Bengaluru 2nd International Airport

Bengaluru's second international airport is no longer just a distant policy promise. The Karnataka government has officially shortlisted three potential locations, the Airports Authority of India (AAI) has completed its on-ground inspection, and tenders for a comprehensive feasibility study have already been floated. The race to build South India's second mega airport is firmly underway.

But with AAI flagging terrain, airspace, and environmental hurdles across all three proposed sites and competing political interests pushing for alternate locations when, where, and how this airport gets built remains a high-stakes open question.

Here is a complete, research-backed breakdown of everything we know so far.

Why Does Bengaluru Need a Second International Airport?

Bengaluru's existing Kempegowda International Airport (KIA) at Devanahalli, which opened in 2008, was designed to handle approximately 20 million passengers per year. It has since far surpassed that number. KIA handled 40.73 million passengers in 2024, recording a 9% growth in air traffic year-on-year. In the first nine months of 2025 alone, it processed 32.4 million passengers.

Industry projections indicate KIA will reach its absolute maximum capacity by the early 2030s. With Bengaluru's tech economy continuing to attract multinational corporations, a growing middle class driving domestic air travel, and the city's population forecast to cross 20 million by 2031, a second airport is not a luxury, it is an infrastructure necessity.

There is also a competitive geopolitical dimension: Tamil Nadu is actively pursuing an international airport near Hosur, approximately 40–50 km from Bengaluru by road. Karnataka's urgency to fast-track its second airport proposal is partly driven by this cross-border aviation rivalry.

Additionally, the exclusivity clause in the current agreement between the Ministry of Civil Aviation and Bengaluru International Airport Limited (BIAL) which prohibits any airport from being built within a 150 km radius of KIA expires in 2033. The Karnataka government is working to finalise a site well before that deadline.

From 7 Locations to 3: How the Shortlisting Happened

The process of finding land for Bengaluru's second airport began formally in June 2024, when the state government initiated a location scouting exercise. Seven locations were initially identified including Tumakuru Road, Mysuru Road, Kunigal Road, Kanakapura Road, Doddaballapur, and Dobbaspet.

After detailed evaluation, the Karnataka government narrowed the list to three sites and formally submitted the proposal to the Union Ministry of Civil Aviation in March 2025. The three shortlisted locations are:

• Site 1 — Kaggalipura (Somanahalli), Kanakapura Road — ~4,800 acres, Bengaluru Urban district

• Site 2 — Harohalli (Chudahalli), Kanakapura Road — ~5,000 acres, Ramanagara district

• Site 3 — Chikkasolur, Nelamangala–Kunigal Road — ~5,200 acres, northwest Bengaluru

The state government informed the Centre that it is ready to provide 4,500 acres of land at any of the three locations for the airport project.

The 3 Shortlisted Locations: A Detailed Comparison

What Are the 3 Locations Shortlisted for Bengaluru's Second Airport?

The Karnataka government has shortlisted three sites: two adjacent land parcels near Kaggalipura and Harohalli along Kanakapura Road in South Bengaluru, and one plot near Chikkasolur on the Nelamangala–Kunigal Road in northwest Bengaluru.

Location 1: Kaggalipura (Somanahalli) — Kanakapura Road

Location: Bengaluru Urban district, approximately 25–30 km from the city centre along Kanakapura Road.

Land Identified: ~4,800 acres

Connectivity: Well-linked to Kanakapura Road, NICE Ring Road, and proposed Green Metro Line extensions.

Advantages:

• Closest to the city centre among the three sites

• Strong road connectivity via NICE Road and Kanakapura Road

• Proximity to Electronic City, Bannerghatta Road, and major residential corridors in South Bengaluru

• Deputy Chief Minister D K Shivakumar has publicly backed this corridor, citing its industrial connectivity

Challenges:

• Higher land acquisition cost due to existing urban development in the area

• Hills on the eastern and western sides raise aeronautical safety concerns

• Proximity to Bannerghatta National Park may require detailed environmental impact assessment (EIA)

Location 2: Harohalli (Chudahalli) — Kanakapura Road

Location: Ramanagara district, approximately 45–50 km from Bengaluru city centre.

Land Identified: ~5,000 acres

Connectivity: Approximately 10 km from the last station on the Green Metro Line; accessible via Kanakapura Road and NH275.

Advantages:

• Larger land parcel with room for long-term airport campus expansion

• Lower land acquisition cost compared to urban sites

• Potential to catalyse a new smart city or satellite town development in Ramanagara district

• Good connectivity to both Mysuru Road and the Bengaluru–Mysuru Expressway

Challenges:

• Environmental clearance concerns due to proximity to forest pockets near Bannerghatta

• Hilly terrain on both sides affecting flight approach and departure paths

• Greater distance from the city may impact passenger convenience without rapid transit links

Location 3: Chikkasolur — Nelamangala–Kunigal Road

Location: Nelamangala taluk, northwest Bengaluru, along National Highway 75 (Bengaluru–Mangalore highway).

Land Identified: ~5,200 acres

Connectivity: On NH 75, which connects Bengaluru to Mangalore; also accessible via the Peripheral Ring Road.

Advantages:

• Largest land area of the three shortlisted sites

• Strategic position on a major national highway with strong cargo logistics potential

• Proximity to existing industrial zones and future development corridors

• Supported by MLAs from North and West Karnataka as it falls on the route toward their constituencies

Challenges:

• Rocky and uneven terrain would require significant land levelling, escalating construction costs

• Hills on the north-eastern and western sides create potential obstacles for air navigation

• Issues with waterlogging reported during AAI's on-site inspection

• Further from South Bengaluru's tech and business hubs, which generate a large share of KIA's current traffic

Side-by-Side Comparison: 3 Shortlisted Sites

What Did the AAI Report Say?

A six-member team from the Airports Authority of India conducted an on-ground inspection of all three sites in April 2025. The pre-feasibility report was submitted to the Ministry of Civil Aviation on June 23, 2025, and subsequently shared with the Karnataka government.

Critically, the AAI report did not recommend any single site. Instead, it documented the challenges at each location:

Terrain issues: All three sites feature hard and soft rocky terrain that would require significant levelling work during construction — particularly the Nelamangala site, where the uneven rocky landscape would substantially inflate project costs.

Airspace constraints: Aircraft movement will be constrained due to restricted airspace at all three sites. The airspace above Bengaluru is currently managed by KIA (BIAL), Hindustan Aeronautics Limited (HAL), and the Air Force Station at Yelahanka. All three proposed sites fall under HAL's airspace jurisdiction, meaning a flexible airspace-sharing agreement between civil and defence aviation authorities will be mandatory before the airport can operate.

Bannerghatta Hill proximity: The AAI report flagged that all three locations are close to the Bannerghatta Hill range, which poses a potential obstacle to safe air navigation. Any hill within or near the site boundary that presents a navigational hazard will require levelling — adding both cost and regulatory complexity.

Environmental sensitivity: The Kaggalipura and Harohalli sites are near forest zones. Detailed aeronautical and ecological studies will be required to obtain clearances.

Waterlogging: Both Kanakapura and Nelamangala sites showed signs of waterlogging during the inspection — a factor that affects foundation engineering and long-term operational safety.

Industries Minister M B Patil clarified that the AAI report is "for reference purposes only" and the state government will commission its own comprehensive techno-economic and financial feasibility study through private consultants. The final location decision will require Cabinet approval.

What Happens Next? The Road to a Final Decision

Following receipt of the AAI report, the Karnataka State Industrial and Infrastructure Development Corporation (KSIIDC) floated tenders in late 2025 for an expert consultancy firm to prepare a location suitability and comprehensive technical and financial feasibility report. The deadline for applications was January 12, 2026.

The government has stated it intends to model this engagement on consultants who handled feasibility studies for recently commissioned international airports at Greater Noida (Jewar) and Navi Mumbai.

Once the private feasibility study is complete, the process will move to:

1. Detailed Project Report (DPR) preparation

2. Cabinet approval for the final site

3. Land acquisition proceedings

4. Environmental Impact Assessment (EIA) and regulatory clearances

5. Airspace earmarking coordination with AAI, HAL, and Indian Air Force

6. Invitation for private developers / Airport Operator

BIAL (the company that manages KIA) has already expressed keen interest in operating the second airport. BIAL Managing Director Hari Marar publicly urged the government to fast-track the process as far back as 2023.

Karnataka's stated target is to have the second airport operational by 2031 — a timeline that most aviation analysts regard as highly ambitious given the regulatory and logistical hurdles still ahead.

The Political Dimension: Competing Interests

The final site selection is not purely a technical decision. Significant political forces are at play.

Deputy Chief Minister D K Shivakumar has publicly advocated for the Kanakapura Road corridor (Sites 1 and 2), citing strong industrial connectivity to Electronic City and South Bengaluru's business zones.

A group of 42 MLAs from North and West Karnataka signed a demand letter pressing for the Sira area well outside the current shortlist to be considered, arguing it would bring economic uplift to underserved districts.

Industries Minister M B Patil has repeatedly stated that the final decision will be merit-based and grounded in the feasibility study results, not political lobbying. The Cabinet will have the final say.

Impact on Bengaluru Real Estate

The announcement of Bengaluru's second airport has already begun triggering real estate interest along all three corridors, particularly on Kanakapura Road.

South Bengaluru has historically been underserved compared to the north (which benefited enormously from KIA's development). A Kanakapura Road airport would likely replicate the same wave of residential, commercial, and plotted development that Devanahalli, Hebbal, and Yelahanka saw after KIA's launch in 2008.

The Nelamangala–Kunigal corridor, if selected, would open up one of Bengaluru's last affordable land banks for large-scale industrial and logistics development, given its proximity to NH 75 and the planned Peripheral Ring Road.

Early-mover investors are already exploring land in Harohalli and surrounding Ramanagara district areas, anticipating that airport-linked infrastructure would dramatically increase land values over the next decade.

How much land has been identified for the second Bengaluru airport?

The state has identified between 4,800 and 5,200 acres across the three shortlisted locations. Karnataka has communicated to the Central government that it is prepared to provide 4,500 acres of land at the chosen site.
