NEW DELHI: If you’ve been stranded at a major airport like Delhi, Mumbai, or Bengaluru this week, you’re not alone. IndiGo, the airline you usually count on for timely travel, has been plunged into a full-blown crisis, forcing the cancellation of hundreds of flights and leaving passengers furious and stuck.
On Thursday alone, the airline was forced to scrap an estimated 250 flights, following around 150 cancellations the day before. The chaos has been so severe that the airline’s On-Time Performance (OTP) plunged as low as 19.7% in one day, a stunning drop for a carrier usually known for its punctuality.
So, what exactly is going on? The problem isn’t just one thing, it’s a perfect storm of operational hiccups colliding with a strict new rulebook.
Crew Shortage Meets New Rules:
The core of the crisis lies in a severe crew shortage, particularly among pilots, stemming directly from the recent implementation of updated crew rostering rules, known as Flight Duty Time Limitations (FDTL).
Here are the key details that led to this massive disruption:
1. The FDTL Rule Change (The Main Driver)
What changed: The Directorate General of Civil Aviation (DGCA) rolled out the second phase of stricter FDTL norms on November 1. These rules are designed to combat pilot and crew fatigue by mandating more rest and humane rosters.
The new rules require an increase in weekly rest periods to 48 hours and significantly limit the number of night landings (down to two, from six earlier).
Because IndiGo runs an extremely tight schedule, especially with many flights operating at night, these stricter rest requirements instantly created a massive deficit in available crew, forcing the airline to cancel flights when reserve pilots couldn’t be rostered within the new legal limits. DGCA data showed that even in November, 755 flights were cancelled specifically due to FDTL constraints.
2. The Compounding Factors
IndiGo’s spokesperson acknowledged that the FDTL issue was compounded by several other factors:
Technology Glitches: Minor software problems, including an emergency Airbus A320 software patch rushed through earlier, disrupted the crucial crew scheduling systems. Problems with baggage systems at Delhi airport also added to the turmoil.
Seasonal & System Congestion: Schedule changes linked to the winter season and increased overall congestion in the aviation system further complicated matters.
Adverse Weather: Unforeseen bad weather conditions also contributed to delays, rapidly consuming the minimal slack the airline had in its crew schedules.
The Airline’s Response and Regulator’s Action:
As passengers raged on social media and confronted airport staff with reports of travellers stranded for over 15 hours both the airline and the regulator were forced to act.
What IndiGo Said:
In a public statement, IndiGo apologized, acknowledging that operations were “significantly disrupted”. It stated: “To contain the disruption and restore stability, we have initiated calibrated adjustments to our schedules.” The airline announced that these measures would remain in place for the next 48 hours to allow them to stabilize operations and recover punctuality. Customers affected are being offered alternate arrangements or refunds.
What the DGCA Did:
The aviation watchdog has launched a probe into the flight disruptions. The DGCA officially summoned IndiGo officials to its headquarters to “present the facts leading to the current situation” and to outline a concrete plan to mitigate the ongoing wave of delays and cancellations.
