How a Small Leave Policy Brought India’s Largest Airline to Its Knees: Lessons from the IndiGo Crisis
In early December 2025, Indian aviation witnessed something unexpected:
A small regulatory change created a massive operational mess, forcing the government to roll back its own decision within days.
At the center of this storm stood IndiGo, India’s largest airline, operating nearly 2,000 flights a day.
What happened is a classic example of how even minor-looking policy changes—if not fully impact-assessed—can deeply disrupt an entire industry.
The Policy: No Substitution of “Leave” for “Weekly Rest”
Recently DGCA introduced a new rule under revised Flight Duty Time Limitations (FDTL):
> A pilot or crew’s leave could not be counted as their weekly rest.
Weekly rest had to be taken separately, even if the crew had already availed 24–48 hours of leave.
At first, this looks like a technical, harmless adjustment introduced to reduce pilot fatigue.
But for an industry operating on thin resources, tight schedules, crew shortages, and weather disruptions—
This rule hit like a hammer. What Followed: A Nationwide Ripple Effect
1. Massive flight cancellations
> IndiGo alone had to cancel 1,200+ flights within a last few days.
> Crew scheduling became impossible because pilots on leave could not be rostered back unless they got a separate weekly rest block.
2. Airports across India went into chaos
> Delhi, Mumbai, Bengaluru—queues stretched for hours.
>Flyers missed connecting flights, weddings, interviews, medical appointments.
3. Passenger trust took a hit
> Airlines can recover losses later, but passengers cannot recover the time, money, and plans lost.
4. Government forced to step in
> Realising the intensity of disruption, DGCA withdrew the clause and restored flexibility:
>Leave can again be treated as weekly rest for rostering purposes.
This U-turn shows just how badly the industry was hit—and how urgently the government needed to repair the situation.
So the question is why Did Such a Small Rule Create Such a Big Mess?
> Because in aviation, operations work like a chain reaction.
> A pilot not available → affects one flight → which affects the next crew → which affects the aircraft rotation → which delays multiple flights → which clogs airports → which causes nation-wide disruption.
This clearly shows that One tiny bottleneck can collapse the entire system.
This rule:
> reduced crew availability
> created gaps in rosters
> caused aircraft grounding
> multiplied delays → cancellations → chaos
IndiGo, with the largest fleet and highest frequency, took the hardest hit.
Lesson to be learned : Policy Impact Must Be Assessed Before Implementation
This incident teaches a crucial governance lesson that Even the smallest policy changes can create disproportionate consequences when applied to a high-dependency, high-scale system.
So in our opinion before introducing any regulatory change—especially in aviation—policymakers must ensure:
> Impact simulations: Run practical scenarios on actual airline rosters.
> Stakeholder consultations :Pilots, airline operators, airport authorities.
> Transition periods: Avoid sudden enforcement during peak travel seasons.
> Operational readiness checks: Ensure airlines have buffer crew or alternate arrangements.
Had this been done, the industry would not have faced:
> thousands of stranded passengers
> massive commercial losses
> reputational damage
> a forced rollback
Aviation deserves precision, not trial-and-error.
Will Airlines Recover?
> Financially, yes.
> Operationally, likely soon.
> But reputationally—IndiGo and others will need to work harder to regain passenger trust.
“Passengers remember disruptions longer than balance sheets do.”
Conclusion: Small Policies Can Create Big Damage
The IndiGo episode is a stark reminder that:
1. Policy decisions must be backed by robust operational analysis.
2. The aviation ecosystem is extremely sensitive to manpower-related rules.
3. Even a minor-looking rest/leave policy can trigger nationwide turbulence.
4. Government and regulators must work hand-in-hand with industry—not in isolation.
In the future, policy impact assessment must be a mandatory step, not an afterthought.
> Aviation is not an industry where you experiment first and correct later.
> Because here, even one small rule can clip the wings of an entire nation’s travel network.
