The distance from Electronic City Bengaluru to Kempegowda Airport depends a lot on who you ask. Kayak lists The Oterra hotel at 39.2 km from the airport. An office-space listing for Tech 37 says 50.9 km. The BMTC airport bus route from Electronic City covers about 60 km, and Lemon Tree Hotel, Electronics City, quotes about 63 km. The difference comes from the route: a straight drive through the city is shorter than the airport bus’s loop around the Outer Ring Road.
What they all agree on is that this is a long trip. Kempegowda International Airport is on the far north side of Bengaluru, and Electronic City is on the far south. Here’s how to plan it.

Actual travel time depends heavily on traffic, time of day and route.
Option 1: The KIAS-8 Airport Bus
BMTC’s Vayu Vajra airport service runs route KIAS-8 between Kempegowda International Airport and Electronic City.
Key details (from a published route guide):
- Distance: about 60 km
- Journey time: about 2–3 hours, depending on traffic
- Operating hours: listed as 24×7, seven days a week
- Frequency: every 10 to 40 minutes
The route: the bus takes the eastern side of the city rather than going through the centre. Its stops include:
- I.A. Terminal 2 and the airport road toll
- Yelahanka Air Force Station area and Kogilu Cross
- Hebbal (Esteem Mall and Hebbal Bridge)
- Nagavara and Kalyan Nagar
- R. Puram Metro Station
- Marathahalli Bridge
- Central Silk Board, then on to Electronic City
Why take the bus:
- It runs around the clock, useful for early and late flights
- It’s usually far cheaper than a cab
- BMTC has offered a group discount on KIAS-8 in the past for three or more people travelling together. Check whether it still applies.
Note on the buses: BMTC has been introducing air-conditioned electric buses on Vayu Vajra routes, starting with 8 to 10 buses and planning to scale up to 83 as charging infrastructure is built. You may get either a diesel Volvo or a newer e-bus.
Option 2: Driving or a Cab
For most travellers, a cab is the fastest option, especially outside peak hours. Hotels in Electronic City estimate about 1.5 hours.
Common road approaches:
- Through the city: Hosur Road and the Electronic City Elevated Expressway toward Silk Board, then north through central Bengaluru toward Hebbal and the airport road
- Around the eastern ORR: Silk Board to Marathahalli, K.R. Puram and Hebbal, similar to the KIAS-8 bus route
Which is faster? It depends on the time of day. Check live traffic before you leave and let your navigation app choose.
Tolls to expect:
- The Electronic City Elevated Expressway is a toll road
- The airport road has a toll plaza near the airport
Option 3: Metro Plus Cab or Bus
There’s no direct metro to the airport from Electronic City yet. But the Yellow Line, open since 11 August 2025, can get you past Hosur Road traffic for the first part of the journey.
One practical combination:
- Take the Yellow Line from Electronic City to Central Silk Board
- Board KIAS-8 or another airport service from Silk Board, or take a cab from there
Coming later: the Blue Line is planned to link the Outer Ring Road with the airport, with a future interchange at Central Silk Board. Once it opens, the metro should become a real option for the full trip. I couldn’t confirm an opening date.
When to Leave for Your Flight
| Your situation | Suggested buffer |
| Domestic flight, off-peak cab | Leave about 3 hours before departure |
| Domestic flight, peak hours | Leave 3.5 hours or more before departure |
| International flight | Add at least an hour more |
| Taking KIAS-8 | Allow for the 2–3 hour journey plus waiting time |
These are planning estimates. Adjust for weather, events and your airline’s check-in rules.
Tips for the Airport Run
- Avoid weekday peak hours on Hosur Road and the Outer Ring Road where possible.
- Book early-morning cabs the night before.
- Keep toll money or FASTag balance ready if you’re driving.
- Check the terminal. The KIAS-8 route lists Terminal 2 among its stops. Confirm your airline’s terminal.
- Watch for rain. Monsoon downpours can slow traffic significantly.
