Fleet Expansion and Airline Growth
India’s airlines are preparing for this infrastructure boom with massive aircraft orders:
- IndiGo has placed a record order for 500 Airbus planes, with nearly 1,000 aircraft on order as of January 2025.
- Air India follows with 470 aircraft on order.
In total, Indian carriers have ordered 1,359 aircraft, the largest order book in the country’s history. This expansion is supported by a 9% increase in scheduled airline capacity, reaching 240 million seats across domestic and international routes. Over the past 20 years, the sector has grown at an average annual rate of 8.7%.

Policy Bottlenecks: The Main Constraints
Despite these impressive developments, India’s aviation sector faces significant policy bottlenecks that threaten to limit the impact of new megahubs.
1. Outdated Air Service Agreements (ASAs)
India has 116 air service agreements with other countries. These agreements set the rules for how many flights and seats can operate between India and each partner country. Many of these agreements are outdated and do not match current demand.
- The India-Dubai agreement still caps each side at 65,000 weekly seats, a limit set in 2014 and now almost fully used.
- Similar restrictions exist with other Emirates, including Abu Dhabi, Sharjah, and Ras Al Khaimah.
- These limits hurt the 4 million-strong Indian diaspora in the UAE and restrict direct flights.
Consequences:
– Higher fares during holidays and peak travel times.
– Travelers are forced to take longer routes through other hubs like Doha or Riyadh.
– New terminals at aviation megahubs risk being used mainly for domestic flights, with limited international operations.
2. Airspace Utilization Issues
Nearly 40% of Indian airspace is controlled by the military. This forces commercial flights to take longer, less direct routes, increasing flight times, fuel use, and costs.
Visual Description:
Imagine a map of India with commercial flight paths. Many routes curve around restricted areas, showing how military-controlled airspace creates longer journeys and higher costs for airlines and passengers.
Recent Policy Developments
The Indian government has taken some steps to modernize aviation policy, but key reforms—especially to bilateral agreements—remain unaddressed.
Legislative Updates
- The Bharatiya Vayuyan Adhiniyam 2024 replaced the old Aircraft Act of 1934, bringing Indian aviation law closer to global standards.
- The Protection and Enforcement of Interest in Aircraft Objects Bill, 2025 was introduced to address international aviation asset recovery disputes.
Regional Connectivity: The UDAN Scheme
The UDAN (Ude Desh ka Aam Naagrik) scheme aims to improve regional air connectivity:
- 619 routes operational as of January 2025.
- 88 previously unserved or underserved airports now in use, including 13 heliports and 2 water aerodromes.
- Over 14.8 million passengers served through more than 290,000 flights.
The Union Budget 2025–26 proposes a modified UDAN scheme, adding 120 new destinations and aiming to carry 40 million additional passengers over the next decade.
Budget Allocations
The Ministry of Civil Aviation received ₹24 billion in the 2025–26 budget. However, there was no change in the tax treatment of Aviation Turbine Fuel (ATF), disappointing industry hopes for inclusion under the Goods and Services Tax (GST) regime.

Critical Challenges Facing the Sector
1. Fuel Costs and Taxation
High fuel costs remain a major problem. Airlines pay different tax rates for ATF in each state, making fuel more expensive and unpredictable. The industry has called for ATF to be included under GST to create uniform pricing and reduce costs.
2. Pilot Shortage
India faces a shortage of trained pilots, with a gap of about 15%. With so many new planes on order, this shortage could get worse unless training capacity is increased. The Airports Authority of India has allocated 15 slots for Flying Training Organizations at 10 airports, but only 5 are currently operational.
3. Sustainability Requirements
Starting in 2027, India must comply with the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA). Airlines will need to cut carbon emissions for international flights, either by using Sustainable Aviation Fuel (SAF) or by buying carbon credits. However, there is no clear regulatory plan for how India will meet these requirements.

Comparisons, Trends, and Patterns
- Infrastructure vs. Policy: India’s airport capacity is growing faster than its international flight rights. While Delhi airport and other megahubs can handle more passengers than ever, international seat caps and airspace restrictions mean these facilities may not reach their full potential.
- Domestic vs. International Growth: Domestic air travel is booming, supported by the UDAN scheme and new regional routes. International growth is held back by policy bottlenecks, especially with key markets like the UAE.
- Global Context: India’s rise to the world’s third-largest aviation market is impressive, but without policy reforms, it risks falling behind other aviation megahubs that have more flexible international agreements and better airspace management.
Evidence-Based Conclusions
India’s aviation sector stands at a crossroads. The country has built world-class aviation megahubs and airlines are ready to expand, but policy bottlenecks—especially outdated bilateral agreements and airspace restrictions—are holding back international growth. Without urgent reforms, there is a real risk that new airports like Delhi, Navi Mumbai, and Jewar will operate below their international capacity, limiting benefits for travelers, airlines, and the broader economy.
Limitations
- The analysis is based on the latest available data as of June 2025. Policy changes or new agreements after this date are not included.
- Some data on pilot training capacity and sustainability regulations remain incomplete, as government plans are still under development.
Expert Recommendations
Aviation experts and industry analysts have suggested several steps to address these challenges:
- Renegotiate Bilateral Agreements: Update air service agreements with key partners, especially the UAE, to allow more flights and seats, reducing fare spikes and improving connectivity.
- Release Military Airspace: Gradually open more airspace for civilian flights to shorten routes, cut fuel use, and lower costs.
- Expand Pilot Training: Increase the number of Flying Training Organizations and invest in pilot education to meet future demand.
- Develop Domestic MRO Ecosystem: Lower GST on Maintenance, Repair, and Overhaul (MRO) services and offer tax breaks to attract private investment and make India a competitive MRO hub.
