Bengaluru’s Rs 1,500 airport cab rides could soon get cheaper as Blue Line takes shape: Check operation timeline, route and other details

For Bengaluru commuters tired of spending around Rs 1,500 on a cab ride to Kempegowda International Airport, a cheaper alternative is taking shape. Namma Metro’s Blue Line will connect the city to KIA, though commuters will have to wait a little longer for the full route to become operational.

The 58-km Blue Line, which will connect Central Silk Board with Kempegowda International Airport, is now expected to become fully operational by March 2028. The corridor will open in phases, with the airport stretch scheduled to be commissioned before the entire line is completed.

Airport Metro link targeted for September 2027

According to the latest schedule, the Hebbal-KIA section is targeted for opening by September 2027. The Central Silk Board-KR Pura stretch is expected to begin commercial operations by mid-2027, while the remaining KR Pura-Hebbal section is likely to be completed between December 2027 and March 2028.

The Blue Line will give passengers a direct Metro option to reach KIA, potentially reducing their dependence on taxis and private vehicles for airport trips.

The airport connection is part of the larger Blue Line being built along Bengaluru’s traffic-heavy Outer Ring Road. The corridor will connect major employment hubs and residential areas before extending northwards towards the airport.

Why is Bengaluru’s airport Metro taking so long?

The Blue Line has faced several construction and integration challenges.

One of the key challenges is the section between Hebbal and Kempapura, where BMRCL is constructing infrastructure capable of accommodating four Metro tracks. The design will allow the Blue Line to integrate with the proposed Orange Line in the future.

Officials said a specialised three-pier portal structure is being built along about 1 km between Hebbal and Kempapura to accommodate the four tracks. It will be the first such configuration on Namma Metro’s mainline network.

Construction along the Outer Ring Road has also been complicated by heavy traffic, utility-related issues, land constraints and station construction challenges.

From airport cabs to driverless Metro

The Blue Line will also introduce driverless Metro technology to Bengaluru. Its trains are equipped with automated control and safety systems and will undergo extensive testing before passenger services begin.

For airport travellers, however, the biggest change could be much simpler: having the option to leave the car or cab behind.

Once the Hebbal-KIA stretch opens, passengers from several parts of Bengaluru will be able to take the Metro to the airport, with connectivity expected to improve further as the remaining sections of the Blue Line become operational.

Bengaluru airport passenger fee cut by 45%

Domestic air passengers flying out of Bengaluru will pay significantly less in airport user charges from September 1, with the Airports Economic Regulatory Authority of India (AERA) fixing the User Development Fee (UDF) at Rs 300 per departing passenger for the five-year period through March 2031.

The revised fee is 45% lower than the existing Rs 550 and also below the Rs 450 proposed by airport operator Bangalore International Airport Ltd (BIAL). The reduction is particularly significant for Bengaluru, where domestic travellers account for about 84% of total passenger traffic.

For departing international passengers, the UDF has been set at Rs 997, compared with the existing Rs 1,500 and BIAL's proposed Rs 1,215, AERA said in a release on Friday. The regulator's decision comes as part of the fourth control period, which runs from April 1, 2026, to March 31, 2031. However, the revised UDF will be levied from September 1, 2026.
