The Indian aviation market continues to be a tale of two giants, with IndiGo maintaining its undisputed leadership while the consolidated Air India Group steadily gains ground. According to the latest data from the Directorate General of Civil Aviation (DGCA) for August 2025, the market is increasingly consolidating into a duopoly, even as newer players like Akasa Air carve out a niche based on operational efficiency.
For travellers and investors trying to understand the competitive landscape, the data reveals a clear hierarchy: IndiGo at the top, a strengthening Air India as the sole full-service challenger, and a handful of smaller carriers fighting for the remaining space.

The DGCA data for August 2025 shows a clear, albeit slightly shifting, competitive dynamic.
-
IndiGo: Maintained its position as the market leader, flying 8.31 million passengers and capturing a 64.2% market share. However, this was a 1 percentage point decline from its peak of 65.2% in July, suggesting the first signs of competitive pressure.
-
Air India Group: Emerged as the primary gainer, strengthening its position as the clear number two. Its market share grew by 1.1 percentage points to 27.3% in August, its highest of the year. The group carried 3.54 million passengers, indicating that its consolidation and network expansion strategies are paying off.
-
Akasa Air: Held its ground as the third-largest carrier with a stable market share of 5.4%. It has firmly established itself ahead of its struggling rival, SpiceJet.
-
SpiceJet: Continued to face significant challenges, with its market share stagnating at a mere 2.0%. The airline's operational capacity remains severely constrained.

In an increasingly consolidated market, operational metrics are crucial differentiators.
-
On-Time Performance (OTP): Reliability is a key battleground where IndiGo excels with a 90.6% OTP across major metro airports. Akasa Air also posted a strong 87.0%, while Air India Group stood at 84.5%. SpiceJet lagged significantly at 68.2%, reflecting its operational distress.
-
Passenger Load Factor (PLF): This metric measures seat occupancy and revenue efficiency. Akasa Air led the industry with an impressive 91.0% PLF, indicating strong demand and efficient capacity management. While SpiceJet also reported a high PLF of 87.0%, this is likely due to operating a minimal schedule at near-full capacity rather than broad market strength.

The Indian aviation landscape has undergone dramatic consolidation. The merger of Air India and Vistara has created a single, unified full-service carrier, making Air India the sole player in this segment. Simultaneously, the merger of Air India Express and AIX Connect has streamlined the Tata Group's low-cost offerings. This has effectively created a duopoly structure where IndiGo and the Air India Group control over 91% of the domestic market.
The financial performance of the airlines shows a stark contrast. In recent quarters, IndiGo reported a net profit of Rs. 2,176 crore. In contrast, the Air India Group recorded a consolidated loss of Rs. 10,859 crore in FY25, highlighting the financial challenges it faces despite its growing market share.

ICRA maintains a 'stable' outlook for the Indian aviation industry, though growth projections for FY26 have been revised downward to 4-6% from earlier estimates of 7-10% due to geopolitical tensions and operational challenges. The industry continues to face headwinds from rising fuel costs and supply chain issues.
However, the long-term potential remains immense. India is the world's third-largest civil aviation market, and passenger traffic continues to grow. Indian carriers are also aggressively expanding their international operations, collectively aiming to cross the 50% international market share mark in 2025.
