India’s aviation sector has witnessed a significant shift as Bengaluru’s Kempegowda International Airport has officially overtaken Mumbai’s Chhatrapati Shivaji Maharaj International Airport in terms of monthly domestic passenger traffic for the first time in history. This landmark moment not only reflects changing travel patterns and economic dynamics in the South Asian region but also signals the growing prominence of Bengaluru as a major aviation hub. While Delhi Airport maintains its position as the busiest in the country, the ascent of Bengaluru is fueled by the burgeoning technology sector and corporate demand, transforming the landscape of air travel in India.
According to data released by the Airports Authority of India for April 2026, Bengaluru’s airport handled approximately 3,178,826 domestic passengers, while Mumbai’s airport recorded 2,893,286 passengers during the same period. This shift propels Bengaluru to the second position in the country for domestic traffic volume, while Delhi remains the frontrunner with nearly 4.93 million domestic passengers processed in that month.

When analyzing year-on-year changes, Kempegowda International Airport experienced a slight decrease of 0.2% in domestic traffic compared to April 2025. In contrast, Mumbai Airport saw a sharper decline of 12.1% during the same timeframe, paving the way for Bengaluru’s rise in passenger volume.
The growth of Kempegowda International Airport over the last decade is closely linked to Bengaluru’s reputation as India’s leading technology and startup capital. This thriving ecosystem continuously generates demand for both corporate and leisure travel. In the fiscal year 2025-26, the airport achieved a record total of 44.47 million passengers, reflecting a 6.2% increase year-on-year. This breakdown includes a 3.3% growth in domestic traffic, totaling 37.24 million passengers, and an impressive 23.9% surge in international traffic, reaching 7.23 million travelers.
Major domestic airlines such as IndiGo, Air India Express, Akasa Air, and Air India have established robust operations at the airport, expanding connectivity to both tier-1 and various tier-2 and tier-3 cities across India.
The operational capacity of Bengaluru’s aviation hub has significantly increased with the launch and ongoing expansion of Terminal 2. These upgrades have enhanced passenger handling efficiency, enabling airlines to expand their daily flight schedules seamlessly. Currently, the airport boasts direct flights to over 78 domestic destinations and 34 international locations, with further plans to accommodate increased demand, including the construction of a second phase for Terminal 2 and preliminary designs for a future Terminal 3.
Conversely, the drop in domestic traffic at Chhatrapati Shivaji Maharaj International Airport is primarily due to its geographical and operational constraints. Unlike Bengaluru, which has ample land for expansion, Mumbai’s airport is restricted by its dense urban surroundings. Adding to the competition, the newly inaugurated Navi Mumbai International Airport has begun to draw domestic traffic away from the busy Mumbai hub, with major carriers like IndiGo shifting many of their operations there.
Since its opening in late 2025, Navi Mumbai International Airport has quickly become a go-to option for airlines aiming to relieve congestion at the primary airport. Initially launched by IndiGo, which offered connections to 15 cities, the airport’s operations have expanded significantly. By Summer 2026, it was managing over 73 daily departures, with an average passenger volume reaching 50,000 per day, effectively redistributing traffic that once relied on Chhatrapati Shivaji Maharaj International Airport.
Despite losing ground in domestic traffic, Mumbai Airport maintains its lead in overall passenger volume when accounting for international travelers. For April 2026, Mumbai Airport recorded a total of 4.04 million passengers compared to Bengaluru’s 3.68 million. While Mumbai still holds a significant advantage with its global connectivity to Europe, North America, and the Middle East, Bengaluru’s aggressive expansion efforts are narrowing the gap.
The evolving air travel landscape suggests a diversification of travel demand away from traditional, congested metropolitan hubs. As new aviation infrastructure projects, such as Navi Mumbai and the recently operational Jewar Airport, come online, the hierarchy of Indian aviation is poised for further changes. This emerging network aims to alleviate capacity constraints, ensuring a balanced and resilient transit system across India.
