India’s largest airline, IndiGo, faced another day of widespread disruption on Thursday as hundreds of passengers across major cities were left stranded due to continued flight cancellations triggered primarily by a shortage of crew under revised duty norms.

Flight disruptions worsen across major airports

IndiGo’s operations remained heavily impacted in Delhi, Mumbai, Bengaluru, Hyderabad, and Ahmedabad, with airports witnessing long queues and frustrated travellers. More than 30 departures from Delhi were scrapped early in the day, while Hyderabad recorded about 33 cancellations. Bengaluru airport confirmed that 73 IndiGo flights were cancelled on Thursday, and Mumbai also saw significant disruptions.

Sources told media that the total cancellations could exceed 170 flights through the day.

Passengers took to social media to highlight severe delays, with some alleging they were kept waiting for more than 12 hours without accommodation or timely updates.

IndiGo cites operational challenges, promises stabilisation

Acknowledging the strain on its vast network of over 2,200 daily flights, IndiGo apologised to customers and attributed the disruptions to multiple factors, including technological issues, winter schedule adjustments, harsh weather, airspace congestion and the new crew rostering rules known as Flight Duty Time Limitations (FDTL).

The airline said it has initiated “calibrated adjustments” to stabilise operations over the next 48 hours.

Crew shortage under revised FDTL rules behind the crisis

A key driver of the ongoing chaos is the shortage of flight crew, especially pilots, following the implementation of the second phase of updated FDTL norms on November 1.

The revised rules mandate longer rest periods, extend night hours, and reduce allowable night landings. Airlines had initially opposed the changes but were required to comply following a court directive.

According to the aviation regulator, IndiGo cancelled 1,232 flights in November alone — 755 of them due to crew and FDTL constraints.

DGCA seeks answers as OTP plunges

The Directorate General of Civil Aviation (DGCA) has summoned IndiGo officials for a review meeting. The regulator said it is assessing the reasons for continuing disruptions and the airline’s recovery plan.

IndiGo’s on-time performance dipped to 67.7% in November, down from 84.1% in October, driven by constraints from crew availability, ATC system failures, airport restrictions and weather factors.

Security forces have intensified their combing operations in the dense West Bastar forests after a fierce encounter left 12 Maoists dead and claimed the lives of three DRG personnel.

A coordinated offensive involving teams of DRG Bijapur-Dantewada, STF, CRPF and CoBRA unfolded deep inside Maoist-dominated terrain early Wednesday. According to Bijapur SP Dr Jitendra Yadav, the forces came under sustained Naxal gunfire around 9 am, triggering a prolonged encounter.

By afternoon, the bodies of 12 Maoist cadres had been recovered, while weapons seized from the area included SLR rifles, INSAS rifles, .303 rifles and other ammunition. Bastar Range IG Sundarraj P confirmed that identification of the deceased Maoists is still underway.

Three DRG personnel killed, two injured

The operation came at a grave cost, with three DRG personnel — Head Constable Monu Waddi, Constable Dukaru Gonde and Jawan Ramesh Sodi — losing their lives. Two others sustained injuries but are reported to be out of danger after receiving medical care.

Chief Minister Vishnu Deo Sai paid tribute to the fallen personnel and lauded the forces, stating that the action reflects a clear weakening of Maoist networks in the region. He said arrangements for treatment of the injured have been ensured and reiterated the government’s commitment to ending Maoist violence.

Forces strengthen search and area sealed

SP Yadav said additional reinforcements have arrived and the encounter zone has been fully cordoned off for intensified operations. Continuous combing is underway to locate remaining Maoist cadres.

Chhattisgarh Home Minister Vijay Sharma noted that forces have been consistently making gains in anti-Naxal missions, calling the latest action a significant strike against Maoist groups.

India’s largest airline, IndiGo, is grappling with widespread disruption across major airports as flight delays and cancellations continue for the second consecutive day. With operations strained and punctuality plunging sharply, thousands of passengers have been left inconvenienced across Delhi, Mumbai, Bengaluru and Hyderabad.

IndiGo’s on-time performance dips sharply

Government data showed the airline’s on-time performance had dropped to 35%, a rare slump for the carrier known for punctuality. IndiGo, which operates more than 2,200 flights daily, saw over 1,400 flights delayed on Tuesday, followed by around 200 cancellations by Wednesday afternoon.

Mumbai Airport issued an advisory alerting passengers to check their flight status, citing airline-related operational issues impacting departures and arrivals.

New duty norms trigger severe crew shortage

A major factor behind the disruptions is the implementation of revised Flight Duty Time Limitation (FDTL) rules last month. The updated norms mandate longer rest hours and more humane rosters for pilots and cabin crew. Sources indicated many flights were grounded over the past 48 hours as crew availability dipped sharply.

IndiGo acknowledged a “multitude of unforeseen operational challenges” including technology glitches, winter schedule adjustments, weather-related issues and the new rostering norms. The airline said it has begun calibrated schedule adjustments for the next 48 hours to restore normalcy.

FDTL rules cap crew flying to eight hours a day and mandate a minimum rest period of 10 hours within a 24-hour window, with rest time amounting to twice the flight duration.

Airports across India see cancellations

The ripple effect of IndiGo’s disruptions has been felt nationwide:

• Hyderabad’s RGIA reported 33 cancellations, leading to long queues and disrupted travel plans.
  
• Bengaluru Airport saw 42 cancellations, including 22 arrivals and 20 departures, impacting routes to Delhi, Mumbai, Chennai, Goa and Kolkata.
  
• Delhi Airport also saw congestion as a slowdown in the Amadeus system, used for check-ins and reservations, added to delays.
  

Passengers vent frustration

Several passengers took to social media to share their ordeal.
One traveller stranded in Hyderabad since early morning said they missed an important meeting due to continuous delays. Another flyer complained their Udaipur-bound flight was repeatedly delayed, calling the experience “a joke”.

IndiGo issues apology, offers rebooking

IndiGo said it is offering alternate travel options or refunds to affected travellers and urged passengers to check their flight status before leaving for the airport. The airline reiterated its commitment to stabilising operations “as quickly as possible”.
