NMIA's Domestic Operations Surge
Navi Mumbai International Airport (NMIA) has begun domestic flights with rapid growth, currently handling 20,000 passengers and 150 air traffic movements (ATMs) daily. Projections show this could rise to 50,000 passengers and 380 ATMs daily by the end of 2026, reflecting demand for the new airport. This domestic success is part of Adani Group's plan to invest ₹2 lakh crore in new projects over the next five years. Adani Enterprises Ltd. (ADANIENT) traded around ₹2,250-₹2,314 on April 23, 2026, with a P/E ratio around 21.8, while Adani Ports & SEZ (ADANIPORTS) traded near ₹1,585-₹1,607 with a P/E ratio around 29.3.
IndiGo's Dominant Role
IndiGo is key to NMIA's initial success, handling an estimated 70% to 80% of daily flights. The airline launched commercial operations at NMIA, connecting it to many domestic cities. However, this heavy reliance on one airline increases operational risks, especially as the Indian aviation sector faces significant challenges.
Geopolitical Pressures and Sector Outlook
While NMIA's projected 380 daily ATMs are significant, Mumbai's existing Chhatrapati Shivaji Maharaj International Airport (CSMIA) handled 55.5 million passengers and 331,011 ATMs in 2025. NMIA's Phase 1 capacity of 20 million passengers annually is intended to ease congestion and increase overall regional capacity. However, the growing Gulf conflict has delayed international flights at NMIA. This geopolitical instability is a concern for the Indian aviation industry, leading ICRA to revise its outlook to negative. Rising jet fuel (ATF) prices, a weaker rupee, and flight rerouting due to closed airspace are increasing operating costs, which could lead to ₹17,000-₹18,000 crore in net losses for the sector in FY26. Air cargo rates from India to the US have jumped 200-350% due to limited capacity.
Risks: Delayed International Flights and IndiGo Dependence
The delay in international operations at NMIA because of the Gulf War limits revenue and growth potential. These geopolitical tensions also raise fuel costs and hurt airline profits, with many carriers already struggling financially. Air India has added fuel surcharges, and the industry is expected to report large losses. NMIA's heavy reliance on IndiGo also creates a significant concentration risk. If IndiGo faces problems, it could heavily impact NMIA's performance. This is especially true as other Indian airlines also deal with rising costs and limited capacity on key international routes to the Gulf, a major part of international travel for Indian carriers. Gulf airlines, with their established hub networks, are better positioned to handle these disruptions than Indian airlines.
Outlook Amidst Challenges
Despite current geopolitical issues affecting international flights and the wider aviation sector, NMIA's domestic growth remains positive. Analysts expect a tough near-term for Indian aviation, projecting domestic passenger growth at 0-3% and international growth at 7-9% for FY26, much lower than earlier estimates. NMIA's ability to manage these external pressures and its reliance on IndiGo will be crucial for its long-term success as a major aviation hub for the Mumbai region.
