Shares of InterGlobe Aviation Ltd, the operator of IndiGo Airlines, fell by around 8 per cent in today’s trading session. The decline followed fresh operational disruptions triggered by the implementation of new Flight Duty Time Limitation (FDTL) rules, which led to the cancellation of over 3000 flights in the last five days, as per the news reports. Concerns around short-term capacity constraints, flight delays, crew availability and near-term execution challenges unsettled investor sentiment, resulting in sharp selling pressure.
While these developments explain the immediate market reaction, they do not alter a larger and more important structural reality: IndiGo remains the most dominant airline India has ever seen, operating at the centre of one of the fastest-growing aviation markets globally. To understand why, one must first step back and examine the broader Indian aviation landscape
India’s Civil Aviation Industry: A Structural Growth Engine
India’s civil aviation sector has emerged as a core pillar of economic growth, enabling mobility, tourism, business travel and regional connectivity. The country is currently the third-largest domestic aviation market in the world, supported by rising disposable incomes, rapid urbanisation and a strong shift in consumer preference towards air travel.
Passenger traffic (domestic and international combined) stood at 96.54 million during FY26 (April–July 2025), while air freight traffic touched 1.2 million metric tonnes in the same period. According to ICRA, domestic passenger traffic is projected to grow 7–10 per cent YoY in FY26, reaching 175–181 million passengers.
Infrastructure expansion has been a major growth catalyst. India’s airport network has expanded from 74 airports in 2014 to around 157–162 operational airports in 2025. Looking ahead, India plans to scale this to nearly 220 airports by 2030, adding 60+ new airports and upgrading existing infrastructure, with 50 major aviation development projects planned over the next five years. This expansion is expected to significantly improve connectivity across tier-2 and tier-3 cities.
Fleet Expansion: Building Capacity for the Next Decade
Reflecting confidence in long-term demand, Indian airlines have placed one of the largest aircraft order backlogs globally.
- IndiGo has placed orders for around 1,370 Airbus aircraft, with roughly 460–470 already delivered, leaving a backlog of approximately 900 aircraft.
- Air India Group has firm orders for 570 aircraft as part of its fleet modernisation under the Tata Group.
- Akasa Air has placed confirmed orders for 226 Boeing 737 MAX aircraft.
- Smaller incremental additions come from SpiceJet and regional operators
Cumulatively, the Indian airline industry holds an order backlog of 1,600–1,700 aircraft, positioning India as one of the fastest-growing aviation markets globally over the next decade.
IndiGo’s Market Dominance: Unmatched Scale
Despite rising competition, IndiGo commands an extraordinary lead in India’s aviation market. Domestic Market Share (Aug–Oct 2025)
IndiGo: 64 per cent
Air India Group: 27 per cent
Akasa Air: 5 per cent
Others: 4 per cent
In effect, nearly two out of every three domestic airline passengers in India fly IndiGo. Such sustained dominance is rare in global aviation, particularly in price-sensitive emerging markets
IndiGo’s Unique Operating Model
IndiGo’s dominance is not cyclical; it is structural, rooted in a business model that has remained consistent and disciplined.
Pure Low Cost Strategy: IndiGo follows a single-minded low cost carrier (LCC) approach, avoiding the complexity of full service offerings. No free meals, no seat classes and limited frills ensure tight cost control and operational simplicity.
Fleet Commonality Advantage: IndiGo largely operates a single aircraft family (Airbus A320neo/A321). This provides: Lower pilot training costs, Simplified maintenance, Faster turnaround times and Reduced spare inventory. These efficiencies directly translate into a lower cost per available seat kilometre, a decisive competitive advantage
High Aircraft Utilisation: IndiGo consistently ranks among airlines with the highest aircraft utilisation rates in the world, ensuring that planes spend more time flying and less time on the ground critical in a fixed cost-heavy business.
Network Density and Slot Control: The airline has secured valuable airport slots across metros and key regional hubs, creating natural entry barriers. New airlines find it extremely difficult to replicate IndiGo’s network depth quickly
Financial and Lease Discipline: Historically, IndiGo maintained prudent balance sheet management, using sale and leaseback strategies, strong cash buffers and disciplined expansion, allowing it to survive downturns that forced competitors out
Competitive Landscape: Why the Gap Persists
Air India’s revival under the Tata Group is narrowing service quality gaps while Akasa Air brings agility. However, matching IndiGo’s scale unit economics and execution capability remains a formidable challenge. Air India is still in a complex integration phase involving multiple fleets, brands and legacy systems. Akasa, while nimble, lacks scale. IndiGo’s early mover advantage, network density and cost leadership keep it structurally ahead
Short-Term Disruptions vs Long-Term Structure
Recent flight cancellations linked to new FDTL regulations have highlighted the operational complexity of running a massive airline at scale. However, such disruptions reflect execution challenges in a growing industry, not a breakdown of IndiGo’s competitive position
India’s aviation demand continues to rise, infrastructure is expanding aggressively and airlines with scale and discipline are best positioned to benefit. Historically, IndiGo has outlasted peers during oil shocks, pandemics, regulatory shifts and pricing wars.
The Bigger Picture
The Indian aviation industry stands at the cusp of multi-year structural growth, supported by favourable demographics, infrastructure investments and rising incomes. Within this ecosystem, IndiGo has emerged not merely as a large airline but as the operating benchmark of the sector. Short-term volatility, whether due to operational rules, costs, or sentiment, does not change the fundamental equation. Market leadership in aviation is determined by scale, cost control, network density and execution discipline
IndiGo’s dominance illustrates what happens when a simple model is executed relentlessly in a structurally expanding market. While operational turbulence may arise from time to time, the airline’s position within India’s aviation ecosystem remains deeply entrenched. In a sector defined by high fixed costs and thin margins, the player with structural advantages tends to dominate for long periods. In India’s aviation story, that player so far has clearly been IndiGo.
