  • Karnataka likely to choose south Bengaluru for its second international airport
  • Hosur’s upcoming airport increases urgency for Karnataka’s project
  • Final decision awaits techno-feasibility study and cabinet approval

With passenger traffic at Kempegowda International Airport crossing design limits, Karnataka is exploring a second airport, likely in south Bengaluru, to meet future demand.

With Bengaluru’s Kempegowda International Airport (KIA) already handling more passengers than its design capacity, the Karnataka government is pushing ahead with plans to build a second international airport in and around the city.

According to officials from the Infrastructure Development Department (IDD), south Bengaluru has emerged as the most suitable region for the new facility, particularly along the Kanakapura Road and Bannerghatta Road corridors, thanks to existing infrastructure and better road connectivity.

The move has gained urgency after Tamil Nadu announced its new airport project in Hosur, which is expected to attract flyers from southern Bengaluru. A senior IDD official said that nearly 40 million passengers out of the projected 85 million travellers at KIA will be from south Bengaluru in the coming years. “If a second airport is not developed in the south, those passengers are likely to shift towards Hosur,” the official noted.

However, despite this preference, Infrastructure Minister M.B. Patil has clarified that the government will not finalise any site before completing a detailed techno-feasibility study. “All three proposed sites will undergo evaluation by a reputed consultant experienced in greenfield airport projects,” he said.

The study will assess factors such as airspace management, environmental impact, land availability, and financial feasibility before a final decision is presented to the cabinet. Officials estimate the cost of the new airport project at around ₹10,000 crore.

The state government sees this project as vital to managing the doubling of passenger traffic expected over the next decade. Yet, identifying suitable land within a 100-120 km radius of the city remains a major challenge, given the urban sprawl and environmental restrictions.
