Not joining any party; I am a doctor, would like to remain so: Dr Kafeel Khan

IndiGo, India’s largest airline, is battling one of its worst operational disruptions in recent years, with hundreds of delays and cancellations throwing domestic travel into chaos.

Government data on Tuesday showed its on-time performance plunging to 35%, an unusual dip for a carrier long associated with punctuality.

By Wednesday afternoon, airports in Delhi, Mumbai, Bengaluru and Hyderabad had collectively reported close to 200 cancellations, stranding travellers across the country.

Crew Shortage After New Duty Norms

A major trigger behind the meltdown is a severe crew shortage, especially among pilots, following the rollout of revised Flight Duty Time Limitation (FDTL) norms last month.

The rules mandate longer rest hours and more humane rosters — a shift IndiGo has struggled to incorporate across its vast network.

Sources said several flights were grounded due to lack of cabin crew, while some delays stretched upwards of eight hours.

With IndiGo controlling over 60% of India’s domestic aviation market, the ripple effect has impacted airports nationwide.

IndiGo Issues Apology, Lists “Compounding Factors”

In a statement, IndiGo acknowledged the large-scale disruption:

“We sincerely apologise to customers. A series of unforeseen operational challenges — technology glitches, winter schedule changes, adverse weather, system congestion and updated FDTL norms — created a compounding impact that could not have been anticipated.”

To stabilise operations, the airline has begun calibrated schedule adjustments for the next 48 hours, aiming to restore punctuality. Affected passengers are being offered refunds or alternate travel arrangements, IndiGo said.

What the FDTL Rules Require

The FDTL norms, designed to reduce pilot fatigue, cap duty and flying hours as follows:
•    Maximum 8 hours of flying per day
•    35 hours per week
•    125 hours per month
•    1,000 hours per year

Crew must also receive rest equalling twice the flight duration, with a minimum 10-hour rest period in any 24-hour window.

The DGCA introduced these limits to enhance flight safety.

Hyderabad: 33 Flights Cancelled, Long Queues Reported

Hyderabad’s Rajiv Gandhi International Airport saw heavy early-morning crowds as 33 IndiGo flights (arrivals and departures) were cancelled.

The airport clarified on X that operations were normal, advising passengers to contact IndiGo directly for latest flight status.

Cancellations included flights to and from Visakhapatnam, Goa, Ahmedabad, Delhi, Bengaluru, Chennai, Madurai, Hubli, Bhopal and Bhubaneswar.

Bengaluru: 42 Flights Disrupted

Bengaluru’s Kempegowda International Airport recorded 42 cancellations — 22 arrivals and 20 departures — affecting routes to Delhi, Mumbai, Chennai, Hyderabad, Goa, Kolkata and Lucknow.

Passengers Vent on Social Media

Irate travellers took to X to share their experiences. One passenger stranded in Hyderabad wrote: “I have been here since 3 a.m. and missed an important meeting.”

Another said: “My flight was pushed from 1:55 PM to 2:55 PM and now 4:35 PM. I was informed only three minutes before entering the airport.”

Delhi Airport Hit by Tech Glitch

At Delhi Airport, the disruption deepened due to a slowdown in the Amadeus system — used for reservations, check-ins and departure control.

The technical issue led to longer queues and sluggish processing, adding to delays already worsened by staff shortages.

Mangaluru, Dec 2: Mangaluru International Airport responded to a medical emergency late on Monday night. Air India Express flight IX 522, travelling from Riyadh to Thiruvananthapuram, was diverted to Mangaluru Airport after a passenger in his late 30s experienced a medical emergency on board.

The Airport’s Operations Control Centre received an alert regarding the passenger’s health condition. The airport activated its emergency response protocol, mobilising the airport medical team and coordinating with stakeholders including CISF, immigration, and customs. 

Upon landing, airport medical personnel attended to the passenger, assessed his condition, and arranged to shift him to a local tertiary-care hospital for further treatment. The passenger’s relatives accompanied the passenger, who incidentally received necessary medical care on board, which helped stabilise the situation.

Following the handling of the emergency, the flight departed for Thiruvananthapuram at 2:05 am on Tuesday.

"We appreciate the cooperation of all parties involved, and this incident reaffirms our ongoing commitment to prioritising passenger safety and readiness to respond to unforeseen emergencies with professionalism and care," the Airport spokesperson said. 

Mangaluru, Dec 15: Air India Express has announced that it will resume direct flight services between Mangaluru and Muscat from March 2026, restoring an important international air link for passengers from the coastal region.

Airport authorities said the service will operate twice a week—on Sundays and Tuesdays—from March 1. The initial flights are scheduled on March 3, 8 and 10, followed by March 15 and 17, with the same operating pattern to continue thereafter. The flight duration is approximately three hours and 25 minutes.

The Mangaluru–Muscat route was earlier operated under the 2025 summer schedule, with services beginning on July 14. At that time, Air India Express had operated four flights a week before suspending the service.

Officials said the summer schedule will come into effect from March 29, after which changes in flight timings and departure schedules from Mangaluru are expected. Passengers have been advised to check the latest schedules while planning their travel.

The resumption of direct flights to Muscat is expected to significantly benefit expatriates, business travellers and others, further strengthening Mangaluru’s air connectivity with the Gulf region.
