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.

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.

Domestic carrier IndiGo has cancelled over 180 flights from three major airports — Mumbai, Delhi and Bengaluru — on Thursday, December 4, as the airline struggles to secure the required crew to operate its flights in the wake of new flight-duty and rest-period norms for pilots.

While the number of cancellations at Mumbai airport stands at 86 (41 arrivals and 45 departures) for the day, at Bengaluru, 73 flights have been cancelled, including 41 arrivals, according to a PTI report that quoted sources.

"IndiGo cancelled over 180 flights on Thursday at three airports-Mumbai, Delhi and Bengaluru," the source told the news agency.

Besides, it had cancelled as many as 33 flights at Delhi airport for Thursday, the source said, adding, "The number of cancellations is expected to be higher by the end of the day."

The Gurugram-based airline's On-Time Performance (OTP) nosedived to 19.7 per cent at six key airports — Delhi, Mumbai, Chennai, Kolkata, Bengaluru and Hyderabad — on December 3, as it struggled to get the required crew to operate its services, down from almost half of December 2, when it was 35 per cent.

"IndiGo has been facing acute crew shortage since the implementation of the second phase of the FDTL (Flight Duty Time Limitations) norms, leading to cancellations and huge delays in its operations across the airports," a source had told PTI on Wednesday.

Chaos continued at several major airports for the third day on Thursday because of the cancellations.

A spokesperson for the Kempegowda International Airport (KIA) in Bengaluru said that 73 IndiGo flights had been cancelled on Thursday.

At least 150 flights were cancelled and dozens of others delayed on Wednesday, airport sources said, leaving thousands of travellers stranded, according to news agency Reuters.

The Directorate General of Civil Aviation (DGCA) has said it is investigating IndiGo flight disruptions and has asked the airline to submit the reasons for the current situation, as well as its plans to reduce flight cancellations and delays.

It may be mentioned here that the pilots' body, Federation of Indian Pilots (FIP), has alleged that IndiGo, despite getting a two-year preparatory window before the full implementation of new flight duty and rest period norms for cockpit crew, "inexplicably" adopted a "hiring freeze".

The FIP said it has urged the safety regulator, the DGCA, not to approve airlines' seasonal flight schedules unless they have adequate staff to operate their services "safely and reliably" in accordance with the New Flight Duty Time Limitations (FDTL) norms.

In a letter to the DGCA late on Wednesday, the FIP urged the DGCA to consider re-evaluating and reallocating slots to other airlines, which have the capacity to operate them without disruption during the peak holiday and fog season if IndiGo continues to "fail in delivering on its commitments to passengers due to its own avoidable staffing shortages."
