarterly fatigue reports along with corrective actions to DGCA.

This system aims to create a transparent fatigue-tracking framework across the industry.

The DGCA has stressed that these rules were crafted to strengthen flight safety and align India with global fatigue-management standards. The temporary relaxations are expected to remain until February 2025, giving IndiGo time to stabilise its schedules and restore normal air travel.

Mangaluru: Chaos erupted at Mangaluru International Airport (MIA) after IndiGo flight 6E 5150, bound for Mumbai, was repeatedly delayed and ultimately cancelled, leaving around 100 passengers stranded overnight. The incident highlights the ongoing country-wide operational disruptions affecting the airline, largely due to the implementation of new Flight Duty Time Limitations (FDTL) norms for crew.

The flight was initially scheduled for 9:25 PM on Tuesday but was first postponed to 11:40 PM, then midnight, before being cancelled around 3:00 AM. Passengers expressed frustration over last-minute communication and the lack of clarity, with elderly and ailing travellers particularly affected. “Though the airline arranged food, there was no proper communication, leaving us confused,” said one family member.

An IndiGo executive at MIA cited the FDTL rules, designed to prevent pilot fatigue by limiting crew working hours, as the cause of the cancellation. While alternative arrangements, including hotel stays, were offered, about 100 passengers chose to remain at the airport, creating tension. A replacement flight was arranged but also faced delays due to the same constraints, finally departing for Mumbai around 1:45 PM on Wednesday. Passengers either flew, requested refunds, or postponed their travel.

The Mangaluru delay is part of a broader crisis for IndiGo. The airline has been forced to make “calibrated schedule adjustments”—a euphemism for widespread cancellations and delays—after stricter FDTL norms came into effect on November 1.

While an IndiGo spokesperson acknowledged unavoidable flight disruptions due to technology issues, operational requirements, and the updated crew rostering rules, the DGCA has intervened, summoning senior airline officials to explain the chaos and outline corrective measures.

The ripple effect has been felt across the country, with major hubs like Bengaluru and Mumbai reporting numerous cancellations. The Mangaluru incident underscores the systemic operational strain currently confronting India’s largest carrier, leaving passengers nationwide grappling with uncertainty and delays.

New Delhi, Dec 5: IndiGo CEO Pieter Elbers issued a public apology this evening after more than a thousand flights were cancelled today, making it the "most severely impacted day" in terms of cancellations. The biggest airline of the country cancelled "more than half" of its daily number of flights on Friday, said Elbers. He also said that even though the crisis will persist on Saturday, the airline anticipates fewer than 1,000 flight cancellations.

"Full normalisation is expected between December 10 and 15, though IndiGo cautions that recovery will take time due to the scale of operations," the IndiGo CEO said. 

IndiGo operates around 2,300 domestic and international flights daily.

Pieter Elbers, while apologising for the major inconvenience due to delays and cancellations, said the situation is a result of various causes.

The crisis at IndiGo stems from new regulations that boost pilots' weekly rest requirements by 12 hours to 48 and allow only two night-time landings per week, down from six. IndiGo has attributed the mass cancellations to "misjudgment and planning gaps".

Elbers also listed three lines of action that the airline will adopt to address the issue.

"Firstly, customer communication and addressing your needs, for this, messages have been sent on social media. And just now, a more detailed communication with information, refunds, cancellations and other customer support measures was sent," he said.

The airline has also stepped up its call centre capacity.

"Secondly, due to yesterday's situation, we had customers stranded mostly at the nation's largest airports. Our focus was for all of them to be able to travel today itself, which will be achieved. For this, we also ask customers whose flights are cancelled not to come to the airports as notifications are sent," the CEO said.

"Thirdly, cancellations were made for today to align our crew and planes to be where they need to start tomorrow morning afresh. Earlier measures of the last few days, regrettable, have proven not to be enough, but we have decided today to reboot all our systems and schedules, resulting in the highest numbers of cancellations so far, but imperative for progressive improvements starting from tomorrow," he added.

As airports witnessed chaotic scenes, the Directorate General of Civil Aviation (DGCA) stepped in to grant IndiGo a temporary exemption from stricter night duty rules for pilots. It also allowed substitution of leaves with a weekly rest period. 

Civil Aviation Minister Ram Mohan Naidu has said a high-level inquiry will be ordered and accountability will be fixed.
